    Timer with pic12f675 and mikroc problem!

    Dear Susan, Thank you for your precis answers. This program is very simple and if I wanna explain it, so it is generator of an A-stable (Square wave ) that we can set on and off state duration with switches connected to GP1 and GP2 and Potentiometer connected to GP0. GP3 is for starting...

    Hi all, I am new in micro controller programming. I decided to make a timer with external trigger(if external command continued we have square wave). problem is when I change pot connected to micro I should wait one cycle to change time. for this aim I used time interruption but there was no...

    [SOLVED] How to collect parallel data from one port of microcontroller and show to 7segments

    Thanks Brian, 1- Yes I pull-down them by resistor connected to ground. 2- Yes two 7-segent are common cathode. 3- I wanna display decimal (00-63) 4- Yes right I forgot that, the code is : //-------------- Returns mask for common cathode 7-seg. display unsigned short mask(unsigned short num) {...
