alphanumeric lcd as counter

Posted on Feb 4, 2014

The communication technique with the LCD is the same like the last lesson, and for the current experiment we have added a counter which counts between 0000 and 9999. Our counter increments with 1 second delay. /* ` <7465> * ` Lesson nr. 16: ` Alphanumeric LCD as counter mode. ` Done by: ` Aureliu Raducu Macovei, 2010. ` ` In this exper

iment we will work with alphanumeric LCD. Communication ` with LCD will be performed through 4-bits and connections is made as ` follows: D4 with RB0, D5 with RB1, D6 with RB2, D7 with RB3; ` RS with RB4 and EN with RB5. ` To make this project more interesting, a counter is added ` (counts from 0000 to 9999) with a delay of 1 secunde. ` Test configuration: ` MCU: PIC16F628A ` Test.
