Tyler,
First thing, make sure you are using the same controller. If you are, it's most likely my code. I have had some bugs so. I changed hardware version, but the display is wired the same right now.

Not everything is working yet, but this *should* display pixels if you have the same controller.
eagletalontim, I can't work on the sd card right now, but hopefully dr A will figure this out. It would be a real bummer to find out the cage itself is bad. I hope I was doing something wrong. I was looking at the 5v crowd and they seem to have it working. I would THINK just removing the resistors would work, but bypassing may be key too. All I know is I tried both and I still have nothing. I'm making progress with the analog board, but still having issues. Time to RTFM...
Thanks, for the reply i'll try that out. I have tried to get the sd card working to and no luck so far. Weird i was hoping to use it and save some space(and money).
Tyler, which controller does your display use? Which display are you using? The one thing that comes to mind is POR values. Your display MAY NOT have the same Power On Reset values even if it is the same controller.
I am commenting code right now. I used to be in the habit of commenting as I wrote. I have been slacking off a bit.
I still have not been able to get my analog board to work. I will be switching back to my BS2 to test the control circuitry I added. The board was working with the BS2before I added the control circuitry. I'm hoping I'm just doing something wrong.
Found another wiring mistake. I wired DEV_SPI_ADD_LE to DEV_SPI_EN. I am correcting this now.
Other bugs found. Fixing those as well. I will be updating the final rev of ScreenTest shortly.
Thanks for the commented code i'll look at that later today when I have time. I hope Dr. A can firgure out the sd card, i can't. I read on a gadget gangstar forum that when not using PSM Sd Card reader your must put the Cs first instead of Do. As in:
...mount_explicit(CS, DI, CLK, DO) 'Gives me -100
instead of:
...mount_explicit(DO, CLK, DI, CS) 'Gives me -1
But unfortunately it doesn't seem to work, but mabye switching the order will provide a fix for this pesky sd card reader.

I will have to look into this. I have most of my hardware revisions done. I think I will leave multiplexing the parallel bus for later when I need it. I have one more chip to mount and connect on my analog board, which is fully working now. Hopefully all will go well with this.
Just got my screens in today I ordered 2 and got 4. Guess it is an error in my favor. I will continue to follow this thread for updates on the SD card reading. Just have to get mine to turn on, then display a pixel... the fun begins!
@ eagle, Awesome! I want to order 4 more of these things. I'm about ready to start working on the sd card, although I don't think I need it yet. I've been writing and drawing a GUI. I still haven't bound anything yet, but it's getting close. I'm getting excited at the potential. I'm still using spin drivers to write the display which is slow. I will be converting to ASM shortly. Drawing a screen is not horrible, but takes about 12 seconds. This is single threaded still, but I will be implementing multi-threading as soon as I get the drivers working. I hate to have to write my own text based gui, but I couldn't find anything that fit my needs close enough. I want font scaling because the simple borders control I have is not enough. Hats off to the guys at parallax for programming this font on the rom. It looks great.

Hey, thanks for the help! I have tried your latest test and still miserable failure. You mentioned that my displays may not have the same Power on and Reset values as yours(I believe we are using the same exact touchscreen module). How do I find out these values for my board and how do I adapt the code to address this? I think this may solve my troubles(My display doesn't seem to turn on or Reset ).
I mentioned those PORs because I am not setting every register on power on. You might want to try setting all the registers. I don't know enough to advise the correct values. With how forgiving these displays are, I wonder if you have a hardware issue. Did you connect Vcc to a good +5v? LCD Chip Select to ground and Write to +3.3? Does the backlight come on? Make sure LCD reset is 3v after power on. I have not needed reset, or used it other than making it high in the bootstrap.

Make sure LCD reset is 3v after power on. I have not needed reset, or used it other than making it high in the bootstrap.
Thanks for your patience. Yes I am using a good 5 volt for the VCC. I have put LCD CS to gnd and Write to 3.3 volt. Yes the Backlight turns in. But the LCD reset isn't 3V(tested with multimeter and got mere millivolts). My problem is that when I load the demo the backlight stays on but nothing comes up on the screen, don't know what to make of this though.
I sacrificed one of the displays by completely removing the SD socket and connecting wires to my own. Started with my own socket with lots of bypass caps and running the SD card off the propeller's 3V supply. First socket kept shorting the supply - who knows why but that one ended up in the bin. New socket. Moved the supply over to the local regulator. Removed first the 470uF, then the 22uF then the 0.1uF. No difference.
And then finally the answer. Bypassed the three 2k resistors.
So that is all you need to do. Remove those three resistors and replace with little wire links. Mine are not beautiful but they work fine. See attached photo. 10k pullups on the 4 lines. Oh and don't forget the card goes in upside down.
Tyler, your problem is the reset line. It must be high for the display to work. Otherwise the screen will just sit blank. You may be able to tie directly to 3v supply. I do not seem to need it, but results may vary.
Dr.A, I'm glad you got the card working. I will try again now that the rest of the hardware works.
Victory! Your were right joe my problem was the reset. I put it straight to the 3V just as you suggested and it worked perfectly. Now i'll move on to wiring touch recognition(hopefully it will take me less than a week ). Thanks for your help Joe and Dr. Acula(over on his thread).
@Dr. A im glad you solved the mystery of the sd card i'll definintly modify my board as you suggested and see if it works.
Awesome! I'm glad I could help. The touch input is very simple. DI, DO, Ck and CS. Write a byte, read 12. X-Y decoding looks to be decently easy.I will play with this in a couple days.
I have been thinking about freeing up the reset line since the screen doesn't seem to need it. I need to hook the CS line for the sd card back up and do some more tests. The sd cards I'm using (tried 3) might be the culprit. Now that everything else is working, it would be nice to have. I hope to have my sd breakout today or tomorrow, so that will give me something to test against as well.
I'm currently working out a couple aspects of the future menu design. I like using the propeller ROM font. It looks nice and has a comprehensive character set. I still need to write a few methods for the PropFont object, but this is what I have so far.
This is my PropFont object.
I'm sorry that I have not commented this code yet. I need to finish abstraction as well. It seems to run ok, other than being a bit slow. I have some ideas for optimization, but have not started working it out. I am convinced that using 2 cogs running Pasm will speed up display writes significantly. Before I can work on asm I need to finish the spin code. This includes a working character based gui. The current top object looks something like this.
That's the main portion of the code, some helper methods in the top object are

These are the basics. Once I get propfont finished, I'll re-write in asm which should speed up the display quite a bit. 12 seconds to display a blank screen is a bit too slow IMO. 4 sounds WAY more reasonable.
I've been working on the assembly program and had a lightbulb go off. I can save several instructions by adding a 10k pullup to the LCD write line. Instead of adding lcdwriteline to the data to be sent out, making pins = data, then pulling the write line low and back high again, flow will go make pins=data, mux lcdwrite*DIR* out, then back to input. I will be updating my hardware to this soon, but I'm writing without the update so I can test the difference this makes.
I will also be using a pullup on RS. This will save some code too.
edit,
Made hardware changes. I'm obviously doing something wrong in my ASM test. I don't know what now, I'll have to come back to this in a bit. Maybe someone can find my mistake, I'm burnt out at this point.

What you're doing here is running a huge loop full of nops. The nr modifier at the tail of your instructions stands for no result meaning the destination isn't affected. I don't think that's the idea here. So just remove them and let the insns do their default behaviour.
@Tyler, the colors are two bytes RRRRRGGG_GGGBBBBB so you get 5 levels for red and blue, and 6 levels for green. White is 11111111_11111111 which is hex FFFF
@Tyler, hex would be $FFFF. remember $ is Hex and hex is base 16. 0 - 9 and A thru F.
Thanks Kuroneko, I'll try again. Not very good @asm.
Thanks Joe! It worked perfectly(i need to read up on HEX im not familiar with it).
@Dr. Acula I bypassed the 2K resistors and the SD Card still didn't work. I tested my links they seemed fine, but my program still returned "Failed to Mount"(-1). Are there any other issues that may cause the sd not to work? I have formatted it to FAT-16 and it's a Lexar SDHC 4GB Sd card(if that helps with the diagnosis).
I have a working dat block. It writes a blank screen in a flash. I hope I can squeeze the character read and decode into the clock cycles wasted by the write loop. Very promising results. I'm glad I took the jump from spin to ASM. ASM is not that much harder, it's just it requires that much more though to making things work.
I hooked the sd card on my screen back up, but I haven't tested it yet. Now that spin code works, I'm going to investigate again. The hardware mods work great. Getting ASM working was top priority, now on to sd card!
*edit*
the question I have now is on cognew formatting..
is it?
cognew(@entry, @buffer)
or?
cognew(@entry,@@buffer)
A 50sec delay is usually an indicator that waitcnt just missed its target and is now waiting for a full wrap-around. Can you figure out where in your code it blocks (delay could be in an object)?
This is a little bit of code for those that can print a pixel but can't get an SD card working in order to display a font. Uses the internal propeller font which is inside the propeller chip.
PUB Propfont ' use propeller font in the rom for bootup messages when debugging sd cards

