Hi MT, Thanks for the confirmation. It is troubling to hear that the SPI lines are that sensitive - we do want our customers to have the ability to monitor the SPI transactions and learn how it works....

Hi Ryan, I cannot monitor the CS line with a scope. The EVM does not like that. D2 or D1 goes OFF and a reset of either the processor or the ADC causes D1 and D2 to go OFF and D3 to turn RED. However,...
