Running NmraDcc on ESP8266 #64

Closed pelestedt closed 1 year ago

pelestedt commented 1 year ago

According to the Arduino IDE, when installing NmraDcc, the package supports ESP8266. Now trying to run on an ESP8266, Lolin Wemos D1R2, we fail to get any DCC messages decoded. The program and shield works fine on an UNO. Can you assist?

Yes, but I need a bit more information to be helpful as works on a UNO but not on an ESP8266 isn’t particularly helpful… ;)

Can you please answer the following questions:

Hi Alex,

Thanks for your quick response. I have done the "shield" I am using myself and it has a 10k pullup on the I/O pin. I have done a board in KiCad. I can send you the drawing if you want.

I have used your example files to test (changing the I/O pins to Dn first)

What I think you suspect and I believe I have now confirmed is that I use the only GPIO on the ESP8266 that does not support interrupt, D0.

Searching on internet gives mixed answers. Some say all GPIO support interrupt other that all except D0 (GPIO16) does. I will change to D1 and test. I will let you know the outcome of that.

Thanks again for your support and hinting me in the right (hopefully) direction.

Best regards Peter Elestedt

@pelestedt Did using a different pin to D0 resolve your issue?

pelestedt commented 1 year ago

Hi! Yes that solved it!
