Introduction

This example uses the ECAP in APWM mode to generate a PWM signal.

The example does the below

• Configures ECAP in APWM mode and configures values in period and compare registers using sysconfig.
• Waits for the specified time using the ECAP ISR.

External Connections

Connect OUTPUTXBAR1 output to oscilloscope

AM263X-CC

When using AM263x-CC with TMDSHSECDOCK (HSEC180 controlCARD Baseboard Docking Station)

• Connect HSEC Pin 81 to oscilloscope

AM263X-LP

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Boards	am263x-cc, am263x-lp
Example folder	examples/drivers/ecap/ecap_apwm_mode/

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)
• Establish connections as mentioned in External Connections section
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
