Respected Experts, I am Ravikumar.N, working on 8051 microcontroller. I have an issue regarding the pulses of unknown frequency.
I am equipped with the following things: 1) I have an 8051 based development baord. 2)I have an unknown frequency source.
My Purpose: I want to measure the pulse width of the unknown frequency that will be fed to 8051.
My queries:
1) I dont know to which pin of 8051, these unknown frequency pulses has to be fed inorder to measure the pulse width. 2) Please let me know what logic has to be used to calculate the pulse width after these pulses(unknown frequenc pulses) are fed to an appropriate pin of 8051 microcontroller.Thanks In Advance, Ravikumar.N
