Yes, all of the music is a single wave file and has been premixed and is ready to go. I finally found a very reliable way to etch my boards, which sucks this close to the deadline, but it works very very well. I found that using a course grit sandpaper works better than trying to make the surface extremely smooth. The traces stick bettrer. Also found that if I don't worry about getting all of the paper out between traces before etching and then take it out after it has etched for a couple minutes, the paper comes off without a problem. I did a board last night with 100% traces in tact. Still waiting on the replacement connectors to show up for the igniters to connect to. If they don't show up, I don't know what we'll do.
We are very behind on the schedule so I doubt we will have a full use of all of the slaves, but I will keep plugging away at them and get done what we can. At least there should be a working ignition system.
Do the caps on the audio out have to be those values? I was going to hit my brother up for some of that size, but he left on a trip till the 1st and I'm not sure where to get them from quickly.
They do not have to be those exact values but they should be close.
The 10nF (.01uF) filter the pulses. If you make them smaller the high frequency noise will increase and the bass will decrease. If you make them larger the high frequencies are reduced and the bass increased.
The 1uF also affect the bass. Better to make them larger rather than smaller but anything from 0.47uF to 10uF should be ok.
they are extremely common values though and you should have no trouble finding them in any electronics store that sells parts.

Is getting the code to the prop mod as simple as copying it and the wave file to the sd card and inserting it or did I miss something there.
How big of card will the prop mod handle, 4-8gb? ·
The propmod is programmed through header. Sd card can be 2gb or less with code we are using. e

Ok, what do I need to program the propmod? I picked up a couple of 2gb micro SD's. So once the propmod is programmed, does it need to be programmed every time we use it or will it pull off the SD card from then on?
With uSD on top you place the prop plug on the programing header with badge down.

Did I miss something? what programming header are we talking about? The original Prop Dev board I bought had USB on it, is there something else I need to buy or build?
You need to build the serial adapter in proppeler manual or buy propplug which is a usb programmer

chaosgk, here is the latest version using the '595 chips for selecting the slaves.
It should select slave 1 and activate relays 24 and 56,
then slave 2 relays 23 and 56,
slave 3, relays 22 and 56 ....etc
finally slave 15 relays 10 and 56
Sorry about the delay completing the software. I have been extremely busy up to now, and working on it a bit here and a bit there makes it go even slower. Also, my hardware is not the same as yours which makes it harder still. I have taken Thursday to Sunday off to concentrate on finishing everything. From my end it should just be the timing and push buttons left.
PS - for the moment I am using a keyboard with the enter key for start/pause and esc for reset.
I may have time this weekend to write a boot loader that can load the eeprom image from the usd card but you will need to mail propmod to someone with propclip or make serial circuit to load the boot loader on.

Awesome Kurt, you've gone so far out of your way for this, I can't even begin to thank you enough. Anyway, I've been busy with building the actual pyro's because it seems my partners can't somehow pick up the basics of making the stars and I have to babysit them on everything. It's our 2nd year of building and they should know this stuff. I have other guys coming out this weekend that did a lot of the building with me last year so hopefully everyone will start picking up their own parts so I can focus just on the firing system and not worry about anything else. I have Tuesday through the 4th off so I should be able to focus on this stuff.
I looked up the manual for the serial adapter, it appears to be just a simple connection of the correct lines off a serial cable to the correct pins on the prop, the page I saw used 4 wires I think? correct me if i'm wrong or post a simple pinout of what goes where and I'll whip something up.
You'd think that you could tell a couple of 40 year old men that the mixtures need to be wet to the consitency of modeling clay or playdough or just clumpy like damp dirt and they could figure out what that means. They also can't seem to figure out that it is easier to mix up a batch of chemicals and seperate a few ounces to use as spare if they over wet something so they don't have to measure out another 5 or 6 different chemicals again to add to it. AAAAAAGGHHH.
I'm tired and need to go to bed. I'm going to feel like a real *** if you all have gone to so much trouble for me and we don't get it ready in time or something goes wrong and none of it works because of something I did or didn't do in time.
I only need one good 20 hour day to get the electronics functional and then I can focus on the other stuff, which I have wasted that much time holding their hands or doing things that they didn't get done.
The prop can't by any chance slow down time can it, that would be a great spin program if it could, maybe give me an extra two weeks.
When looking at the propmodule with the sd card on top and the prograing header facing you pins are from left to right:
vss, /res, tx, rx

chaosgk, I have uploaded V 0.04 to the earlier post.
It should select slave 1, pause for about 1 second and activate relays 24 and 56,
then slave 2 relays 23 and 56,
slave 3, relays 22 and 56 ....etc
finally slave 15 relays 10 and 56, and stop at this point.
Hope you have more than one slave ready. If you need more time to check the slaves you can change the "waitcnt (8_000_000 + cnt)" in the "wait_for_time" subroutine.
mctrivia, I have added "begin_music", "pause_music", and "continue_music" subroutines to the program. Can you add the wave player and the calls for those functions in and send the result back to me. I have 2 questions for you.
1 is the handling of the SD card done directly by the music object?
2 would you have time to write and test the start/pause and reset button routines?
Since I don't have the same hardware setup either of you do getting everything working could be difficult. Any ideas on how to proceed?
I am going to concentrate on a PASM program that uses a cog to provide accurate millisecond timing and leave the music and button stuff for you guys. If we are pressed for time the keyboard can be used for the moment.
If you get newest code I wrote it contains everything. All you need is initialize and add play pause calls. Look for the most resent zip

We have to DJ a wedding·tonight, but my guys are coming out after we are done and will probably pull an all nighter. I hope to have at least one slave tested by morning, if that one does what it needs to, I'll be printing the slave boards in mass and getting everyone I know to start soldering. ·

Are those 2n3906 and 3904 amplifiers necessary? I need to try and make this from parts I can find around here and I have everything else except those unless I can find them in something else.
they are necisary because the voltage on the serail port is no where near the right voltage for the propeller. They are extremely common parts and you are bound to find them. They do not have to be those exact part numbers. any similar NPN and PNP transistor should work. I would recomend buying the propplug it makes things so much easier.
hope to finish it this weekend so you may be able to just mail the module to a forum member near by who could program it for you.

Ok, how about this, is it possible to have a prop program a prop? Remember, I do have my USB propeller dev board, can I connect it to that somehow and have it program the prop mod? It has all those IO pins, it should be good for something right?
Yes. Connect pins 30,31,reset and vss together between two boards with short wires. If you connect power to module only should be able to load boot loader on. After that you can remove connections and load nee code via usd
May want to ask in prop formula if it will work before trying.
I will send you loader when done it
