5.1. Blinky Application-Specific Files

5.1.1. main.c

The main.c file calls functions from the gModes.c and the port HAL as shown in Figure 5. This file also includes all

the main application code that sits in a while(1) loop, toggling the LED pins or reading the switches and printing

their status to the Console view.

5.1.2. myCpu.c

This file has the application-specific implementation of mySystemInit() called by system_sim3u1xx.c in the HAL.

For Blinky, this function:

Disables the Watchdog Timer.

Enables APB to the Port Bank modules.

Sets the Serial Wire Viewer pin (PB1.3) to push-pull.

Figure 6 shows the dependencies for myCpu.c.
