Working on debugging last week's weird results for the ADC-DAC loopback test for channels 14 and 15. With DAC output channels 12-15 connected to ADC input channels 12-15: tried setting matrix coefficients for channels 12-15 to 1, and as with last week's results, DAC is outputting as expected for all three channels and ADC is not reading in the signal (hovering around -4,-5) for channels 14 and 15. Channels 12 and 13 still reading in correctly. Tried switching DAC output plug into channels 0-3, with ADC input plugged into channels 12-15, and all input/output signals were reading correctly. Then switched to plugging in DAC output to channels 12-15 and ADC input to channels 0-3, and saw that channels 0-3 were only able to receive the first two ADC input values. This shows that channels 12-15 are capable of receiving the correct inputs from other channels, but are failing to produce outputs for channels 14 and 15. |
