Hi Tarzan,
Good to hear that the software is now operating on your system.
Single conversion mode works but its operation is not apparent. If you open the interface window, select single conversion mode and write these values to the ADC, the ADC will perform a single conversion. Now, read back all the registers and the data register will have changed its value.
After performing a single conversion, the ADC goes into power-down mode. So, if you close the interface window and attempt to gather samples, the software will state that the ADC needs to be in continuous conversion mode. This is because the ADC has already performed the single conversion and is in power-down mode.
Regards,
Johnny
