I’ve got some code that needs to run every 2 minutes which seems simple enough. The problem seems that triggering a long running process from within a timer causes the timers to go wobbly? any suggestions.
My C knowledge is not that great so help me out with some basic ideas. The MCU is an Atmel Mega128L
The long running process is an http call through a Telit GSM device (through UART1), this works great on its own but needs to be run out of the main loop as it needs to monitor other processes.
I have been been told to set a flag within the interrupt and have those long-taking jobs done from the main routine, which checks for the flag perpetually, the task loop.
