I have a strange problem and I couldn't find a solution for 1-2 month.
In my system I have a Tiva TM4C123GH6PM MCU and external 24 Bit ADC(MCP3919). My PWM pin generates 8MHz clock for ADC main clock. ADC conversion automatically starts with this clock.
My problem is that with software/hardware reset of MCU, my ADC readings sometimes goes wrong. It is like "fixed garbage value" comes from external ADC to me with SPI communication.
Only power off/on device solves problem!!!
As a result, there is a problem that occurs with software/hardware reset of MCU in run-time and the problem is solved with only power off/on device.
I don't know it is related with power-cycle issues sth. like this or not.
I really need your experiences with this issue.
