Welcome to the FreeDSP-FreeDSP_SMD_AB wiki!
FreeDSP Classic SMD A/B is a simple 2-in 4-out ADAU1701 Audio DSP board. This board was intended to be used with Analog Devices SigmaStudio software and USBi programmer.
Detailed information will be available from my web page. https://cyberpithilo.web.fc2.com/audio/freedsp/index.html#SMD_AB
This hardware design uses MP10(LRCK) for a negative power supply switching clock. So you need to set MP10 as an output of I2S LRCK anyway. This negative power supply was used for un-muting audio output signals.
