Member Data Documentation

uint struct_ConfigSlaveI2C::baud_rate = 100 * 1000

the I2C baudrate:

i2c_slave_handler_t struct_ConfigSlaveI2C::i2c_slave_handler

a function pointer to the IRQ i2c_slave_handler, required by pico SDK, to the program that manage the reception of i2c message by the slave interface

NOTICE: This i2c_slave_handler is the one given to NVIC IRQ map. It seems that it must be a static function defined in the main code.
