pyb.ExtInt

Classes

ExtInt

Create an ExtInt object:

Module Contents

class pyb.ExtInt.ExtInt(pin, mode, pull, callback)

Create an ExtInt object:

  • pin is the pin on which to enable the interrupt (can be a pin object or any valid pin name).

  • mode can be one of: - ExtInt.IRQ_RISING - trigger on a rising edge; - ExtInt.IRQ_FALLING - trigger on a falling edge; - ExtInt.IRQ_RISING_FALLING - trigger on a rising or falling edge.

  • pull can be one of: - pyb.Pin.PULL_NONE - no pull up or down resistors; - pyb.Pin.PULL_UP - enable the pull-up resistor; - pyb.Pin.PULL_DOWN - enable the pull-down resistor.

  • callback is the function to call when the interrupt triggers. The callback function must accept exactly 1 argument, which is the line that triggered the interrupt.

disable() → None

Disable the interrupt associated with the ExtInt object. This could be useful for debouncing.

enable() → None

Enable a disabled interrupt.

line() → int

Return the line number that the pin is mapped to.

classmethod regs() → Incomplete

Dump the values of the EXTI registers.

swint() → Incomplete

Trigger the callback from software.

IRQ_FALLING: Incomplete

interrupt on a falling edge

IRQ_RISING: Incomplete

interrupt on a rising edge

IRQ_RISING_FALLING: Incomplete

interrupt on a rising or falling edge
