- Test points - Multiple connections test points ADC/DAC, power supply, etc.
- Based on XMOS USB AUDIO 2.0 MC Reference Design
I encountted a problem we I run the .xe on the board: assertion "PLL_REGRD(0x03) == 0x07" failed: file ".././src/pll/pll.xc", line 47 Could you please provide the source code for the XMOC processor?
