Posted on March 09, 2011 at 11:23Hello together,
I'm creating an application, which communicates with a mobile phone over UART. Sometimes an error appears and the answer of the mobile phone doesn't reach the MCU. So the MCU is stuck in a loop. ( while(1) ) . For this reason I want to add a watchdog, which resets the MCU. The problem is, that the longest watchdog reset time is about 1s, but sometimes the answer of the mobile phone comes with a delay of more than one second. Has anybody of you an idea, how I can use a watchdog with a longer reset time? Or maybe a total different idea?
Thanks for your help
Klaus
