#118410 - what does "below" mean Responding to: ???'s previous message |
The LPC931 gets an external clock signal (below 7MHz) on the XTAL1 input. I want to determine the clock frequency of this signal
If you want to measure a frequency on a "random" pin, you need a frequency that is, at least, 10 times lower tham your clock. However, if you connect the external clock to a timer input, you can measure a frequency up to the capability of the timer input (see datasheet). So, I suggest you connect the external clock to the T0 or T1 pin. Erik |
