Function Documentation

LCD_I2C_Setup()

int LCD_I2C_Setup ( i2c_inst_t *  I2C, uint  SDA_Pin, uint  SCL_Pin, uint  I2C_Clock  )

noexcept

Helper function to set up the I2C bus on Pi Pico.

Sets up the I2C bus given instance on the given pins with a specified clock rate. Defines the pins for the pico tools. It can be called from C or C++.

Parameters

I2C	is the I2C bus instance to use. Either i2c0 or i2c1.
SDA_Pin	is the Pi Pico Pin for the I2C SDA (data) line.
SCL_Pin	is the Pi Pico Pin for the I2C SCL (clock) line.
I2C_Clock	is the I2C bus speed. Typically 100000 or 400000.

Returns

(int) The actual (theoretical) I2C speed from i2c_init
