Hi,
it's me again :) . I think there is another bug in the F2802x Peripheral library. The function
ADC_setVoltRefSrc(myAdc, ADC_VoltageRefSrc_Ext);
does not set external voltage reference. It should set bit 3 (ADCREFSEL) in ADCCTL1 register but it sets bit 0 instead. Could you please check and eventually add it to the bug list ?
Library : C:\ti\controlSUITE\device_support\f2802x0\v230\
Best regards,
Jiri
