serLCD library and LCD-14074 ROHS

Hello,

I’m trying to use a ESP32 with and LCD-14074 20X4 connected via I2C, and I can’t run any of the examples because I get the following error:

mismatched types ‘std::initializer_list<_Tp>’ and ‘unsigned char’

row = min(row, MAX_ROWS - 1); //row cannot be greater than max rows

Any ideas on how to solve this?

Thanks

Unfortunately it doesn’t look like the SerLCD library is compatible with the ESP32.

I’m afraid we don’t have a fix for that right now.

Could you tell me what alternatives do I have to use this LCD with the ESP32?

When I use wire.Print() it works, but it’s very buggy.

Thanks

Unless you write your own library or emulate what the library does with your own code, the only other thing I can think of would be to use something like an Uno or other ATmega328 based board rather than an ESP32.

I wish I had a better solution for you, but there isn’t much else that can be done.
