Hi Anton,
The new firmware version 0.3.0.0 and above does not perform a self-calibration. The behavior of the LED is now indicative of whether the PC Host can properly detect and enumerate the device. Windows should install the right drivers if you install the new drivers through the GUI installer and restart your system *without* the device plugged in. If this does not work, however, there is a way to do this manually by accessing the device manager, selecting LDC1000EVM, and installing the driver in the application installation folder /driver (e.g. "C:\Program Files\Texas Instruments LDC1000 EVM GUI\driver" ). The driver filename should be "evm.inf".
1. To do this on Windows 7, select "Devices and Printers".
2. right click "LDC1000EVM (COM#)" > Properties > Hardware Tab > Properties > Change settings
3. Driver Tab > Update Driver... > Browse my computer for driver software
4. Enter the location of the application installation subfolder "driver"
5. Continue on with the dialog and finish
6. Your device should show up as "EVM" instead of "LDC1000EVM"
Thanks,
