Description
The examples are very good, but I wanted to use another size: 5.83 inch b/w/r.
This size can not been used with the standard-RAM. There was an program exception.
But now are many boards with PSRAM available. i.e. ESP32S3-supermini
Changes:
- select ESP32s3dev at Arduino and enable PSRAM - now there is enough RAM available.
- alter the GPIO (restriction: I use a ESP32S3-supermini. There are only 13 GPIO available)
- I use the Waveshare "Universal e-Paper Raw Panel Driver HAT". There is an extra-Pin PWR. It must set to High.
#define EPD_PWR and activate in two places - For the use of the red color I defined "GxEPD_COLOR". (line 76) Here can you set the color to red, black or yellow (if available).
some interesting elements are changed from EPD_BLACK to EPD_COLOR. - the variables BUILTIN_LED and BATTERY were defined at the upper section.
- because of the missing argument color at "drawString" I duplicated the function to "drawStringColored". Add the argument color to the function would be a strong change at now.
- Fields selected and coordinates changed.
the program and the picture are added.
