Classes

Module Contents

class machine.WDT.WDT(id=0, timeout=5000)

Create a WDT object and start it. The timeout must be given in milliseconds. Once it is running the timeout cannot be changed and the WDT cannot be stopped either.

Notes: On the esp8266 a timeout cannot be specified, it is determined by the underlying system. On rp2040 devices, the maximum timeout is 8388 ms.

feed() → None

Feed the WDT to prevent it from resetting the system. The application should place this call in a sensible place ensuring that the WDT is only fed after verifying that everything is functioning correctly.
