USB cable into the QSK board and the other into a
USB port on your PC.

message. After a few seconds, “RT1: xxxx,
AN0: xxxx” will be displayed on the LCD.
ii) The three User LEDs will blink sequentially
(back and forth).
iii) The LED flash rate is controlled by the Analog
Adjust (R11) potentiometer (which is connected
to the MCU analog-to-digital converter’s
(ADC) AN0 input).The 10-bit ADC value of
AN0 is also shown on the LCD as a decimal
number. The input, AN1 value Thermistor R20
is shown on the “RT1:” line of the LCD.

clockwise. This alters the flash
rate of the LEDs, and increases or
decreases the AN0 value shown
on the LCD.

change the LCD to read “Button
