![]() I ended up adding 20 seconds after showFont and drawBitmap. Adding a bit more serial debugging, it was still updating one when sending the updates for the next bit. I did have problems with the example originally, it did not seem to be running the helloArduino and helloEpaper parts. G圎PD2_3C display(G圎PD2_420c(/*CS=A2*/ D8, /*DC=*/ D7, /*RST=*/ D6, /*BUSY=*/ D5)) įrom YouTube videos and running the particle example, I do think the buydisplay screens must be much slower at updating than the waveshare ones. Thank you both, it is now working I need need to go for the Workbench and not do web updates, but the serial console proved useful - sorry I should have included the full wiring. mapping suggestion from Waveshare SPI e-Paper to Particle Photon Display Library based on Demo Example from Good Display: Caution: these e-papers require 3.3V supply AND data lines! If you start from the repository version on GitHub, you find the examples for Particle on extras/Particle: ZinggJM/G圎PD2/blob/master/extras/Particle/examples/G圎PD2_ParticleExample/src/G圎PD2_ParticleExample.ino // Display Library example for SPI e-paper panels from Dalian Good Display and boards from Waveshare. Note that the examples for Arduino IDE (still) will not compile for Particle, because of different (automatic) additions for forward declarations for. Price: USD looks like you used a line from the example for the Arduino IDE, a line for ESP8266, e.g. I’m not sure what the SS bit is after CS.ī Red 4.2" inch e-Ink Display Module 400x300 for Arduino,Raspberry PiĮR-EPM042-1R is 4.2 inch e-paper (e-ink) display module,400x300 pixels with controller UC8159C,SPI interface,supports red white,black for arduino,raspberry pi. ![]() If I go with the 4.2", which is 400x300 resolution like the waveshare, do I just uncomment out the sections in the line below to give:? It is a 4 wire SPI, which I have connected as: I have managed to port their libraries over, but this library combined with Adafruit’s graphics library looks far better. I have a couple of epaper displays from (a 1.54" and a 4.2"), which seem similar to the waveshare devices but cheaper. Could anyone offer a quick bit of advice on getting started with these libraries? I’m finding the initialization part confusing. ![]()
