What functions are available on the HAT40 connector, and how do I use them?
The 40-pin GPIO connector on UP Boards provides access to various interfaces like GPIO, UART, I2C, and SPI, which you can utilize depending on your operating system. The setup process differs slightly between Linux and Windows:
Linux: To use the 40-pin GPIO on Linux, you need to install the UP DKMS driver. This driver, available on GitHub, supports various UP Board models and enables you to configure and control the pins for different functions: https://github.com/up-division/pinctrl-upboard
Windows: On Windows, the UP SDK provides the necessary tools to access and control the 40-pin GPIO. The SDK includes drivers, documentation, and example code to help you get started with GPIO programming: https://downloads.up-community.org/download/up-sdk-for-windows-10-and-windows-iot/
