This video show steps to install Espressif IDF Extension in VS Code to program Espressif ESP32-C3-DevKitM-1 . Here VS Code run on Linux Mint 21.2 (over Windows 11/VirtualBox) . Basically, it follow the steps in  ESP-IDF Visual Studio Code Extension Installation Guide to - Install ESP-IDF Extension to VS Code. - Install Prerequisites for Linux . - Configure ESP-IDF extension. - Add 60-openocd.rules for permisssion delegation in USB to added in /etc/udev/rules.d/. Then follow Basic use of the extension to: - Create project of Blink example. - Grant permission to user to access USB port. - finally flash on ESP32-C3-DevKitM-1. Fix IntelliSense error of: identifier "CONFIG_BLINK_PERIOD" is undefined identifier "portTICK_PERIOD_MS" is undefined in VS Code/ESP-IDF Blink Example. With auto-generated code with default setting, it can be built, flash and run on ESP32-C3 device without error. Is it OK, ...NOT. ...

Previous posts introduced " MicroPython bluetooth remote control LED between Raspberry Pi Pico W and ESP32-C3, using aioble library " and " BLE examples run on Nano 33 BLE (as Peripheral) and Uno R4 WiFi (as Central) using ArduinoBLE in Arduino Framework ". This video further test how BLE communication between that two approach.

Last post introduced " MicroPython bluetooth example using aioble library, temp_client.py and temp_sensor.py ". This post modified it to remote control LED via bluetooth between Raspberry Pi Pico W and ESP32-C3-DevKitM-1 , achieve the same function as in " BLE examples run on Nano 33 BLE (as Peripheral) and Uno R4 WiFi (as Central), using ArduinoBLE in Arduino framework ". Basically, the bluetooth/aioble parts on both boards are same, but code in separated is caused by different configurare of onboard LED.

With recent update of MicroPython, bluetooth is supported in Raspberry Pi Pico W build. The official guide " Connecting to the Internet with Raspberry Pi Pico W book (2023-06-14) " updated with example using bluetooth. Read my previous post " Prepare MicroPython Bluetooth service example on Raspberry Pi Pico W ". Refer to MicroPython libraries document - bluetooth , higher-level aioble library is recommended. aioble provides an object-oriented, asyncio-based wrapper for MicroPython's bluetooth API. (* This module is still under development and its classes, functions, methods and constants are subject to change.) This video introduce the alternative using aioble library, run on Raspberry Pi Pico W and  Espressif ESP32-C3-DevKitM-1 , both run MicroPython v1.21.0. Notice that aioble is included in Raspberry Pi Pico W MicroPython v1.21.0, but not in v1.20.0. Fail in await connection.disconnected() using aioble library...

This video show how to drive 4 inch 480x320 SPI TFT ST7796 with XPT2046 Touch on ESP32-C3-DevKitM-1 (arduino-esp32) using TFT_eSPI. Include prepare user setup file and touch calibration. TFT_eSPI can be installed using Arduino IDE Library Manager. Check the GitHub page of TFT_eSPI , it's Arduino and PlatformIO IDE compatible TFT library optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32 that supports different driver chips. It's strongly recommended to follow the steps in Tips section in TFT_eSPI page: If you load a new copy of TFT_eSPI then it will overwrite your setups if they are kept within the TFT_eSPI folder. One way around this is to create a new folder in your Arduino library folder called "TFT_eSPI_Setups". You then place your custom setup.h files in there. After an upgrade simply edit the User_Setup_Select.h file to point to your custom setup file. Connection between ST7796 SPI ...
