Video: LCD cuam tshuam nrog 8051 (AT89S52): 4 Cov Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29
Nyob zoo qhov no yog pib ntawm 8051. LCD tuaj yeem ua haujlwm los ntawm 8-ntsis thiab 4-ntsis, tab sis hauv 8051 8-ntsis feem ntau yog siv, 4-ntsis siv thaum siv arduino, AVR thiab PIC. 8-ntsis hom txhais tau tias nws siv 8 xaim rau xa chaw nyob thiab cov ntaub ntawv.
Kauj Ruam 1: Cov Cheeb Tsam Yuav Tsum Tau:
LCD 16*2
Micro-maub los AT89S52
Crystal oscillator 11.0592MHz
Capacitor 10 uf
Ceramic capacitor 22pf
40 tus pin IC puag
Jumper Hlau
Potentio-meter 10k
Kauj Ruam 2: Teeb Kho Vajtse:
Kev kho vajtse txuas qhia hauv daim duab
Txuas qhov chaw nres nkoj 2 mus rau LCD cov ntaub ntawv pins.
Chaw nres nkoj 0.0 RS thiab Chaw Nkag 0.1 rau ENABLE.
RW rau hauv av.
Resistor thiab capacitor rau RESET tus pin.
Kauj ruam 3: Teeb Software:
Nruab KEIL4 ntawm koj lub PC
Program rau LCD cuam tshuam:
#suav nrog sbit rs = P0^0;
sbit ib = P0^1;
void ncua ();
tsis muaj dab tsi cmd ();
void dat ();
void lub ntsiab ()
{
char name [10] = "INSTRUCTABLES";
tsis kos npe rau hauv b;
P1 = 0x38;
cmd ();
P1 = 0x80;
cmd ();
P1 = 0x0f;
cmd ();
rau (b = 0; b <= 10; b ++)
{
P1 = npe ;
cov ();
ncua ();
}
}
tsis muaj dab tsi cmd ()
{
rs = 0;
ib = 1;
ncua ();
ib = 1;
}
void dat ()
{
rs = ib;
ib = 1;
ncua ();
ua = 0;
} void ncua ()
{
unsigned nyob rau hauv;
rau (a = 0; a <= 500; a ++);
}
Koj tuaj yeem rub tawm los ntawm no:
