I’m developing a small communication device with Atmel AVR ATMega 2560. I use as IAR C compiler as development tool.
In my application I have very strict timing restrictions during serial communication, so I need that USART interrupt have to be ALLWAYS active.
Unfortunately RTOS during context switch disable interrut. This cause in my application lost or Rxed bytes or many jitter on Txed bytes.
It’s possible to keep interrupt active during context switch ?
Someone can help me and give me some directions about this issue ?
Thank you in advice
