em dùng mikroC for arm viết chương trình cho con LM3S8962 test cái lcd16x2. chỉ dùng cái sample code của nó, thay lại chỗ định nghĩa chân cẳng nhưng bị lỗi không dịch được, trong khi để như cũ thì ok.
em chỉ sửa đoạn này
thành thế này
Code:
// LCD module connections
sbit LCD_RS at GPIO_PORTD_DATA.D7;
sbit LCD_EN at GPIO_PORTD_DATA.D6;
sbit LCD_D4 at GPIO_PORTD_DATA.D5;
sbit LCD_D5 at GPIO_PORTD_DATA.D4;
sbit LCD_D6 at GPIO_PORTB_DATA.B4;
sbit LCD_D7 at GPIO_PORTB_DATA.B5;
sbit LCD_RS_Direction at GPIO_PORTD_DIR.D7;
sbit LCD_EN_Direction at GPIO_PORTD_DIR.D6;
sbit LCD_D4_Direction at GPIO_PORTD_DIR.D5;
sbit LCD_D5_Direction at GPIO_PORTD_DIR.D4;
sbit LCD_D6_Direction at GPIO_PORTB_DIR.B4;
sbit LCD_D7_Direction at GPIO_PORTB_DIR.B5;
// End LCD module connections
char txt1[] = "mikroElektronika";
char txt2[] = "Stellaris";
char txt3[] = "Lcd4bit";
char txt4[] = "example";
char i; // Loop variable
void Move_Delay() { // Function used for text moving
Delay_ms(750); // You can change the moving speed here
}
void main(){
Lcd_Init(); // Initialize LCD
Lcd_Cmd(_LCD_CLEAR); // Clear display
Lcd_Cmd(_LCD_CURSOR_OFF); // Cursor off
Lcd_Out(1,6,txt3); // Write text in first row
Lcd_Out(2,6,txt4); // Write text in second row
Delay_ms(2000);
Lcd_Cmd(_LCD_CLEAR); // Clear display
Lcd_Out(1,1,txt1); // Write text in first row
Lcd_Out(2,4,txt2); // Write text in second row
Delay_ms(2000);
// Moving text
for(i=0; i<4; i++) { // Move text to the right 4 times
Lcd_Cmd(_LCD_SHIFT_RIGHT);
Move_Delay();
}
while(1) { // Endless loop
for(i=0; i<7; i++) { // Move text to the left 7 times
Lcd_Cmd(_LCD_SHIFT_LEFT);
Move_Delay();
}
for(i=0; i<7; i++) { // Move text to the right 7 times
Lcd_Cmd(_LCD_SHIFT_RIGHT);
Move_Delay();
}
}
}
