Hello all
I am trying to develop a DIY USB audio DAC to go with my android phone and in the second stage of this project I want to interface it with relay boards (to switch things on/off etc). I can find few existing projects that did the USB DAC but they do not include any GPIO (general purpose I/O).
I know that there are a few Holtek Microcontrollers that I could use, but the problem with Holtek is that there is almost no tech support. I have no clue how to program the MCU etc.
Can you guys suggest me on which chip I should use for the purpose ?
I need the following:
Hardware implemented USB DAC for audio output
GPIO
SPI interface
easily programmable
Good documentation/tech support etc.
I am new to this forum. Is there an existing thread that could help me with this ? Please post the link in your reply.
Feel free to ask me any questions you might have.
Thanks in advance.
