Did you accidentally tab or mouse-click away?
Especially for new users, a sudden inability to type may have been simply a bumping of the tab or mouse-click keys, putting the cursor’s focus in another place. Try clicking back to where you want to type.
Unplug/re-plug the USB cable
If your CharaChorder seems to be acting strangely, unplugging it by the USB cable and re-plugging it back in will force it to reconnect and reboot.
Re-install the firmware
If you have accidentally installed CharaChorder Lite firmware on your CharaChorder One please follow these steps:
Disconnect and reconnect your device
Change the Baud setting to 1200
Connect your device (with the connect button)
Refresh the page
Your device should now be in bootloader mode—load the correct firmware now.
