[−][src]Macro hifive1::pins

macro_rules! pins {
    ( $gpio:ident, ($($name:ident),+) ) => { ... };
}

Returns tuple of pins for given gpio object mapped accordingly

Mappings

  • none — Returns () for empty pin if needed in tuple
  • spi0_<x> — SPI pins where <x> is one of (sck, mosi, miso, ss0, ss2, ss3)
  • i2c0_<x> — I2C pins where <x> is one of (sda, scl)
  • uart0_<x> — UART pins where <x> is one of (tx, rx)
  • dig# — Digital/physical pins on the board where # is from range 0..19
  • led_<x> - Internal LED light pins <x> is one of (red, green, blue)

Example

let (mosi, miso, sck, cs) = pins!(gpio, (spi0_mosi, spi0_miso, spi0_sck, spi0_ss0));
// (gpio.pin3, gpio.pin4, gpio.pin5, gpio.pin2)
