I saw this awesome video E-Paper + ESP8266 Tutorial - Easy Text & Images and got pursued to buy two 7.5" displays (black/white/red) - thought it would be easy to do on the particle photon (crawling down the rabbit hole).
My experience with Photon little (did manage to make an LCD display some stats from my database - success! ) and porting other libs into it is zero.
I got the e-Paper HAT module and connected it as follows
BUSY -> D2
RST -> D4
DC -> D3
CS -> D6
CLK -> D5
DIN -> D7
GND -> GND
3.3V -> 3.3V
(This is like what is being suggested in the README of GxEPD for ESP8266 NodeMCU except that CS is suggested to connect to D8 - which do not exist on a Particle Photon)
I did my best to create all the files needed. Tried to compile and fixed what I could.
- Created missing files
- Fixed nested paths to root level
- Changed some
transfer(x)- commented with
// PORT CODE
But now I have hit a wall
All of my code is to be found here:
ANY HELP WILL BE HIGHLY APPRECIATED!!!
BTW: Perhaps I should mention that the final goal is to make it display some images (citations and funny memes etc.) that I’ll upload to the web somewhere and do some processing so the photon can easily grab one of them.
