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-on in firmware upgrade mode. 2C23T will appear as USB driver.
- Copy the firmware to USB driver of 2C23T.
- 2C23T will restart after upgraded.


2C23T Signal Generator function test

Just try the signal Generator function of FNIRSI 2C23T, monitored with 2C23T itself and Scoppy Oscilloscope App (+ Raspberry Pi Pico)

boochow/MicroPython-ST7735 is a modified version of GuyCarver's ST7735.py ST7735 TFT LCD driver , for micropython-esp32. This video show steps to prepare boochow/MicroPython-ST7735 driver and font files. Tested on  Espressif ESP32-C3-DevKitM-1 running MicroPython v1.19.1, to display on  1.8 inch 128x160 ST7735 SPI TFT .
