+ * \brief 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.

- *
- * 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.
