Peripheral Drivers

Every application for a microcontroller needs drivers for its internal peripherals. The Embedded SDK includes integrated peripheral drivers that utilize features of the real-time kernel to optimize performance.

Source Code

The Embedded SDK source code archive contains a directory for each supported microcontroller (MCU). The MCU directory contains a collection of drivers for the on-chip peripherals. Each driver begins with an "mcu_" and contains a single source (.c) and header file (.h).

For example, the analog-to-digital converter (ADC) driver is comprised of files "mcu_adc.c" and "mcu_adc.h". To use the driver, add mcu_adc.c to your project and include mcu_adc.h to get access to the driver's API.

Minimum Drivers

Several of the MCU peripheral drivers are required for building any type of application. They provide basic support for the MCU. The required drivers are as follows:

• mcu_kernel.c/.h - Performs MCU specific tasks for the kernel.
• mcu_irq.c/.h - Provides support for the MCU specific interrupts.
• mcu_pin.c/.h - Provides support for reading and writing of the MCU pins.
• mcu_start.c/.s - Provides start-up code for the MCU. Provided for each toolchain.

All other drivers are optional and can either be included or excluded from compilation depending upon the requirements of application.
