This is a basic application which demonstrates the use of PWM. This application can operate in one of two mode: DEMO_MODE and TESTING_MODE.
The DEMO_MODE is intended to be used for demonstrating how the PWM affects the dimming of a real LED.
When the application is in DEMO_MODE, the PWM will be generated on a single pre-determined pin, and the duty cycle will go through a set of predefined values.
The TESTING_MODE is intended to be used to test the PWM on all supported pins, using a logic analyzer.
When the application is in TESTING_MODE, the PWM will be generated on every supported pin, going through a list of predefined duty cycle values for each pin.
By default, the application runs in DEMO_MODE. Change the operation mode of the application via the preprocessor define in the pwm_led_dimming.c file.
#define TESTING_MODE 0 // Keep at 0 for DEMO MODE, set to 1 for TESTING MODE
