Processor Interaction
Processor Interaction with the Keyboard and Displays
The keyboard is controlled by a microcontroller which scans the cap sense for key presses, keeps the display updated, and
reads any position from the XY pad. Periodically (several times per second) the main processor polls the keyboard processor,
receiving status of any keys pressed or XY position touch and updates the display as required.
Processor Interaction with Oscillators
The main processor controls the internal oscillators that generate the therapy wave forms. It initially calibrates the proper
output frequencies during the test cycle, and then keeps track of the frequency the rest of the time the unit is on. If the
oscillator happens to drift too far out of range for the processor to calibrate it, the processor will give an error message.
During the treatment, the processor causes the sweep frequency oscillator to change its frequency at a controlled rate. It
chooses the rate and frequency from what is selected on the keyboard when the treatment is set up, or when changes are
made during the treatment. It tracks and keeps the fixed frequency where it should be during the treatment. It also keeps
track of the 2500 Hz signal that creates the Russian therapy (turns it on and off at a 50 Hz rate).
Oscillators
1. 4 KHz fixed
2. 4000-4010 Hz (Interferential Low option)
3. 4080-4150 (Interferential High option)
4. 2500 Hz (Russian)
5. 4000-10,000 (Fixed Frequency)
