Tiny USB Knob - Instructions for flashing new firmware

You will need a PC running Windows 7 or later. It might work in a VM but I think probably not. The VM would need USB passthrough, available in VirtualBox, not sure about others.

1. Install WCHISPTool

Visit the link above and click the download button

2. Download firmware

For ORIGINAL VERSION (USB Micro-B female)

• To flash the device as a USB Volume knob, download tiny_usb_knob_2.0.bin
• To flash the device as a MIDI Control knob, download tiny_midi_knob_1.0.bin

For DIRECT (USB Type A male) VERSION 1 or 2

• To flash the device as a USB Volume knob, download hid_knob_DIRECT.bin

Note, there is no MIDI firmware available for DIRECT VERSION 1 or 2

3. Put the device in Firmware Flashing Mode

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 the file you downloaded in step 2 (either tiny_usb_knob_1.0.bin or tiny_midi_knob_1.0.bin).
• 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'.
