How to specifying SCL and SDA.

  • arduino core for esp32:
    Wire.setPins(int sdaPin, int sclPin);
    i2cuart.begin(baudrate_A, baudrate_B);

  • arduino core for esp8266:
    Can not.

  • atmega:
    #define SDA_PORT PORTD
    #define SDA_PIN SDA
    #define SCL_PORT PORTD
    #define SCL_PIN SCL
    #include <SoftI2CMaster.h>
    #include <SoftWire.h>
    SoftWire Wire = SoftWire();
    i2cuart.begin(baudrate_A, baudrate_B);

  • Arduino core support for STM32 based boards:
    Wire.setSCL(SCL);
    Wire.setSDA(SDA);
    i2cuart.begin(baudrate_A, baudrate_B);

  • Arduino Core for Nordic Semiconductor nRF5 based boards:
    Wire.setPins(int sdaPin, int sclPin);
    i2cuart.begin(baudrate_A, baudrate_B);

Wire.setPins(int sdaPin, int sclPin); not working on ESP32 (error while compiling: 'class TwoWire' has no member named 'setPins').

This is not a problem with this library.

Is this library supports SC16IS762 ?

@mysticrnd

The SC16IS762 differs from the SC16IS752 in that it supports SPI clock speeds up to 15 Mbit/s instead of the 4 Mbit/s supported by the SC16IS752, and in that it supports IrDA SIR up to 1.152 Mbit/s.

It probably works.
