I am really interested in custom timing and I am trying
to observe how it works, but unfortunately it does not work.

The existing code does not generate any signal on pin A0. Why? The oscilloscope is connected to pin A0. Enable code: T1CON = 0x79; // Start timer with Internal clock source, prescaler = 1:8 INTCONbits.PEIE = 1; // Enable peripheral interrupts INTCONbits.GIE = 1; // Enable global interrupts PIE1bits....

Hello everyone, I didn't get any signals on pin A0. Can anyone help me? What is the mechanism of the custom code? T1CON is the register where I select the prescale bits, but where are the postscale bits selected? What is the register for setting the final value? Here I found the custom code: https:/...

Thank you very much, it worked.

Hello everyone,
I tried to make a custom TMR1 for PIC16F877A and visualize the signals on pin A0 on the oscilloscope, but it doesn't compile.
Can anyone help me? I'm using Flowcode 10.

Hello to everyone, The program sequence must run only once in the loop. I have the values ​​key = 0 and key_ = 0 in the loop, but errors appeared and I did not understand why. In the test in this example I have key_ = 0, I write the key_ value to address 2, read address 2 and return the value in key...

Hi WingNut,
Thank you very much! It was in my eyes, but I couldn't see it.

Where are the options to thank users? I don't see them.

As I mentioned before, the program works, I did the test on a 24LC512 eeprom and a PIC16F877A microcontroller.
Thank you to Mr. Martin for his involvement and the help that did not take long to come from him.

Hi Martin,
It works perfectly, I'll come back later with a more concise flowchart, I have to delete the components that I no longer need.
