Hello,
I would like to start a new project, my idea is this: an acquisition system based on pic, maybe pic32 but not necessarily, sampling freq. 100kHz, 24 bit, streaming data to tcp/ip client. Number of channels: as much as possible compatible with bandwith.
Few years ago I made a pic32 based board that performs a playback of a wav file from a SD card, using 16 bit dac (1 channel) at a datarate of about 384kHz and it is working well, so I expect I can have a similar datarate in the opposite direction.
However, I do not know how far I can push the system, and if an fpga could improve speed (which I have to learn how to program). How the fpga and dma could help to improve datarate?
Could you suggest any reading (app notes, etc)?
Thanks
