Hardware, Tools, and Toolchain This is Part 1 of a step-by-step guide to bringing custom microcontroller uc to life. Any help would be great.

You would then have a problem of converting from binary to bcd for use in the display. Discussion in ‘ The Projects Forum ‘ started by gcentauriJan 25, Jan 26, 4.

I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted! Potentiometer Questions Started by norbss Yesterday at Mar 24, 21, 2, Russlk New Member Dec 19, So my first project has been to try and make a 7-segment display count up from 0 to 9 using some kind of button press.

This was my first experiment with digital logic though, so maybe it will just make more sense as I work with things.

I’ve tried many different set-ups but haven’t had any luck.

Russlk New Member Dec 16, Replacing a 4 pin leaded inductor with a ddatasheet pin Started by gkmaia Yesterday at I hope I’ve described my situation well enough, I just can not figure out why the counter isn’t counting. Terminal count up pin 12 connects to clock pulse up pin 5 of the next stage. For a better experience, please enable JavaScript in your browser before proceeding.

Jan 26, 8. The count-down terminal is held high. To participate you need to register. Do you have LOAD pin 11 datashest high? You must log in or register to reply here. Jan 28, 9, When I flip the switch I know I’m getting a slow pulse maybe that’s the problem, if if so, is there a circuit I can build to make a quick single pulse?

I have read the data-sheets and read quite a bit on this forum as well, but nothing I try seems to work.
