I am attaching previous version (v0_2) of the example where I have been using eQADC_B, v0_3 has been changed to eQADC_A. You could combine it together.

There are 2 eQADC modules on this device, both consists of 2 ADC units => you may convert 4 channels in parallel, but it must be different channels.

Example codes you may find here, browse for eQADC:
