M5Stack Tab5 Review – Part 2: Getting started with ESP32-P4 firmware development using the ESP-IDF Framework and Arduino IDE

In the first part of the review, we checked out the hardware of the M5Stack Tab5 ESP32-P4 IoT development kit and tried the demo firmware, whose user interface allows the user to quickly experiment with the camera, microphone, speaker, WiFi, power consumption, GPIOs, RS485, and more. Since there’s no user application for the Tab5 at this stage, I decided to look into software development resources for the ESP32-P4 devkit in the second part of the review. I’ll first follow the instructions to build the demo firmware from source using the ESP-IDF framework, then analyze key aspects of the source and make some small modifications. After that, I’ll have a look at ESP32-P4 Arduino support via M5Unified and M5GFX library. ESP-IDF 5.4.1 installation and ESP32-P4 Hello World program The first step is to get the ESP-IDF 5.4.1 and configure ESP32-P4 following the instructions on the Espressif website, before testing it with […]
