Flash with Web Tools

This chapter covers how to flash your device with a pre-built binary.

1. Connect the device with a USB-C cable.

2. Download a .bin from the latest GitHub release:

   • If this is the first time you are flashing Crimpdeq firmware to your device, download crimpdeq-merged.bin.
   • If you are updating firmware on a device that is already flashed, download crimpdeq.bin.

3. Choose a web flasher. Use either:

   • esp.huhn.me
     • See this blog post for extra details.
   • Adafruit ESPTool

4. Click Connect and select the serial port for your ESP board.

   • In Adafruit ESPTool, the port often appears as USB/JTAG serial debug unit....

5. Click Erase only if this is the first time you are flashing this device.

   ⚠️ Note: Erasing the device also erases stored calibration values. Skip this if the device was already programmed and calibrated.

6. Upload your .bin:

   • If you are using crimpdeq-merged.bin -> address 0x0
   • If you are using crimpdeq.bin -> address 0x10000

7. Click Program.
