1.5 Clock Configuration

Clock system generates and distributes the clock for the processor and peripherals. This example application shows how to use the clock manager to configure the device to run at the max possible speed. A prescaled clock signal is routed to GPIO pin to measure the frequency and accuracy of the internal device clock.

Path of the application within the repository is apps/clock/clock_config.

To build the application, refer to the following table and open the project using its IDE.

To load the application binary onto the target device, we need to use at91bootstrap loader. Refer to the at91bootstrap loader documentation for details on how to configure, build and run bootstrap loader project and use it to bootstrap the application binaries.

The following table shows the target hardware for the application projects.

1. Build and run the application using its IDE
2. Observe the clock of ~2 MHz on clock output pin
3. LED should be blinking continuously
