I have two MCU's (the parts are here and this is what I have to work with)
PIC18F4550:
USB connection to host
Several connections to I/O
PIC18F2550
Scanner Algorithm for LED matrix
The computer is to send packets (containing an array of numerical values) to the 4550 through USB, get forwarded along to the 2550, where the data is interpreted and the matrix is thereby driven. It will comprise two 4x5 matrices, currently one.
the plan, get the two chips to talk together by USART, SPI or I2C. I'm very close with USART, not with the others...
I am wondering if you might have some code I could use or convert or something that would help me along.
I used this tutorial to get the USB capability working...
