1 year ago The changes I've made in the code are:
- main.cpp: uncomment line 54: #include "./LiquidCrystal_I2C.h"
- open_evse.h: comment line 238 //#define DEFAULT_LCD_BKL_TYPE BKL_TYPE_RGB and uncomment line 239 #define DEFAULT_LCD_BKL_TYPE BKL_TYPE_MONO. Uncomment line 247 #define I2CLCD_PCF8574 which defines I2CLCD and undefines RGBLCD.
The LCD and interface module I'm using is https://www.az-delivery.de/en/products/bundlelcd-schnittstelle I don't know if i'm missing something or it's just that the interface module is not supported. In that case, which LCDs/I2C interface modules could I use for this project? Thank you very much, Pablo

Hello lincomatic, First of all, thank you for your help and your work on this project. My issue is regarding the installation of a monochrome LCD in the system. I have substituted the OpenEVSE RGB LCD for a monochrome LCD with a PCF8574 interface module. So far, the LCD powers on with a white screen and blinks everytime I load the firmware or plug the board, but text won't show up in the screen. I think communication is fine because if I change the LCD_I2C_ADDR, the screen won't blink everytime I load the firmware. So address 0x27 seems to be the correct address. The changes I've made in the code are:
