| ICD-40 Needs to be uncoupled from USB |
 Posted: Mon Sep 05, 2005 12:32 pm |

I have to say that I'm just starting with PIC controllers, so may 'this question has been answered already many times.
I use a CCS compiler and a ICD-U40 programmer / debugger. I'm using my ICD-U40 only as a In CIrcuit Programmer. ( I haven't tried to debug with it jet)
Every time I program new code in my flash PIC and start the program, I have to uncouple my ICD_U40 from the PC before I can reprogram my flash PIC.
So everytime I change my sourcecode I have to unplug the ICD-U40 and plug it in again.
What goed wrong ?
I use the CCS version PCWH ( the windows IDE version) |

Give some more information about your hardware and firmware.
Do you download the code from CCS IDE or from ICD-U software?
Do you click "Start Program" button?
Do you have a reset supervisor chip connected to the MCLR of the PIC? Do you have a 47k pull-up resistor?
Also, it would be very helpful, if you post your *.h file with the fuses. Don't forget to use [code]. |

I use a ICD-U40 with firmware 1.39 #99 ( I can see that at the bottem of the ICD Control program V2.30
I program from this ICD Control program not from the CCS-IDE.
I certainly use the start and stop button, and sometimes it works, but mostly not.
My program is real simple I have a complete listing at the bottem of this page. It is nothing more than a blinking LED and I write some information (fixed & variable) to an LCD display, this program works.
I can reset with a wire to Vss ( I work on a breadbord) Pin not_MCLR/Vpp is pulled with a 27Kohm resistor.
I can't check my USB port, I don't have watchprogram or mini-tester for USB like I have for my RS232 port.
I'm starting with I2C that is why I include I2C, the program code doesn't use it (yet).
[code]
#include <16F877.h>
#device adc=8
#device icd=true
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=12000000)
#use I2C(master, SCL=PIN_B0, SDA=PIN_B1)
#include <lcd.c>
void main()
{
int a=0,b=0;
set_tris_a(0x00);
lcd_init();
delay_ms(10);
lcd_putc("\fLCD TEST HV1.0\n");
lcd_putc("Firmware FV1.0 \n");
delay_ms(200);
lcd_putc("\fhttp://www.\n");
lcd_putc("jordaantest.nl\n");
delay_ms(200);
while(TRUE)
{
delay_ms(400);
if (a==100) {b++; a=0;}
output_high(PIN_A0);
delay_ms(400);
output_low(PIN_A0);
printf(lcd_putc,"\fnumber: %x %x",a,b);
printf(lcd_putc,"\nnumber: %U%02U",b,a);
a++;
}
