Cannot Blink Built-in LED with Basic Example Code #17

Closed baqwas closed 4 years ago

baqwas commented 4 years ago

Upload displays Done Saving, on-board LED blinks during process but no steady blink that occurs when code is running. Still cannot blink built-in LED (pin # 13?). Is there a checklist that I can follow to ensure that I have not omitted any step?

Thanks.

Output pane is hung with:

There is nothing visible occurring after the last line is posted in the Output pane.

There should be some documentation somewhere but somehow owing to my inexperience I don't know where to find it. Please help me. I would like to test the Sipeed Maixduino board with beginner's examples.

Kind regards.

Try chaning the Baudrate to: 115200

@feldim2425 Thx for the suggestion. Been there, done that before posting my issue. I have suspended the Arduino effort and will try the MicroPython approach given that @loboris is guiding me. Kind regards.

hi @baqwas ，

I replied to your this issus at https://github.com/sipeed/Maixduino/issues/36#issuecomment-516265109. If you want to use blink, please use serial tx pin led at pin 1 ,it is the only LED that can be lit onboard.
