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
I've been running the demo project from C:\Keil_v5\C51\ISD51\Examples\Generic_8052\ISD51_Demo
I only have the application PCB, I don't have an eval kit.
I set the target to AT89C51IC2, CLK frequency to 40MHz, I included #include "reg51rb2.h" to test.c.
The demo project builds. When I run it, I am getting the no reply from target error.
It is asking me to check the COM port, linking, ROM content and baud rate.
Can you please offer some pointers?
Thank you, Priya
