Scripting functions for RaceCapture/Pro

getGpio

Retrieves the state of the GPIO ports

state getGpio(port)

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

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

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

setGpio

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

setGpio(port, state)

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

When the state specified is 1, the output is active (transistor is conneced 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.

state getButton()

• params: none
• returns: 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: 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)

writable isSDCardWritable()

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