Flash CircuitPython 9 (Alpha 5) on ESP32-C6, and control on-board RGB LED (NeoPixel).

Image
Flash CircuitPython 9.0.0-alpha.5 on YD-ESP32-C6-N16 , and control on-board RGB LED (NeoPixel). Run on Windows 11. esptool is needed to flash firmware on ESP-C6, read  Install esptool on Windows 11 . Steps to flash CircuitPython firmware on ESP32-C6: Visit https://circuitpython.org/downloads , search boards of ESP32-C6. There are no 16MB Flash version, so I try "ESP32-C6-DevKitC-1-N8". Download .bin of CircuitPython 9.0.0-alpha.5 now. Connect to USB connector marked "COM". Erase Flash with command: esptool --chip esp32c6 --port <COM> erase_flash Write Binary Data to Flash with command: esptool --chip esp32c6 --port <COM> write_flash 0x0 <.bin> Reconect USB to connector marked "USB". Open Thonny Python IDE. In Thonny: > Run > Configure interpreter... Select interpreter of "CircuitPython (generic)" and Port, then OK.

Raspberry Pi Pico/TFT_eSPI display on 3.5" 480 x 320 ILI9488 SPI TFT

Image
This video show  Raspberry Pi Pico (RP2040) using TFT_eSPI library display on 3.5" 480 x 320 ILI9488 SPI TFT , in Arduino Framework. Install TFT_eSPI in Arduino IDE's Library Manager. It's strongly suggested to visit TFT_eSPI page , scroll down to Tips section. 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. To locate Arduino library folder: > File > Preferences... Copy the path inside Sketchbook location. Open file explorer to open Sketchbook location, to locate Arduino library folder. Create a new folder in your Arduino library folder called "TFT_eSPI_Setups". Copy the file /TFT_eSPI/User_Se...

Check if I belongs to dialout group (Linux command)

Image
Tested on Linux Mint 21.2, to check if I belongs to any group, Linux command id and groups can be used. id: Print user and group information for each specified USER, or (when USER omitted) for the current user. id id <user> groups: Print group memberships for each USERNAME or, if no USERNAME is specified, for the current process (which may differ if the groups database has changed). groups groups <user>

Install Espressif IDF Extension in VS Code to program ESP32-C3 Run on Linux Mint 21.2 (over Windows 11/VirtualBox)

Image
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. ...
