We have an important update to our TCD1304 project. After some extensive study using the FlexPWM for precisely controlled timing, we were able to arrive at 0.19% INL. This involves idling the CNVST signal to the ADC as a kind of virtual buffer for the reference voltage system and the way it interacts with the intermals of the ADC, and careful placement of the CNVST signal in time with respect to the operation of the new pixel transition and the internal operations of SAR engine in the ADC.
