Within the reference design there is a adc_test() function that test the board by forcing the ADC to output a specific value or pattern. There is a write to the ADC(?) at the beginning of adc_test()
Xil_Out32(XPAR_AXI_ADC_2C_0_BASEADDR + 0x2C, 0);
and a similar write at the end of the test
Xil_Out32(XPAR_AXI_ADC_2C_0_BASEADDR + 0x2C,0x2);
These are not commented nor can I find what/where the 0x2C register is. The XPAR_AXI_ADC_2C_0_BASEADDR is address of the axi interfce to the adc channel 0 I assume.
Can anyone help?
