The application PCB uses AT89C51IC2 microcontroller.
In setting up the in system debugger in the micro vision IDE,
I am getting an ISD51 monitor error There was no reply from the target system.
I pasted the following function in the file with main:
#include "ISD51.H"
void Init_UART (void) { T2CON = 0x34; /* Use Timer 2 For Baudrate */
RCAP2H = 0xFF; RCAP2L = 0xD9; /* 19,230 Baud @ 24MHz */ SCON = 0x50; /* Enable UART */ EA = 1; /* Enable Global Interrupts */ }
I set the COM port number to where the RS232 cable is connected to my laptop. (COM4) Baud rate=19200.
I have ISD51.A51 file in the project. I call ISD_check in the forever loop in the main function.
What do I do about this error? Thanks, Priya
