2. GPIO Example

1. Overview

The K230 chip integrates 64 GPIO pins, each of which can be configured as either input or output mode. It also supports pull-up and pull-down resistor configurations as well as drive strength settings. The flexible configuration of GPIO pins makes it widely applicable in various scenarios.

2. Example

The following code example demonstrates how to configure and control GPIO pins using the GPIO module:

from machine import Pin

# Instantiate Pin2 as output mode, configure it with no pull-up/pull-down (PULL_NONE), and set drive strength to 7
pin = Pin(2, Pin.OUT, pull=Pin.PULL_NONE, drive=7)

# Set Pin2 to output high level
pin.value(1)

# Set Pin2 to output low level
pin.value(0)

Note

For detailed interface and functionality descriptions of the Pin module, please refer to the API documentation.
