I/O, PWM, AD/DA

Most of the I/O pins of the Avisaro Module can be used as a "General Purpose Input or Output" (GPIO), as analogue input ports and as "Pulse Wide Modulation" ports. See pin layout for possible pin assignments.

• I/O Pins (Input, Output Pins or GPIO): Switch LEDs, get key inputs  
• PWM Pins (Pulse Width Modulation): Control servo-actuator, dim LEDs, digital to analog (with capacitor)  
• Analog Input: Temperatur sensors, any analog signal

Default settings

All pins are input ports by default (after power up). Than, the last port direction command is the one which counts. Example: CAN port two was activated and later pin 3 is declared as an output port - this ends up in port 3 being an output port and the CAN bus is not functional.

Electrical considerations

See the electrical section ( here) in the Module Manual for details on max current, etc .. for the port pins.

Command Interface

The I/O ports can be set and read by using the "port" command. See the I/O section ( here) in the Command Interface Manual for more details.

Basic Scripting

The I/O ports can be set and read by using the "put" and "get" command. See the I/O section ( here) in the Basic Scripting Manual for more details.
