    Pioneer baseboard with BLE Module - why is max ADC result 0x7FF in 12 bit mode?

    RoMa_4791621

      I've got the CY8KIT-042-BLE-A kit and have tried 2 example projects. Both yield a maximum ADC result of 0x7FF but seems to work fine between 0-0x7FF. Simplest example I used was PSoC4_ADC_with_Differential_PreAmplifier01 and using a single ended channel.

       

      I've got to be overlooking something simple but I've done nothing but spin wheels for hours. Here I've got adcVal[CHANNEL_4] tied to 3.3V supply. Tried both internal ref =1.024V and VDDA. no change, max ADC result is still 0x7FF.
