Description
Hello there and thank you so much for your great library and work. I want to start playing around with the ULP copro and as a first step, I want to get the blinky example getting to run. I am working with micropython 1.18 on Heltec Wifi Kit32. On this board, the onboard LED is on GPIO25, so I have changed the definition to:
#define RTCIO_GPIO25_CHANNEL 6
If I start the program it will run without an error and I still can see the print output changing from 1 to 0 and vice versa, but the LED doesn´t light. Could you give me a hint, of what I am doing wrong?
Thanks in advance and best regards,
Werner

Research direction
Start with the blinky example and the RTCIO_GPIO25_CHANNEL definition described in the report. Check how the Heltec Wifi Kit32 maps its onboard LED to GPIO25 and how that mapping is used by the ULP example; done means the LED visibly follows the changing 1/0 output.
