Hi, I'm using for a couple of years this library in a project write in platformio and stm32duino framework with a bluepill, and without the lcd.clear issue all the rest work good. I was using 1.2.4 version, now I want to update to last version 1.3.1 but it gives me this compiling errors:

As I see in LiquidCrystal_I2C.cpp you add support for ESP32 and add a VARIANT_ARDUINO_STM32 but platformio isn't taking this option, is taking the last option: bool LiquidCrystal_I2C::begin() without any variables so we have the error about this 3 indentifiers.
I add the #define VARIANT_ARDUINO_STM32 in my main.c but isn't working anyway.

Maybe for platformio we have to add more definitions, somebody can help me?

Hi,

Firstly, thank you a lot for this useful library. Nice work.
I have use a lot your library for different project, with good results.
But for my last project with relays, I have frequently freezing screen with STM32 Blue Pill.
And normal program still continues to work, so I think it coul be a loosing communication frame, so next comunication isn't understood by PCF8574 anymore.
Somebody with same problem? Any help will be thanksfull

I have a problem with hangs during startup or just after flashing my ESP8266. Is there any way to send command to "restart" PCF8574?

The lcd.begin(COLUMS, ROWS, LCD_5x8DOTS, D2, D1) != 1 but just after power cycle everything is OK. It is difficult to reproduce, but I have faced this problem three times on two different setups.

P.S. Maybe it is the same problem as #1

LiquidCrystal_I2C.cpp linea 765 if (Wire.endTransmission(true) == 0) return true; return false;

cambia por if (Wire.endTransmission(true) == 0) { return true; } return false;

Sorry but I didn't could run LCD with last changes, I thought that it was my mistake with the begin.lcd but I changed to the last STM32 example and isn't beginning, just the message through serial port:

And when compiling I have this versions:

Can you check the code please? I change library to version 1.2.4 and my code works great
