Blinky example not working #71

Closed Raunak-Singh-Inventor closed 2 years ago

Raunak-Singh-Inventor commented 2 years ago

I ran cargo espflash --example blinky --release /dev/ttyUSB0.

But the LED on Pin 13 is not blinking. Here is the output from espmonitor:

Any help would be appreciated.

The blinky example is using GPIO2 instead of the more common GPIO13, as seen here:
https://github.com/esp-rs/esp32-hal/blob/master/examples/blinky.rs#L31

Changing this line should hopefully resolve the issue.

Thanks for the help. It worked.

Suggest that we include this instructions in the README.md on the main page. Should I create a pull request if its okay?
