Usercode I/O

Functions

• uint8_t os_digin (uint16t i)
  • read the status of a digital input pin
  • Parameters
    • i, the name of the digital input, as defined in the Digital I/Os of the module.
  • returns the status of the digital input
• void os_digout (uint16_t i, uint8_t value)
  • set a digital output pin high or low
  • Parameters
    • i, the name of the digital output, as defined in the Digital I/Os of the module.
    • value, the value to be written to the digital output (0 or 1).
• uint16_t os_algin_mv (uint8_t i)
  • read the voltage (in milivolts) on an analog input pin
  • Parameters
    • i, the name of the analog pin, as defined in the Analog Inputs of the module.
  • returns the voltage in milivolts of the analog input pin

Example Code

• Read analog pin ANA1 and send it on the CAN bus on datapoint "DATA2"
• Switch the output OUT_HSD2 based on the datapoint "DATA3"

uint16_t variable1;
variable1 = os_algin_mv(ANA1);

can_db_set_value(DATA2, variable1); //Datapoint "DATA2" must be defined in User Defined CAN Messages

variable2 = (uint8_t)can_db_get_value(DATA3); //Datapoint "DATA3" must be defined in User Defined CAN Messages

os_digout(OUT_HSD3, variable2);

• Return the value of the analog input pin 0 (ANA0) and write it to a variable

variable1 = os_algin_mv(ANA0);

• Return the value of digital input pin 0 (D_IN0) and write it to a variable

variable1 = os_digin(D_IN0);

• Turn digital outputs on and off

// Turn on digital output 0 (OUT_HSD0)
os_digout(OUT_HSD0, 1);

// Turn off digital output 5 (OUT_HSD5)
os_digout(OUT_HSD5, 0);
