When you say: "The data has already been processed from the original wave file by the PC program."
-> you mean by your program that dumps the sound file to the memory chip or by the program that recorded/converted the sound? In other words, would the sound file (wave, 44KHz, 16 bits) I found in a game sound directory be ready to be stored in the memory chip? Can I transfer the wave file 'bit per bit' into a memory chip or does the file need to be modified to be used by the dac? I guess there is a header, a trailer, a checksum and stuff like this I should get rid of first. I will read the wave file specs...
The PC program converts from wave format to sequential bytes and sends to memory chip.
Must be modified.
PC program also adds CRC for 115k serial transfer.
I believe the PC program source code is included in my website download.
