// Function to change the output state of the gpio pin // // Calling Sequence // u8RPI_DigitalOuts(pin,state) // // Parameters // pin : pin of RPi to be used // state : desired output state for pin (0 -> LOW, 1 -> HIGH) // // Description // There are few pins available on RPi as Gpio or digital i/o. These pins can be used as digital output or input. 'Pin' name must be provided from list provided. Please refer '' for complete list of pins. 'state' can be 0 or 1 depending upon desired output (Low/High). RPI_DigitalSetup with appropriate arguments must be called before using this function. // Examples // u8RPI_DigitalOuts(RPI_GPIO_P1_03,1) //Sets pin 3 of header P1 as 'high' output // // // Authors // Siddhesh Wani // #include "types.h" #include "RPIPeripheralDigital.h" uint8 u8RPIDigitalOuts(uint8 pin, uint8 state) { if (state == 0) //low output bcm2835_gpio_clr(pin); if (state == 1) //high output bcm2835_gpio_set(pin); }
