Hello everyone, I have recently purchased one of those cool RGB matrix controllers from Sparkfun, and am just beginning to full understand how to work it . Because of it's onboard SPI functionality, I figured I'd control it with that. I only have 2 uC's with SPI capablity (16F88 and ATtiny13) and hopefully will use the PIC, for which I have better programming equipment. However, is this possible to have a PIC control an AVR via SPI? Also, if any of you have any sample code/schematics or links they would be very much appreciated, as I'm just a highschool student introducing myself to this new hobby.
SPI is horridly easy to bit-bang. Any microcontroller can handle it, or you can use the PICs SSP (read teh datasheet) module to handle it for you. Did you see the "Example Code" Link on the page of the product you bought? http://www.sparkfun.com/datasheets/Components/LED_MATRIX_CODE.zip What compiler are you using?
Sorry for the late reply, I was on vacation. Yes, I have checked out the example code, and am going to use the PIC16F88, however the example code is in C (with which I have no familiarity). I plan to use assembly. I was wondering if anyone had any example code or links.
Go grab the CC5x Compiler. The free version is good for up to 1k of code, and you can link code together outside of the compiler if you need more space.
