configurePin

Configure and display pin modes on BBC micro:bit board

Description

example

pinMode = configurePin(microbitObj,pin) displays the mode of the pin on the BBC micro:bit board, specified as a microbit object .

example

configurePin(microbitObj,pin,mode) sets the mode on the specified pin on the BBC micro:bit board, specified as a microbit object.

Examples

collapse all

microbitObj = microbit('COM3');
configurePin(microbitObj,'P0')
ans =

Unset
microbitObj = microbit('COM3');
configurePin(microbitObj,'P0','PWM');

Display current pin mode.

pinMode = configurePin(microbitObj,'P0')
pinMode =

PWM

Display current pin mode.

microbitObj = microbit('COM3');
pinModeP0 = configurePin(microbitObj,'P0')
pinModeP0 =

AnalogInput

Change the pin mode to 'Unset' and display the current mode.

configurePin(microbitObj,'P0','Unset');
pinModeP0 = configurePin(microbitObj,'P0')
pinModeP0 =

Unset

Input Arguments

collapse all

BBC micro:bit hardware connection, specified as a microbit object created with the microbit function.

Pin number on the BBC micro:bit board, specified as a character vector.

Example: 'P0'

Pin mode specified as a character vector. Valid pin modes are:

  • 'AnalogInput' — Acquire analog signals from the pin. The pins that support analog input signals are P0, P1, P2, P3, P4 and P10.

  • 'DigitalInput' — Acquire digital signals from the pin.

  • 'DigitalOutput' — Generate digital signals from the pin.

  • 'I2C' — Specify that the pin be used as an I2C (Inter-Integrated Circuit) interface. The pins that support I2C are P19 and P20.

  • 'PWM' — Specify that the pin uses PWM (Pulse Width Modulation).

  • 'SPI' — Specify that the pin be used as an SPI (Serial Peripheral Interface). The pins that support SPI are P13, P14, and P15.

  • 'Unset' — Clear the mode of the pin. The pin is no longer reserved and can be automatically set at the next operation.

Output Arguments
