problems with interfacing SKM53 GPS module & did i damage it when i did this wiring ?
Hi all
I'm a beginner in Micros and I'm facing a lot of problems with my SKM53 GPS (Datasheet) module:
1-I wired it the wrong way unintentionally, I connected VCC (5V) or GND (don't remember exactly) to TXD for a few seconds and then I noticed and disconnected it, Did i damage the module?
2- I've read that the standard NMEA baud rate is 4800, but in the datasheet provided above it says 9600, I wrote a program trying both of them but i had no output. I use UART module in PIC16f877a. I'm trying to show the position, velocity, time extracted from the GPS sentences on LCD, this is my code (which I think is completely wrong)
any help (and codes) would be appreciated :sad:

Code:
// LCD module connections
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
sbit LCD_D4 at RB0_bit;
sbit LCD_D5 at RB1_bit;
sbit LCD_D6 at RB2_bit;
sbit LCD_D7 at RB3_bit;
sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
char x[82]=" ";
void interrupt(){
if(pir1.b5==1){
uart1_read_text(x,"*",10);
lcd_out(1,1,x);
pir1.b5=0;
}
}
void main() {
intcon.b7=1;
intcon.B6=1;
pir1.b5=0;
pie1.B5=1;
lcd_init();
uart1_init(9600);
while(1){}
}any help (and codes) would be appreciated :sad:
