Hi ZinggJM, Is there any way to change the below mapping in code // mapping of Waveshare e-Paper ESP8266 Driver Board // BUSY -> GPIO16, RST -> GPIO5, DC -> GPIO4, CS -> GPIO15, CLK -> GPIO14, DIN -> GPIO13, GND -> GND, 3.3V -> 3.3V I need to change DC to some other pin. I am using pin 2 as SCL, …

Shrzpk found the place to ask this question. This is my answer there: @Shrzpk, Good you found the right place to ask this question; you have a strange "Particle". Waveshare chose to connect the DC line to the e-paper display to pin D4 of the ESP8266. There is no chance to modify this in SW; you …

Welcome. What particle product are you using ? If you post some code we can help. The information above is insufficient to even understand the problem?

#include <SparkFunBQ27441.h> #include <Wire.h> // mapping suggestion from Waveshare SPI e-Paper to Wemos D1 mini // BUSY -> D2, RST -> D4, DC -> D3, CS -> D8, CLK -> D5, DIN -> D7, GND -> GND, 3.3V -> 3.3V // mapping suggestion from Waveshare SPI e-Paper to generic ESP8266 // BUSY -> GPIO4, RST -> …

Thanks - when you past code please click </> first and then paste. This make it much easier to read. Secondly, what particle product are you using ?

[image] shanevanj: what particle product are you using ? To expand on @shanevanj 's repeated request to tell us what platform you are talking about: This is a forum dedicated to Particle devices - it's not a general Arduino or Espressif forum.

As I explained in my last comment and repeating here again ESP-12e ( Waveshare e-paper ESP8266 driver board ) Sparkfun babysitter battery fuel lipo 5000mAh battery waveshare e-paper 7.5" 3C This is related to Arduino project and I have read some comments from ZinggJM(author of GXEpd2). Is he sti…

Since this is not targeting a Particle device your best chances are either on an Espressif forum or on @ZinggJM's GitHub repo - IIRC he said he just added Particle to his supported platforms list but won't actually invest much more time on Particle.
