If you do so, you'll see that this is a low-power Cortex M3 MCU with 64 KByte of flash memory that comes in a 64-pin LQFP package that'll operate in a temperature range between -40°C and 85°C. A command used for resetting this timer is intentionally left out in the main program loop, thus enabling it to win the time battle and cause the microcontroller to be reset. Currently we have official packages …. If your program uses a larger delay() which greater than threshold delay of watchdog timer, add reset function before that delay too. Time must be greater than the time required for program loop takes to come back again. However, higher sampling rates can be achieved by sacrificing the high-resolution. A microcontroller (also called μC or MCU) is an embedded computer chip that controls most of the electronic …. the Application Watchdog (done via FreeRTOS) works as documented.
