ESP32C3 implements a NorFlash programmer and burner

## Demo video:
B station: (Under construction...)

## Introduction:
Use Hezhou 9.9's ESP32C3 to make a NorFlash programmer and burner. Supports NorFlash burning in SOP-8 package within 16M.

## Update log:
2023-05-17 Create this project

## Basic operations:
```bash
# Check the capacity of the flash
python esptool.py --port /dev/cu.usbmodem143301 flash_id


# Save flash firmware
python esptool.py --port /dev/cu.usbmodem143301 -b 460800 read_flash 0x0 0x400000 4m.orgin.bin


# Burn flash firmware
python esptool.py --port /dev/cu.usbmodem143301 -b 460800 write_flash 0x0 4m.new.bin

```

## Notes:
- This PCB is actually a splicing of three boards. The proofing fee of Jiali Chuang is relatively high. I spent 74, T_T. The sponsor is free to choose~
- The soldering of the SOP-8 adapter is more troublesome, and the FPC pins are particularly easy to be tinned. After soldering, use a multimeter to test whether it is normal.
- When placing the FLASH chip, pay attention to the position of pin 1, and don't put it upside down.
