I tried to run this PCF8574 exampleon ESP32S board but failed to compile the code, is it possible to use this library with ESP32? if yes, kindly provide simple example code.
I tried different initialization,
B4X:
pcf.Initialize(0x20,pcf.I2C_Wire2) 'also tried Wire and Wire1
pcf.begin(21,22,0xFF) 'ESP I2C pins
