Compatibility Lincoln 60, Lincoln 60E
This example demonstrates how to use timers to generate PWM signals with different duty cycles. Run the example and observe the 4 signals using an oscilloscope.
Below is a list of the signals and what duty cycle they should be at:
- - P1.28 on J2 pin 19: duty cycle = 12.5%
- - P1.22 on J2 pin 13: duty cycle = 25%
- - P0.6 on J2 pin 5: duty cycle = 37.5%
- - P0.10 on J2 pin 9: duty cycle = 50%
The first UART, which is connected to the COM1 on the Lincoln microcontroller board, is configured for 115,200 bits per second, and 8-n-1 mode. When the program is started a message will be printed to the terminal. The below screen shot is of the timer_pwmsignal in action.
Below is a screen capture of the signals on P1.28 (J2 pin 19) and P1.22 (J2 pin 13).
Below is a screen capture of the signals on P0.6 (J2 pin 5) and P0.10 (J2 pin 9).
