I sow that when i put function display_LCD in interrupt , then i create this problem. I try to make a function delay in program .
void msdelay(unsigned int time)
{
unsigned int i,j;
for(i=0;i<time;i++)
for(j=0;j<2;j++);
}
but problem has not disappeared

about...
but this problem i sow on osciloscope in real time .
i use this library for interfacing LCD
void msdelay(unsigned int itime)
{
unsigned int i,j;
for(i=0;i<itime;i++)
for(j=0;j<2;j++);
}
void command() //comand functie definita
{
RA0=0;
RA1=0;
RA2=1;
msdelay(1)...
void LCD_D7()
{
LCD_D7 = 1; //Make D7th bit of LCD as i/p
RA2 = 1; //EN
RA0 = 0; //RS
RA1 = 1; //RW
while(LCD_D7){ //read busy flag again and again till it becomes 0
RA2 = 0; //Enable H->L
RA2 = 1;
}
}
result it there
Hi everyone. Can someone explain or show me example how i can interfacing LCd without using __delay library . Because __delays generate in my project the signal delay time that I do not need. I attach picture of the problem .
Hi. Can anyoane tell me how i can generate limited frequency between 310-630 rpm ? If i have 310-630 rpm in 0.2 second . Thank you forward . I use pic16f886 .
TRISB = 0x00;
PORTB =0x00;
T1CKPS1 = 1;
T1ckps0 = 0; //prescale 4;
T1OSCEN = 0;
TMR1CS = 0;
GIE = 1;
PEIE = 1;
TMR1IE =1 ;
TMR1ON =1...
I am a beginner in programming and microcontrollers but I would like to generate pulses with pic 16f886 to 310-630 rpm in the period 0.2 second. Can help me ? . Thank you forward.
