C LANGUAGE CODE PROBLEM
hi, I want to make the code below will in each condition will only execute printf 1 time. so how should I change it ?
thanks
while(1)
{
if((input(pin_a0)==1) && (input(pin_a1)==1) && (input(pin_a2)==1))
{
delay_ms(1000);
lcd_putc("\fPL available:0");
delay_ms(1000)...
mean I connect my db9 pin and usb to serial port converter to my laptop only? and using hyper terminal or real term to do the loop back test?
is it I don't need to connect my db9 pins to PIC ,if I short pin2 n pin3? thanks
Computer driver problem or voltage problem ?
I have programmed the right code to my pic16f877a, I can use putc/printf function but I failed to use getch function.
I couldn't receive any data from pc to my PIC16f877a when using my own computer but when I used my friend's computer, it can...
I have another problem is when I am using my friend computer , the data can be transmitted from pc to Pic but when I am using my own computer, it failed to do so. So probably what will be the problem? thanks
if this code is true
that mean in vb2008
if i write in this way, and make a button.
serialport1.wrte("1")
by clicking the button then the vb will send the "1" to the pic.
Unfortunately, it does not work. thanks
How can I transmit the data from visual basic 2008/ 2010 to my PIC16F877a?
I am using ccs compiler.
I can send the text from PIC16F877a to computer but I do not know how to send text from VB2008/2010 to PIC16F877a.
I need this urgently because whenever PIC receives the certain text from...
CAN ANYONE teach ME HOW TO SIMPLIFY THIS CODE? it is very messy. How if I have 100 parking lots.
I have no idea at all.
1 = available
0 = unavailable
I know how to declare the array
but I dont know how to insert it.
int8 x;
int8 y;
int8 plav[4];
if((input(pin_a0)==0) &&...
thank you for your help but my lectuere required me to use FOR WHILE, increment and decrements. if in VB I know how to do but this is c language , I have no ideas.
The design is I have 2 PARKING LOTS
if both of the inputs x and y = high
then z will show the number of parking lots now is : 0
Can someone teach me how to do this ?
I only know how to use the begineer method but don't know how to use
"For (z=0 ; z<3,z++ )" to complete the code
thanks
actually I have replaced the LDR(light dependent resistors) with the switches because the LDRs didn't work in PROTEUS 7.5.I don't know what caused the LDR failed to work.thanks
I have edited the code to this way and I used PROTEUS 7.5 TO RUN THE SIMULATION.
THE SIMULATION LCD RESULT CANNOT SHOW WHAT THE RESULT THAT I WANT. THERE ARE SOME UNWANTED CHARACTERS APPEAR.
IT IS MY CODE HAS PROBLEM ??
HERE IS MY CODE
#include "16f877a.h"
#fuses...
