Lincoln Timer Frequency Measure Example

From Manuals

Compatibility Lincoln 60, Lincoln 60E

This example demonstrates how to use a timer to measure a signal's frequency. A test signal is generated by P0.6 (J2 pin 5) for P1.26 (J2 pin 17) to measure.

Please follow these steps to run the timer_capture example:

• 1. Compile the timer_capture example.
• 2. Program the Lincoln with the binary.
• 3. Connect J2 pin 5 (P0.6) and J2 pin 17 (P1.26).
• 4. Press the "RESET" button.
• 5. Enter a frequency to measure between 1 and 999 hertz.

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 following screen shot is of the timer_freqmeasure example in action.

The below signal was captured from P0.6 (J2 pin 5) after entering 500 for the frequency.
