Flash CircuitPython on ESP32-S3-DevKitC-1 using esptool, run on Ubuntu MATE 22.04 LTS.

Flash CircuitPython 7.3.2 on ESP32-S3-DevKitC-1 using esptool, run on Ubuntu MATE 22.04 LTS.



- Install esptool
   (esptool is a serial utility to communicate & flash code to Espressif chips)

- Download firmware
Visit CircuitPython download page.
Search "S3" and download firmware for "ESP32-S3-DevKitC-1-N8R8 by Espressif".
Download firmware in .bin.

- Flash firmware using esptool

Connect USB to the port marked "UART".

Erase flash:

esptool.py --port /dev/ttyUSB0 erase_flash

Flash firmware:

esptool.py --chip esp32s3 --port <port> write_flash -z 0x0 <firmware.bin>

To run it in CircuitPython REPL, connect to the port marked "USB".

remark:
If you cannot connect/detect ttyUSB0, check previous post cp210x converter now disconnected from ttyUSB0 by 'brltty', on Ubuntu MATE 22.04 LTS.

Next:
- Download and install CircuitPython Library to CIRCUITPY drive's lib folder

Exercise of CircuitPython on ESP32-S3-DevKitC-1:
~ ESP32-S3-DevKitC-1/CircuitPython to drive NeoPixel, onboard and offboard
~ ESP32-S3/CircuitPython to drive SSD1331 SPI color OLED
~ 320x240 ILI9341 SPI TFT drived with ESP32-S3/CircuitPython
~ ESP32-S3/CircuitPython, generate QR Code, display on ILI9341 SPI TFT.
~ ESP32-S3/CircuitPython 8 display on ST7789 SPI TFT
~ Play animated GIF in CircuitPython 8.1.0 Beta 0, run on ESP32-S3, display on ST7789 SPI TFT.
~ ESP32-S3/CircuitPython act as socket client, connect to HC-25 WiFi Module.

FNIRSI 2C23T 3-in-1 Dual Channel Oscilloscope/Multimeter/Signal Generator Steps to upgrade of FNIRSI 2C23T 3-in-1 : Remark@2024-03-23: Please check the comment by dmitriivanov5330 in the video. How to distinguish the hardware? please press menu , and if you can see the words in Setting: "Hardware version No.:XXXXX " then the device is made with latest hardware, it has the latest firmware, and now it doesn't need to upgrade.  If you can not see the words in Setting: "Hardware version No.:XXXXX ", then it is made with old hardware, and it can be upgraded with firmware 2.0.2, and if you confirm this, the firmware for the device with old hardware is attached.  By the way, the firmware 2.0.2 only fixes device with old hardware. The device with new hardware can not use this firmware to upgrade. - Download firmware from FNIRSI Official Web Site - Connect USB to PC - While 2C23T is OFF, press and hold MENU button, then press POWER button to power...
