The GPIO sample set contains the following samples: -Minifilter | Sample Description ------------|------------------- -SimGpio | The files in this sample contain the source code for a GPIO controller driver that communicates with GpioClx through the GpioClx device driver interface (DDI). The GPIO controller driver is written for a hypothetical memory-mapped GPIO controller (simgpio). The code is meant to be purely instructional. An ASL file illustrates how to specify a GPIO interrupt and I/O descriptor in the ACPI firmware. -SimGpio_I2C | The files in this sample contain the source code for a GPIO controller driver that communicates with GpioClx through the GpioClx DDI. In contrast to the SimGpio sample, the GPIO controller in this sample is not memory-mapped. The GPIO controller driver is written for a hypothetical GPIO controller that resides on an I2C bus (simgpio_i2c). The code is meant to be purely instructional. An ASL file illustrates how to specify a GPIO interrupt and I/O descriptor in the ACPI firmware. -SimDevice\kmdf | The purpose of this sample is to show how a driver opens a device and performs I/O operations on a GPIO controller in kernel mode. Additionally, this sample demonstrates how the driver connects to a GPIO interrupt resource. The ASL file illustrates how to specify a GPIO interrupt and I/O descriptor in the ACPI firmware. -SimDevice\umdf | The purpose of this sample is to show how a driver opens a device and performs I/O operations on a GPIO controller in user mode.
