Counter 1 & 2 are hardware integrated 16-bit counters, they are triggered by INP1 & INP2.
You can test the counter with push buttons Inp1 and Inp2 : the counter adds 1every time one of these two buttons
is pressed. The debouncing control allows you to determine the reaction time of the counter (0ms - 2ms - 10ms -
1000ms).
You can use the internal analogue voltage to simulate the analogue input via potentiometers ATT1 (RV1) & ATT2
(RV2).
The scroll bars AD1 & AD2 change on the screen whenever you adjust the position of the potentiometers. The
"digital" value (0 to 255) of this internal analogue voltage can be read directly under the scroll bars.
