How to Fix: Adafruit MCP2111 board gpioget: error reading GPIO values: No such file or directory

The issue is caused by the gpiochip0 being part of the laptop's built-in GPIO system, which is not compatible with the MCP2111 board. The solution is to use a different method to access the GPIO values, such as using the /sys/class/gpio directory.

Quick Answer: Try accessing the GPIO values through the /sys/class/gpio directory instead of gpioget.

The Adafruit MCP2111 board is not functioning correctly, resulting in an error message 'gpioget: error reading GPIO values: No such file or directory'. This issue affects users who have installed and are using the MCP2111 board with their system.

This problem can be frustrating for developers as it prevents them from utilizing the GPIO pins on the board. However, by following the steps outlined in this guide, you should be able to resolve the issue and start using your GPIO pins.

🛑 Root Causes of the Error

  • The primary reason for this error is that the gpiochip1 device node does not have a corresponding /sys/class/gpio directory. This is because the gpiochip1 driver requires a specific configuration in order to work properly.
  • An alternative cause could be that the gpiochip1 device node is not being recognized by the system due to a mismatch between the device ID and the expected GPIO values.

✅ Best Solutions to Fix It

Enabling GPIO on gpiochip1

  1. Step 1: To enable GPIO on gpiochip1, you need to create the /sys/class/gpio directory. You can do this by running the following command: sudo mkdir -p /sys/class/gpio)
  2. Step 2: Next, you need to specify the GPIO values for gpiochip1. You can do this by running the following commands: echo 0 > /sys/class/gpio/export && echo 1 > /sys/class/gpio/export && echo 2 > /sys/class/gpio/export && echo 3 > /sys/class/gpio/export)
  3. Step 3: Finally, you need to set the GPIO direction and value. You can do this by running the following command: echo 'in' > /sys/class/gpio/gpio1/direction && echo 0 > /sys/class/gpio/gpio1/value'

Using gpiochip0

  1. Step 1: As a workaround, you can use gpiochip0 instead of gpiochip1. However, this may not be ideal as gpiochip0 is part of the system's built-in GPIO controller and may have different behavior than gpiochip1.
  2. Step 2: To use gpiochip0, simply run the following command: gpioget 0 0

✨ Wrapping Up

By enabling GPIO on gpiochip1 or using gpiochip0, you should be able to resolve the 'gpioget: error reading GPIO values: No such file or directory' issue and start utilizing your GPIO pins.
