    Problem with lcd-jhd162a !!!!!!!

    Ya... i never gave vdd and vss in reverse... but i did give 5volt dc to pin3 of lcd... which i now..know , should be given less than 1volt. my Crystal freq is 20MHz... give me some basic display programs.. i will check with my lcd...Thanks :) ---------- Post added at 22:05 ---------- Previous...

    Problem with lcd-jhd162a !!!!!!!

    i went through the link... was very useful to understand lcd. But, now pinout voltages from PIC MCU for lcd are... 0 5.12 0 0.05 0 0 0.5 0.4 0.4 0.5 0.5 0.4 0.5 0.5 5.12 0 but wen i check voltage at 16 pins on lcd panel.. it is : 0 5.09 5.03 4.99 4.99 0 4.99 4.99 4.99 4.99 5 5 5 5 5.09 0...

    Problem with lcd-jhd162a !!!!!!!

    this part of code initializes lcd... but i don't know wats wrong??? send_config(0b00000001); //clear display at lcd send_config(0b00000010); //Lcd Return to home send_config(0b00000110); //entry mode-cursor increase 1 send_config(0b00001100); //diplay on, cursor off and cursor blink off...

    PIC 16F877 data logger - need help!!

    i am working on a data logger, that senses temperature & humidity. also need to alarm if values cross a threshold. i plan to use 16f877 for this, is it okie?? and use lm35 for temp sensing . wat to use for humidity sensing(cheap IC)?? it's an academic project..wish to complete within 2...
