Scoreboard using PIC16F628A
Scoreboard Test
This project is a continuation of a project I left from college. The hardware that was used before was basically the same with these except that we used PIC16F877A during that time which is a 40 pin microcontroller. In this version I squeezed all the juices from a 18 pin PIC16F628A. Two 3-to-8 decoders was used to multiplex the 13 seven segments. An 8 bit serial in parallel out shift register was used to display the values in the seven segment. The most unusual part is that instead of a normal 4×3 keypad requiring 7 I/O pin, in this proto type I only used 4 I/O to scan the keypad.

master tiktakx, may dinedevelop akong scoreboard ngaun.. kaso 877a gamit ko.. balak ko sana mag628a na lang din.. may copy ka pa ba ng schematic mo? tnx tnx.. hehe..
kahit part list na lang kung wala kana copy. hehe. tnx tnx.
thanks po in advance…^^
@newbie: sorry pero hindi ko po muna ilalabas ang schematic at code nito dahil template ko ito sa isang commercial project
hello po! ang ganda po ng gawa nyo, nkakainget!
pde po bang patulong po ? kase po scoreboard din po ung project namen sa isang subject pero PIC16F84a po ung gamet. sana po mtulungan nyo po ako!
@regine
kahit PIC16F84 kaya ito, just multiplex the seven segments using shift registers
madali lang ito
