TWR-KV46F150M -> driver Example -> cadc -> cadc_dual_parallel_conversion
It uses 4 diffrancial pair of ADC so there should be 8 pins configured..
why there is no configration related to ADC_CH6 & ADC_CH7...??
I suggest using the config tool to active that ADC channel. In the pin_mux.c is the configuration of the pin you selected in the config tool. Did you use the tool? If you need more information please let me know.
