Scripting functions for RaceCapture/Pro

getGpio( channel )

Retrieves the state of the specified GPIO channel

  • params
    • channel: integer 0 - 2
  • returns:
    • state: 1 = channel is high, 0 = channel is low

When the channel is configured for input mode, a voltage high input (> 2 volts) will read as 1; a voltage low will read as 0. A disconnected channel will read as high due to the internal pullup resistor.

When the channel is configured as output, the channel reads 1 when the channel is activated (output transistor is connected to ground) and 0 when the channel is deactivated (pullup resistor is active)

setGpio ( channel, state )

Sets the state of the GPIO channel when the channel is configured for output mode.

  • params
    • channel: integer 0 - 2, state - 1 = output active; 0 = output inactive
  • returns:
    • none

When the state specified is 1, the output is active (transistor is connected to ground). When state is 0, transistor is disconnected, and pullup resistor is active.

When configured for input mode this function has no effect.

getButton()

Gets the state of the front panel pushbutton.

  • params
    • none
  • returns
    • state: 1 = pushbutton is depressed; 0 = pushbutton is not depressed

isSDCardPresent

Indicates if an SD card is present in the socket

present isSDCardPresent()

  • params
    • none
  • returns
    • present: 1 = SD card is present in socket; 0 = SD card not present

isSDCardWritable()

Indicates if the SD card is writable (lock switch on SD card is active)

  • params
    • none
  • returns
    • writable: 1 = SD card is writable; 0 = SD card is not writable

setPwmDutyCycle( channel, dutyCyclePct )

Sets the duty cycle of the specified PWM / Analog output channel to the specified duty cycle percentage

  • params
    • channel: PWM / Analog output channel 0 - 3
  • returns
    • none


setPwmPeriod( channel, period )

Sets the period of the specified PWM / Analog output channel to the specified period

  • params
    • channel: PWM / Analog output channel 0 - 3
    • period: The period value
    • returns
  • none


setAnalogOut( channel, voltage )

Sets the output voltage of the specified PWM / Analog output channel to the specified period. A convenience function equivalent to setPwmDutyCycle that translates voltage to PWM percentage.

  • params
    • channel: PWM / Analog output channel 0 - 3
    • voltage: the specified output voltage ( 0 - 5v)
    • returns
  • none


getTimerRpm(channel)

Returns the current RPM of the specified timer input channel. Note, the timer channel configuration must be set to RPM mode.

  • params
    • channel: Timer channel 0 - 3
    • returns: RPM value


getTimerPeriodMs(channel)

Returns the current duration of the full cycle pulse of the specified timer input channel, in milliseconds. Note the timer channel configuration must be set to Duration mode.

  • params
    • channel: Timer channel 0 - 3
    • returns: millisecond value


getTimerFrequency(channel)

Returns the current frequency present on the specified timer input channel, in Hz. Note the timer channel configuration must be set to Frequency Mode.

  • params
    • channel: Timer channel 0 - 3
    • returns: Frequency in Hz


getTimerRaw(channel)

Returns the current raw timer value as measured on the specified timer input channel.

  • params
    • channel: Timer channel 0 - 3
    • returns: Raw timer value between 0 - 65535


getAnalog(channel)

Reads the scaled analog value for the specified analog input channel.

  • params
    • channel: Analog input channel 0 - 7
    • returns: Scaled / calculated value for the specified analog channel as defined in the channel scaling configuration

getAnalogRaw(channel)

Reads the raw analog value for the specified analog input channel.

  • params
    • channel: Analog input channel 0 - 7
    • returns: The raw value measured by the 10 bit Analog to Digital Converted on the specified analog channel, between 0 - 1023

readSerial(port)

Read a line of data from the specified serial port. This command blocks until a newline ('\n') character is received on the port.

  • params
    • port: Serial port 0 - 1
    • returns: a line of serial data
