This example demonstrates the usage of the POK modules. The example shows how to listen for POK error events using the ESM, and also forcing an error in order to demonstrate application notification of overvoltage and undervoltage events.

The example demonstrates:

* Undervoltage event detection
* Overvoltage event detection

Use Cases

Use Case	Description
UC-0	An under-voltage POK instance is configured to a threshold value that will force the undervoltage

event.Error event is triggered and application is notified of the event. UC-1 | An over-voltage POK instance is configured to a threshold value that will force the overvoltage event. Error event is triggered and application is notified of the event.

Supported Combinations

Parameter	Value
CPU + OS	m4fss0-0 nortos
	r5ss0-0 nortos
Toolchain	ti-arm-clang
Board	am64x-evm
Example folder	examples/sdl/pok/

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
