看门狗,又叫 watchdog timer,是一个定时器电路, 一般有一个输入,叫喂狗(kicking the dog or service the dog),一个输出到MCU的RST端,MCU正常工作的时候,每隔一端时间输出一个信号到喂狗端,给 WDT清零,如果超过规定的时间不喂狗(一般在程序跑飞时),WDT 定时超过,就会给出一个复位信号到MCU,是MCU复...

Three letters jumped out at me: WDT, the watchdog timer. Something in this example sketch is taking too long to do its thing, causing the system to believe it has locked up and needs a reset to recover. One unusual aspect ofssd1305testcode is that all work live insetup()leaving an e...

The watchdog timer can only reset (use the RTC and PIT for low power timed interrupts). There are wrapper functions around the software and WDT reset methods in DxCore.hSee the Reset and Watchdog (WDT) Reference and The core-auxiliary library, DxCore...
4 GPIOs just like Arduino Nano GPIOs. ( only 3 if you use the Reset function ). 1 KBytes Flash memory, 32 bytes SRAM. SPI bus and I2C Bus. 16 bit timer with 2 output compare and 1 input capture register for 2 PWM channels. Watchdog timer. 4 s...
The window is an option to keep from getting stuck in a tight loop that you can't exit, but which includes a watchdog reset. An attempt to reset the watchdog timer too soon (before window time has passed after the last time you executed WDR) will also trigger the watchdog to reset ...
