Flashing MicroPython Firmware on the ESP32-C5_MINI using esptool

Image
This post walks you through the step-by-step process of flashing MicroPython firmware onto the ESP32-C5_MINI . 1. Download the MicroPython Firmware First, grab the correct binary for your chip: Visit the official MicroPython Download Page . Search or scroll down to the ESP32 section and locate the ESP32-C5 targets. Select ESP32-C5 by Espressif and download your preferred .bin file version. 2. Flash the Firmware (The 0x2000 Offset) To flash the firmware, connect your board to your computer and run the following esptool command. ⚠️ Crucial Note: Unlike older ESP32 chips (like the S3) which often start flashing at 0x0 , the ESP32-C5 requires you to write the flash starting exactly at address 0x2000 . Run this command in your terminal (replace PORTNAME and the .bin filename with your actual values): esptool --port PORTNAME ...

Dynamic WiFi Image Gallery run on Waveshare ESP32-S3-Touch-AMOLED-2.16/ESP32-S3-Touch-LCD-4B

Image
In my previous post, I demonstrated how to download and display JPG images via WiFi on the Waveshare ESP32-C5-WIFI6-KIT-N16R8 with an 240x320 ST7789 SPI TFT LCD using hardcoded filenames . This new implementation is much more flexible: filenames are now stored in a jpg_list.txt file on the server, allowing the ESP32 to download the images dynamically. I have also successfully tested this setup on the Waveshare ESP32-S3-Touch-AMOLED-2.16 with its 480x480 AMOLED (CO5300 driver) . (Scroll down for ESP32-S3-Touch-LCD-4B version). How it Works The program operates in three distinct phases: WiFi connection: The ESP32-S3 connects to a local WiFi access point and establishes communication with a Python-based HTTP server. Since the WiFi access point is a Windows 11 Mobile Hotspot and the Python-based HTTP server is running on that same PC, we can assume the server IP address is identical to the Access Point (Gateway) IP.
