nRF5340 I2C pins

[GunnerDx]

Greetings,

I'm trying to develop a project on the nRF5340 DK where I collect measurement data from an I2C sensor (LPS27HHW) before sending the data via bluetooth. My firts problem is that I don't know here the I2C pins are on the board (SDA and SCL). I also heard that it is possible to choose any pin on the board for different drivers, if so, how can that be done in code (setting a specific pin) ?

Thank you in advance.

When you init the twi driver you need to pass a nrfx_twim_config_t struct with the pins you want to use for the I2C.

    const nrfx_twim_config_t config = {
        .scl                = scl_pin,
        .sda                = sda_pin,
        .frequency          = freq,
        .interrupt_priority = APP_IRQ_PRIORITY_HIGH
    };

    err_code = nrfx_twim_init(&m_twi, &config, twi_handler, NULL);

check the examples at 'examples/peripheral/twi_sensor/main.c'
