Unable to get valid IO Expander handle for ESP32-S3 and LCD using TCA9554 IO Expander
Posted: Tue Oct 08, 2024 9:20 pm
Setup: Driving LCD (without touchscreen) with an Adafruit Qualia ESP32-S3 board which uses a TCA9554 I/O expander. LCD screen uses ST7701 panel driver. Attached schematics show connection between ESP32-S3, I/O expander and LCD screen.
Trying to run the rgb_avoid_tearing example from ESP-IOT-SOLUTION with this setup. For some reason, I'm unable to get a valid io_handle for the I/O expander.
Code as follows:
This is what my output looks like after successfully flashing the code to ESP32-S3. It goes into panic abort mode.
Functions in the esp_io_expander managed component seem to not register a valid I/O expander handle. The error is being thrown by the function i2c_master_cmd_begin(i2c_port_t i2c_num, i2c_cmd_handle_t cmd_handle, TickType_t ticks_to_wait) in component driver/i2c.c. The following line of code: throws the i2c driver not installed error. Array p_i2c_obj has a length of 8.
I'm lost on how to address the issue and would appreciate some help.
