I am very new to using a RTOS. I am investigating a possibility of using a FreeRTOS for the future projects in our company as it has been recommended to us.
Having almost fully read the "Using Free RTOS…" book I have got a question for you. If in one of our projects we had to process a very fast interrupt (by fast I mean that it could occur very frequently) and we also wanted to still use the RTOS API functions it would have to be defined at a priority lower than the Kernel. This means that jitter will be intoduced to the ISR processing. Can anybody tell me what this jitter is going to be on a PIC32 processor (in clock cycles)?
I am just trying to evaluate how likely it is that we would have to configure that interrupt at higher priority than the Kernel and not use the API.
Thank you in advance,
