Wemos d1 mini pin mapping #1243

Closed danielmawhirter closed 8 years ago

danielmawhirter commented 8 years ago

(using 2.0.0 package manager version) The Wemos D1 mini's pins do not map to arduino pin numbers accurately. Here is the mapping as I have found it so far (using pinmode(), digitalWrite()'s, and a mega for analogRead()'s): normal status: d0=low, d1=high, d2=low, d3=high, d4=high, d5=high, d6=high, d7=high, d8=low After running the test with "10" pin d1 appears to have become normally low. Not a clue why, but I have eliminated those "d1 low" results below. arduino pin -> result/connection

0 -> d3 1 -> nc 2 -> d4 = led 3 -> nc 4 -> d2 5 -> d1 6 -> watchdog(4) reset 7 -> watchdog(4) reset 8 -> watchdog(4) reset 9 -> watchdog(4) reset 10 -> nc 11 -> watchdog(4) reset 12 -> d7 low, d6 sporadic 13 -> d0 high, d7 sporadic 14 -> d0 high, d6 low, d7 low, d5 sporadic 15 -> d0 high, d8 sporadic 16 -> d0 17 -> nc 18 -> nc 19 -> nc 20 -> stack trace and pin-based(2) reset 21 -> stack trace and watchdog(4) reset 22 -> stack trace and watchdog(4) reset 23 -> stack trace and watchdog(4) reset 24 -> nc 25 -> nc 26 -> nc 27 -> nc 28 -> nc 29 -> nc

Wemos D1 mini pin mapping is available here: https://github.com/esp8266/Arduino/blob/master/variants/d1_mini/pins_arduino.h#L49-L61 You should be able to use D0 – D10, D13 identifiers in your sketch.

So it is, I was mistakenly trying the lowercase variants and fell back to raw numbers. Thank you for your help!

Thanks, glad to see more documentation and shields coming up!

Sorry, mate. You’re heavily off-topic.

However, quick Google search for WM8731 library does it:

question was actually for WEMOS need an audio codec library compatible with wemos D1 mini...
