1.19 PWM Generation

This example shows how to configure the PWM to generate synchronous 3-phase PWM signals with dead time (used for motor control). The duty cycle of the PWM is updated in the interrupt handler.

Path of the application within the repository is apps/pwm/pwm_synchronous_channels/firmware.

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 Program the application using their respective IDEs
2. Observe the high-side and low-side PWM waveforms on the oscilloscope
3. Observe the dead time between the high side and low side
