Once the evaluation board is connected to the PC, device can be controlled via the software interface. The LM10502 should become active as soon as the USB cable is plugged in. When device starts up correctly, a yellow LED LD1 and green LED LD3 is illuminated. All the device functions can be accessed via the control buttons. - Page 3 Register information is given in the format: ‘’R/WXX:YY’’, where first letter indicates operation (read or write), XX is register address and YY is data.
