| Watch Window shows '.' for Array values; should be 0. SOLVED |

MPLAB IDE / PCM 4.060 / ICD2 / PIC16F690-ICD / TELEBYTE 245
Here is an image of the screen. Get485[8] is the array I'm having trouble with. I set it to 0 in this case, and other values previously. It will only show '.' or garbage characters such as 'd', '@'. It was working fine 2 days ago.
Here is the screenshot of the problem:
Array201 works perfect! It will change and show the correct value in the Watch Window.
I've been at it for about 1.5 days and am frustrated. Thanks A lot!

If you want us to look at it, you need to post a test program.
For example, in this thread I've post a little test program to show
how to step through source code in MPLAB.

If you can post a short little program like that, and demonstrate
the problem, then I can test it. |

Here is the test program:
| Code: | #include <16F690.h> //Include PIC16F690 header file
#device adc=10 //Configures the read_adc return size. 10 will return the full A/D reading of 10 bits.
#include <STDLIB.h> //Include general purpose standard library
#include <stdio.h> //Include standard input/output header
#include <stdlibm.h>
#include <string.h>
#fuses INTRC,NOWDT,NOPROTECT,BROWNOUT,NOMCLR,BROWNOUT,NOIESO,NOFCMEN,PUT
#use delay(clock=2MHZ,int)
#use rs232(baud=9600, xmit=PIN_B7, rcv=PIN_B5, enable=PIN_C1, ERRORS, stream = Network) //Set Slave address here. //Initializing the hardware UART, the PIC refers to it as EUSART, TX=xmit=PIN_B7, RX=rcv=PIN_B5, Enable Pin=direction control,FORCE_SW
//The enable pin C1 controls the direction of data transfer. It is needed for RS485 Two-Wire.
#rom 0x2100 = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}//0x2100 is for 16F-series PICs
char Array201[27] = {0x01,0x64,0x16,0x00,0x00,0x44,0x26,0x49,0x00,0x00,0x01,0x20,0x41,0x41,0x04,0x2E,0x00,0x01,0x20,0x20,0x20,0x00,0x02,0x01,0x17,0x00,0x1A}; //Response - Identify Sub Array - Opcode 201 - C9(h)
char GetIn485[8]={1,2,3,4,5,6,7,8};
void Network_fputc(char c) //Code from PCM Programmer
{
fputc(c, Network);
}
void main()
{
while(1)
{
delay_ms(80);
printf(Network_fputc, " Hello World! "); //Code from PCM Programmer
}
} |
The values show correctly in the hex and dec columns, if I enable them in the watch window according to the advice I received from the microchip forum: (pardon my run-on)
http://forum.microchip.com/tm.aspx?m=315144&mpage=1&key=񌾋
Here is a screen shot of the result:
Should I just rely on the values in the hex and dec columns? That is fine with me, if necessary. |

I'd say it looks like your problem is that the data type for the array is
probably set to "ASCII." Right-click on the array and go to properties -
then select whichever type you're expecting from the "Format" pulldown
(in the "Watch Properties" tab).
