I‘ve had some trouble using I2C(1) bus on a nucleo-f303re board.
After reading the stm32f303re datasheet and changing some parameter values in boards/nucleo-f303re/include/periph_config.h ( before: .dev = I2C3, … .sda_pin = GPIO_PIN(PORT_A, 5), .scl_af = GPIO_AF5,
now: .dev = I2C3, … .sda_pin = GPIO_PIN(PORT_B, 5), .scl_af = GPIO_AF3, )
everything worked fine. Should those values also be changed in the RIOT repository? Did I understand something wrong?
