Detailed Description

Test for PWM driver (implementation).

This is a simple test for PWM driver. This module is target independent, so you can test all target that BeRTOS support. To use this test you should include a pwm_map.h header where are defined the PWM channels for your target. Then you should add or remove a test setting in pwm_test_cfg array, and edit a value for your specific test. Afther this, all is ready and you can test PWM driver.

The test check first if all PWM channel starts, and then try to change a PWM duty cicle for all channel. The change of duty cycle is operate when a PWM channel is enable, in this way you can see if a pwm signal is clean and work properly. The duty value is change incrementaly, and when it arrive to 100% or 0%, we reset the duty value and restart the test. Further the duty test, we check also a PWM polarity, infact when we reach a reset duty value, we invert a polary of PWM wavform. So you can see if the hardware manage correctly this situation.

Note: To be simple and target independently we not use a timer module, and so the delay is do with a for cycle.
