How do I read the value of a 4040 Counter connected to a PIC.THe connections are in an attachment.Any help is appreciated.

Does Anyone know how to interface a PS/2 Mouse to a PIC.I want to know if there is a way you can do it in flowcode.Can we use the UARTs for Mouse Data and Clock.

Hi can anyone give me a FCD file for 16f628.The current one does not support the TMR1 interrupt although it is available


Here is the details from the datasheet

7.0 TIMER1 MODULE
The Timer1 module is a 16-bit timer/counter consisting
of two 8-bit registers (TMR1H and TMR1L) which are
readable and ...

How do I take the value from timer1. and how do I reset it to zero.for timer0 if say tmr0 = 0; in C code it is working.But tmr1 is showing up as an error.

Thanks everybody.
I have finished the counter using the 74HC4040 as a precounter.I need to know how i can take the value out of the 16bit counter.I connected the last pin to it so that I can count fast and set it to increment on transition of the signal.Also how do I create a custom interrupt for ...

what if I use a high speed precounter like 74HC4040.It can count until 90 Mhz.If I can just contol the gate through a Schmitt trigger and read the values .It should do my job.I want to know how to read the input from 12bits of the counter.The problem is that if the frequency is high the counter is ...

Thank You.
But what should I do to count high frequencies.Also how can we create Interrupts for other pins .I am trying to control a Max038 with a PIC and count the value to get a good idea of PICs.My control system works but when the counter is in its loop.The buttons do not work.The Max038 ...

I am new to PICs.I want to make a simple Frequency Counter and display it on a LCD using a PIC16F877A and a 4Mhz Crystal.I want to know how to use TMR0 to do this.Please post a Flowcode file so that I can have a idea.Also how can you create a Custom interrupt for a random pin like RC0.I don't mind ...
