# ‌Prerequisites

You'll need following items in order to burn the firmware into the device

1. A verified USB-TTL dongle (in rare cases the dongle won't work so you'll probably need another one).
2. A 2.54mm spacing 6-pin clamp burner.
3. A target device with an OLED screen attached to it.

# To use this toolset

1. Connect the burner and the dongle.
2. Connect the dongle to your computer.
3. Run the 'Device Manager' on your computer to get the corresponding COM port of the dongle.
4. Start a CMD shell in this directory.
5. Type `burn.bat COMPORT` and hit Enter where the COMPORT is the one you've got in step 3.
6. Wait until the command finishes, check the device see if it's working properly.
7. If the device does NOT work as intended, do step 5 again.
8. If the device does NOT work, try `burn_low_baud.bat COMPORT` with the same parameter.
