I have compile with MikroC 5.01 to do testing with my PIC16F887 & RFID reader & 16x2 LCD display with following codes:
- CODE: SELECT_ALL_CODE
unsigned char uart_rd;
unsigned char data;
unsigned char temp[12];
unsigned char N = 0;
// LCD define
// Lcd pinout settings
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
sbit LCD_D7 at RB3_bit;
sbit LCD_D6 at RB2_bit;
sbit LCD_D5 at RB1_bit;
sbit LCD_D4 at RB0_bit;
// Pin direction
sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D7_Direction at TRISB3_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D4_Direction at TRISB0_bit;
void main() {
TRISC = 0x80;
OSCCON = 0x76;
OSCTUNE = 0x0F ;
ANSEL = 0; // Configure AN pins as digital I/O
ANSELH = 0;
C1ON_bit = 0; // Disable comparators
C2ON_bit = 0;
TRISB = 0;
PORTB = 0xFF;
UART1_Init(9600);
Delay_ms(100);
Lcd_Init();
Lcd_Cmd(_LCD_BLINK_CURSOR_ON);
Delay_ms(100);
do {
if (UART1_Data_Ready()){ //<------ Check if a character has been received before reading
uart_rd = UART1_Read(); // read the received data,
UART1_Write(uart_rd);
temp[N] = uart_rd;
N = N +1;
if (N == 10) // temp storing string
{
Lcd_Cmd(_LCD_CLEAR);
Lcd_out(1,1,temp);
N=0;
}
}
} while(1);
}
Everytime, I put near the tag, the LCD shows weird characters shown in the attachment below::
Please anyone can suggestion solutions ?
It's important to me because I'm dealing final year project now.
