Formatting char arrays for USART transmission
Yes, I've completely changed that section now. I've also changed sines to just a double array, and let the sinepointer do the pointing for the call to sinescalc. Simply a LOT...

Formatting char arrays for USART transmission
I want it to be ASCII-formatted so that terminals can use it, not just the raw binary data.   The reason I was using strcat() was to add the words onto the value, to try and...

FPGA development
Yeah, nobody seems to be able to answer the question -- "How do you program an Atmel FPGA?" Such a simple question! But seriously -- Xilinx has ISE and Vivado, Altera has Quartus...

FPGA development
At this point, basically just learning how to spin a basic design using Verilog. I actually managed to get a free sample of the AT40K40AL, which sells on DigiKey for about $75. I'...
