I want to connect a LCD 1x9 to my esp32. I'm using an olimex board and olimex UEXT lcd1x9 display (sda=13 scl=16, address=56)
en I2Cscan shows me the lcd on address 56
I can't find an example how i can get this working.
i changed conf0.json:
in the init.js i have this
I2C.write(myI2C, ?, ?,1,true);
but what do i have to fill in to send characters to the LCD display?
how can i for example clear the screen, how can i turn on backlight, how to write ASCII to the lcd....
any help or example is welcome.
Thanks a lot