First thing, make sure you are using the same controller. If you are, it's most likely my code. I have had some bugs so. I changed hardware version, but the display is wired the same right now.

I am commenting code right now. I used to be in the habit of commenting as I wrote. I have been slacking off a bit.
I still have not been able to get my analog board to work. I will be switching back to my BS2 to test the control circuitry I added. The board was working with the BS2before I added the control circuitry. I'm hoping I'm just doing something wrong.
Found another wiring mistake. I wired DEV_SPI_ADD_LE to DEV_SPI_EN. I am correcting this now.
Other bugs found. Fixing those as well. I will be updating the final rev of ScreenTest shortly.

Hey, bonus. Tempting to order 2000 and see what happens.
6 hours to go before work stops and soldering time starts
Hey, thanks for the help! I have tried your latest test and still miserable failure. You mentioned that my displays may not have the same Power on and Reset values as yours(I believe we are using the same exact touchscreen module). How do I find out these values for my board and how do I adapt the code to address this? I think this may solve my troubles(My display doesn't seem to turn on or Reset
Thanks Again,
Tyler
Thanks for your patience. Yes I am using a good 5 volt for the VCC. I have put LCD CS to gnd and Write to 3.3 volt. Yes the Backlight turns in. But the LCD reset isn't 3V(tested with multimeter and got mere millivolts). My problem is that when I load the demo the backlight stays on but nothing comes up on the screen, don't know what to make of this though.
Thanks,
Tyler
I sacrificed one of the displays by completely removing the SD socket and connecting wires to my own. Started with my own socket with lots of bypass caps and running the SD card off the propeller's 3V supply. First socket kept shorting the supply - who knows why but that one ended up in the bin. New socket. Moved the supply over to the local regulator. Removed first the 470uF, then the 22uF then the 0.1uF. No difference.
And then finally the answer. Bypassed the three 2k resistors.
So that is all you need to do. Remove those three resistors and replace with little wire links. Mine are not beautiful but they work fine. See attached photo. 10k pullups on the 4 lines. Oh and don't forget the card goes in upside down.
Dr.A, I'm glad you got the card working. I will try again now that the rest of the hardware works.
@Dr. A im glad you solved the mystery of the sd card i'll definintly modify my board as you suggested and see if it works.
Thanks,
Tyler
I have been thinking about freeing up the reset line since the screen doesn't seem to need it. I need to hook the CS line for the sd card back up and do some more tests. The sd cards I'm using (tried 3) might be the culprit. Now that everything else is working, it would be nice to have. I hope to have my sd breakout today or tomorrow, so that will give me something to test against as well.
I'm currently working out a couple aspects of the future menu design. I like using the propeller ROM font. It looks nice and has a comprehensive character set. I still need to write a few methods for the PropFont object, but this is what I have so far.
This is my PropFont object.

I need to finish abstraction as well. It seems to run ok, other than being a bit slow. I have some ideas for optimization, but have not started working it out. I am convinced that using 2 cogs running Pasm will speed up display writes significantly. Before I can work on asm I need to finish the spin code. This includes a working character based gui.

This will save some code too.
edit,
Made hardware changes. I'm obviously doing something wrong in my ASM test. I don't know what now, I'll have to come back to this in a bit. Maybe someone can find my mistake, I'm burnt out at this point.

Thanks Joe! It worked perfectly(i need to read up on HEX im not familiar with it).
@Dr. Acula I bypassed the 2K resistors and the SD Card still didn't work. I tested my links they seemed fine, but my program still returned "Failed to Mount"(-1). Are there any other issues that may cause the sd not to work? I have formatted it to FAT-16 and it's a Lexar SDHC 4GB Sd card(if that helps with the diagnosis).
Thanks for your help,
Tyler

the question I have now is on cognew formatting..
