I2C using wb32laf (esp32s3)

[wpwaldner]

I have a wb32laf and am trying to get the I2C bus working to communicate to OLED display. The diagram indicate that the i2c pins are 17/18 but when I try and init the display, it get a BusWriteError

I have tried to follow the example at: https://github.com/ropg/heltec_esp32_lora_v3

Here is my code

#![no_std]
#![no_main]

use esp_backtrace as _;
use esp_println as _;
// use esp_hal::delay::Delay;
// use esp_hal::prelude::*;
use log::info;
use esp_hal::{
    i2c::master::{Config, I2c},
    delay::Delay,
    gpio::{Io, Input, Level, Output, Pull},
    prelude::*,

};

use core::fmt::Write;
use ssd1306::{mode::TerminalMode, mode::TerminalModeError::InterfaceError, prelude::*, I2CDisplayInterface, Ssd1306};

// use embedded_hal::i2c::{I2c, Error};
 use fugit::RateExtU32;
#[entry]
fn main() -> ! {
    let peripherals = esp_hal::init({
        let mut config = esp_hal::Config::default();
         config.cpu_clock = CpuClock::max();
        config
    });

    esp_println::logger::init_logger_from_env();

    let delay = Delay::new();
    // Reset the display and turn it onj
    let mut oled_reset = Output::new(peripherals.GPIO21, Level::Low);
    oled_reset.set_high();
    delay.delay(1.millis());
    oled_reset.set_low();
    delay.delay(20.millis());
    oled_reset.set_high();

    info!("Display Reset");

    let mut sda = Output::new(peripherals.GPIO17, Level::Low);
    let mut scl = Output::new(peripherals.GPIO18, Level::High);
  
    let config = Config {frequency: 100.kHz(),  timeout: Some(10)};

    let mut i2c = I2c::new(
        peripherals.I2C0,
        config
    )
        .with_sda(sda)
        .with_scl(scl);

    let interface = I2CDisplayInterface::new(i2c);

    let mut display = Ssd1306::new(
        interface,
        DisplaySize128x64,
        DisplayRotation::Rotate0,
    ).into_terminal_mode();

    if let Err(err) = display.init() {
        match err {
           InterfaceError(e)  => panic!("Interface error: {e:?}"),
            _ => panic!("Unknown error: {err:?}")
            }
    }
    display.clear().unwrap();
