Gpio Driver Application - Freescale Semiconductor DSP56800E User Manual

5.8.4

GPIO Driver Application

The GPIO driver application is designed for Motorola/Freescale EVM's and it is intended to
illustrate the usage of this driver by a real example. It also verifies the functionality by blinking
user LEDs on the EVM.
The GPIO driver
Source}\..\sample_applications\MC56F8346EVM\gpio_demo and consists of the application
gpio_demo.mcp and the source code for the application main.c.
See Table 5-269 for the LED configuration, specific to the individual EVM's.
