Need Help : STC89C52 Blinking Led Program through STC-ISP Software

[Ahmar-47]

I wrote a program in C using Keil here is the code
#include <reg51.h>

sbit led1 = P2^0;

// Function to generate a delay in milliseconds
void delay(int ms) {
int i, j;
for (i = 0; i < ms; i++) {
for (j = 0; j < 1275; j++) {
}
}
}

int main() {
while(1){
led1 = 0x01; // Turn on the LED (set P2.0 high)
delay(500); // Delay for 500 ms
led1 = 0x00; // Turn off the LED (set P2.0 low)
delay(500); // Delay for 500 ms
}
}
The i generate Hex file upload that hex file in STC-ISP software as i have attached Screen shot it shows that chechking target mcu it stucks here i resest the board by clicking on reset button again its stuck on chechking target mcu i donot know whats the problem

Check if the microcontroller is responsive. Try to upload a simple LED blink code.

Perhaps you should try looking at the code he's already posted?

led1 = 0x01; should read led1 = 1;

 

[Nigel Goodwin]

led1 = 0x01; should read led1 = 1;

1 is decimal, 0x01 is hexadecimal, both are one and identical.

Yes I know, but maybe the compiler don't.
Sometime the usb gets loose enough that the system sees it, but it will not function correctly when trying to use it.

Yes the Problem is solved not the code error but somehow driver issue
