Pathetic Propeller Program Please!

Vaati · 2009-05-07 18:45

I need a small pathetic program to ensure that my propeller works.· I looked in the obex but all of those are too complex for a simple test.· I have no clue how to use the prop either; I keep on typing in commands like "HIGH 2, DEBUG CLS" because I've used the BS2 for so long!·

··Also, could someone explain the differences/similarities of ASM, Spin, and whatever else the prop can be programmed with.

Thanks.·

What is your platform? Demo board, PDB, or hand-wired on a breadboard? Can you attach an LED and resistor to one of the pins?

ProcessingData... · 2009-05-07 18:53

Try this:

Var
long Index
Pub Blink
Dira[noparse][[/noparse]0..32]~~
Repeat 2
Repeat Index from 0 to 32
!Outa[noparse][[/noparse]Index]
waitcnt(clkfreq/2 + cnt)

This program will turn all of the pins on one by one waiting a half second in between, then turn them off the same way.(on a working propeller [noparse];)[/noparse]

I also have a prop chip that will run this, but will not run any video programs, so try running one of those too. [noparse]:)[/noparse]

Okay, well I have it on the boss board.... Check out the "troubleshooting the propeller chip" forum for a pic of it on the boss board. One thing is that I did get a prop chip that works instead of that broken one discussed.

@ProcessingData... So do you have a simple prop hookup for a video program...? I just want simple programs so I can actually learn SPIN instead of copying and pasting bits of other people's code without understanding any of it...

One more thing--- Do I select load RAM or load EEPROM to run that sample test? [noparse][[/noparse]I must be sounding stupid asking all these pathetic prop quesitons....]

thanks.

You can load a demo VGA program onto it, and then verify that pin 16 turns on at least. I understand about not wanting to cut and paste

, that's what·I did until the day when·I FINALLY figured it out, and could use it instead of the STAMP.·

[noparse][[/noparse]edit: Load to ram or eeprom. ram is erased after the program runs, so it will only run once. If you load to EEPROM, the chip will run it again if you push the reset button. The basic stamp always loads to eeprom, the propeller gives you the option.

First step - download the propeller manual! start with SPIN, see how things work and go from there. For the stuff I do, I usually do control structures in SPIN and time sensitive stuff in PASM. SPIN's also a lot easier to debug (for me), and develop in, so I prefer spin unless I need the speed.

Generally, when you develop, you load your program to RAM, test, and revise. When you're done, load to eeprom. If you've setup the video DAC on the boss board, just load the TV graphics demo (it's one of the demo files in the prop tool).

Awesome! I think I'll use ram for now as I'm learning the ins and outs of the propeller (no pun intended

) but the other reason is that I don't have a reset button... I had better add one... but where and how would I do so?

Thanks.

Vaati,

The program posted by ProcessingData wont work as is, since the formatting was lost in posting.· The Propeller Tool uses indenting to denote program blocks for things like repeat loops.· The code should look more like this:

Var
  long Index

Pub Blink
  Dira[noparse][[/noparse]0..32]~~
  Repeat 2
    Repeat Index from 0 to 32
      !Outa[noparse][[/noparse]Index]
      waitcnt(clkfreq/2 + cnt)

I don't have a prop in front of me, but that looks like it should work.· [noparse]:)[/noparse]

You can run it either from RAM or from EEPROM.· Compiling to EEPROM means it'll still be there after you power the Prop off and back on again.· Compiling to RAM means it'll only be there until you lose power.

When in doubt, read the manual. Also look at what others have successfully done before. In particular, there are schematics available from the Propeller downloads page for the Demo Board and the Protoboard. The Demo Board demonstrates all sorts of circuits ... for VGA, TV, keyboard, mouse, DAC for audio, ADC for a microphone, reset buttons, EEPROMs, power supplies. That's why it's a demo board.

QuattroRS4 · 2009-05-07 19:39

Vaati,
Attached are some images - showing the required connections for VGA and TV .... as per demo board ..··but like the others have said - start with the simple examples and work up from there ..

Regards,
John Twomey

For reset, just bring RESn (M13) to ground. I don't usually use a reset button - when you do a load to ram, it resets the prop anyway.

Okay, it compiled and everything.... After selecting "Run-Compile Current > Load RAM" I hooked up an LED to one of the I/O pins and nothing seemed to happen... Why can't there just be a button that says RUN like the Basic Stamp editor?

Vaati,

That's fine.. However you may want to repeat aq test for longer to ensure all is well ..

try this ..

Pub Blink
  Dira[noparse][[/noparse]0]~~
  Repeat 
      !Outa[noparse][[/noparse]0]
      waitcnt(clkfreq/2 + cnt)

Connect to 'P0' ensure correct LED orientation and appropriate resistor in series ..

EDIT: Vaati - please NoteThis will only toggle 'P0' !

Regards,

John

Woohooo!! It worked! I used my buzzer instead of an LED so I wouldn't have to be staring at the circuit! Okay, now that I know this works, I need to know how to do a simple TV output. Does anyone have a bit of code they can post on how to just display, "hello world!" on a tv in order to test the port?

Thanks.

I like to use a program that outputs data to a terminal in order to determine if the chip is working okay.

QuattroRS4 · 2009-05-07 20:18

CON

  _clkmode = xtal1 + pll16x
  _xinfreq = 5_000_000


OBJ

  text : "tv_text"
  

PUB start 
  'start term
  text.start(12)
  text.str(string(13,"Hello World ... This is Vaati",13))

Vaati - this assumes that you have a 5MHz crystal on your board ..

John

Vaati,
······· You are 'moving on' too quickly .. there are loads of examples included with the IDE .. you will have to work through them .. It doesn't happen overnight ..

I have attached a spin something that gives you tv text and sound ! ...enjoy

Oh wow. Thanks a lot for your code and help. I agree, I am kinda moving on too fast, but it is so I can check to see if all the ports work.

Thanks again.

Vaati,
I detect a bit of excitement - when you see results ! .. believe me we all felt that way .. but it would help to get a better understanding of the basics first.. Lots of people have great apps written .. SDCard,I2C,Graphics and Wav players etc.. All in good time .. enjoy..
