Tiny USB Knob - Instructions for flashing new firmware
3. Put the device in Firmware Flashing Mode
- If you are converting an old Volume Knob (i.e. it has never been flashed with new firmware):
- Press and hold the button for more than 5 seconds
- If it's already a new knob (i.e. you bought it after March 25th 2024 or you've already flashed it with the firmware at least once):
- Activate Firmware Flashing Mode using the 'Advanced' button in the Web Config UI
- Or press the knob down while plugging in the device
- When the device goes into Firmware Flashing Mode you should see the LED flicker briefly.
4. Run WCHISPTool
- It should look something like this
- Click 'E8051 USB MCUs' to bring up the correct page
- Your device should show up in the 'Dev List'. If it doesn't try clicking 'Search'
- Click the browse button for 'Object File 1' and select
tiny_usb_knob_1.0.bin that you downloaded in step 3.
- Make sure 'Run The Target Program After Download' is checked
- Click 'Download' to flash the device
- Inspect the 'Download Record' for any errors
- Test the device - you will need to refresh the Web Config UI page or click 'Scan'.
