+This crate contains a subset of the [**Linux Simple I/O
+Library**](https://github.com/pmunts/libsimpleio) Ada packages that are
+relevant for building programs for the MCP2221 USB Raw HID I/O expander.
+
+This crate can be built for Linux, MacOS, or Windows targets.
+
+The [MCP2221A](https://www.microchip.com/en-us/product/MCP2221A) is a
+[PIC16F1455](https://www.microchip.com/en-us/product/PIC16F1455)
+microcontroller that has been preprogrammed with firmware to implement
+*two* USB devices: a USB serial port and a raw HID device that acts as
+an I/O expander providing one [I2C](https://i2c.info/) bus controller
+(master only) and four
+[GPIO](https://en.wikipedia.org/wiki/General-purpose_input/output) pins
+(**`GP0`**, **`GP1`**, **`GP2`**, and **`GP3`**).
+
+The GPIO pins **`GP1`**, **`GP2`**, and **`GP3`** can be configured for
+some alternate functions, including 10-bit A/D inputs or 5-bit D/A
+outputs:
+
+**`GP1`** : **`GPIO ADC1`**  
+**`GP2`** : **`GPIO ADC2 DAC1`**  
+**`GP3`** : **`GPIO ADC3 DAC2`**
+
+The MCP2221A replaces an earlier part, the MCP2221. The only difference
+between the older MCP2221 and the newer MCP2221A is that the latter
+supports some higher baud rates on the USB serial port device. Since
+this crate only deals with the raw HID I/O expander functions, it will
+work fine with either the older MCP2221 or the newer MCP2221A.
