work on best low cost mp3 player for rockbox
bonusbartus:
Maybe I can help out.
I do have lot of resources at the company I work for, so I could ask around and find some chips for you. I would love to get a new rockbox player to be developed... still on my H340 now.
Can someone give me the requirements for a rockbox'able soc?
wodz:
1) 32bit 100MHz+ reasonable architecture for which there is free compiler
2) external memory interface so you can build system with 4MB+ of ram
3) I2S block or optionaly integrated codec (DAC+output amplifier)
4) serial or parallel lcd interface
5) sd interface for mass storage
6) serial/parallel flash interface for boot memory
7) Documentation available
8) For this particular application - CHEAP
bonusbartus:
take a look at this STM product range, as far as I can tell they have everything you need.
