I recently upgraded my setup from esp-idf 5.1.2 to 5.2, and am trying to write a driver for a magnetic encoder that configures the chip via i2c. This code/driver runs fine on an esp32-c3 seeed module I have, but crashes the same way on two different esp32-s3 boards I've tried. I don't understand the error that's being offered. I am using:
Code: Select all
#include "driver/i2c_master.h"
Code: Select all
// Per these docs:
// https://docs.espressif.com/projects/esp-idf/en/v5.2/esp32/api-reference/peripherals/i2c.html#i2c_master_controller
// We are configuring the i2c master bus first.
i2c_master_bus_config_t i2c_master_config = {
.clk_source = I2C_CLK_SRC_DEFAULT,
.i2c_port = I2C_MASTER_PORT,
.scl_io_num = I2C_MASTER_SCL_IO, // SCL pin
.sda_io_num = I2C_MASTER_SDA_IO, // SCL pin
.glitch_ignore_cnt = 7, // a default from esp's docs
.flags.enable_internal_pullup = true,
};
i2c_master_bus_handle_t bus_handle;
i2c_new_master_bus(&i2c_master_config, &bus_handle);
