USB-µPIO / PWMIO18
The /PWMIO18 firmware works as PC interface with 18 digital I/O lines with adjustable data direction. All I/O lines can generate a 8 bit / 50 Hz PWM signal, as well as blink and pulse signals.
Port D can be used to control servo drives. It generates a 50 Hz-PWM-signal with a pulse duration of1..2 ms for that purpose.Servo and PWM outputs are controlled by software, by ADC inputs or by an internal ramp generator.Ramps and pulses can be triggered with Port B signals.I/O lines are grouped to six ports (Port B, Port C, Port D).
Each I/O line can be configured foralternative purposes:
- Port B0…Port B5: Digital I/O, PWM, Blink/Pulse output, 6x Trigger input
- Port C0…Port C5: Digital I/O, PWM, Blink/Pulse output, 6x ADC
- Port D2…Port D7: Digital I/O, PWM, Blink/Pulse output, 6x Servo
In addition Port C voltages can be read with a 10 bit ADC
