Recently I develop one project in which total 5 DC motor. The project contain 16x2 LCD display with PIC16F886. When use press key then motor will run. I observe that after some key operation LCD show garbage & it remain few minute. LCD runs in 4 bit mode. Garbage comes randomly some times for 3...
Hi Brian,
Thanks for your reply. Yes I have a 10K ohm resister across the RA3 and GND. When I press the switch RA3 will connect to the GND and when I release it will be connected to VCC through 10KK.
The Logic I need is the when I press the button RC0 should come on for 10 sec then it should...
Hi All,
I have written simple code to blink an LED when switch is pressed. But problem I'm facing here is when I press the button LED is going high but it is not turning off after 10sec delay. Please let me where is the problem in the below code. I'm using CCS C compiler and here RA3 is defined...
Hi All,
Thanks for your valuable reply. I will try to do the coding without using ISR for external interrupt. I will post the latest status. Thank you all
Hi
I'am very new to the PIC programming. I have written a program to give 20 min of delay when an switch is pressed. I have connected an switch with active high signal to the INT pin of the PIC16F676 pin and I have connected an buzzer to RC1 port, connected a transistor to RC5 port to turn on...
Hi All,
I'm going to use pic16f676 in my new project. I want small conformation on timer. Is it possible to generate 20 minuts of dalay suing PIC16F676 IC. If yes plz provide me the sample code for this.
Thanks,
Manjunath
Yes I am using external crystal also I have connected the 22pF capacitors across the crystal.

But I am continuously writing the second line of the LCD then it should display later right....? mean aster some 100mS...
Hi All,
I have connected the MCLR pin of PIC16F877A to VCC through 10K ohm resistor, but when I turn on the MCU the LCD is not displaying the second line until I touch the MCLR pin to GND point through a wire if once I touch then it will work properly until net power though main. Can any one...
