I am currently trying to use a Diymall 0.96 inch OLED display with my Particle Photon with I2C communication, but the library example for the Adafruit_GFX does not seem to be working. This is the compile error that I am receiving, and I can’t seem to understand what’s going on. I am only using one library, the SSD1306 library, and I’ve #included it correctly (to my knowledge). I’ve been looking online for a fix, but I’m not finding one immediately. Could someone help me out? A lot of the guides I have found have been for SPI (https://github.com/pkourany/Adafruit_SSD1306), so this is a tough one.
This actually is not a problem of
pgm_read_byte which only produces a warning (would still build).
The actual error revolves around the redeclaration of
Just remove/rename the function and it will build.
A forum search would have given you this (which also applies to I2C, since it’s basically the same sample, just different interface)
Adafruit SSD1306 [SOLVED]
Thank you ScruffR! This worked immediately. Happy Thanksgiving, as well.
Glad to hear that
I altered the topic title accordingly
