HI, i need to make an up/down counter using a pic12f609 to sn7447 BCD to 7-segment display to count from 0 to 9 and 9 to 0
The control of the counting cycle must b done using two switches
switch 1 = Up (0-9)
switch 2 = down (9-0)
the delay time is 1.5 sec using mplab assembly language
am new to micro controller and i need some ideas to do this task . i have done this using 4-bit counter and bcd to seven segment display i just inverted QA an QD on the 4-bit counter using a Nand gate and D/U on the 4-bit counter is high to count from 0 to 9 and for 9 to 0 i connected the D/U to low . but using pic12f609 i have hard time writing a code for that ...
