This are common outputs for all tested MCU's.
I have tested with 18, 28 and 40 pin MCU, i didnt get any error from ICD or from MCU but i can not run the program.
Program is compiler and writen to MCU but if i want to e.g. light the LED nothing happens. I use this demo board for some time now ( cca over 1 j.)
and i didnt have any problems till before few days.
I try to set jumper J6 and then you get some result but totaly wrong one.
E.g.
output_high(pin_b3) he lights B1 and B2.
THERE IS NO BAD Connections or missing ones!
Where to look ? |

1. Are you using the PicDem board, or PicDem2-Plus ?
2. Post the LED blinking program that you are using.
3. Post your compiler version. |

PLUS
2. Post the LED blinking program that you are using.
Non of the previus programs are working. LED was just a test..
I have used this demo board for over a jear with different programs.
#include <16F913.h>
#fuses XT,NOWDT
#use delay(clock=4000000)
#include "PICDEM_LCD.C"
void main ()
{
//lcd_init();
//printf(lcd_putc,"Test");
//delay_ms(2000);
while(true)
{
output_high(PIN_B1);
output_high(PIN_B0);
}
In this case i get B0 and B1 ( i have restarted the ICD few times ) but there is also B3 light switched ON. In second case i can get any display on LCD.
3. Post your compiler version.

Try the following test program. It should blink the LED on Pin B0.
I didn't test this in hardware because I don't have a 16F913, but I
believe it should work.
The PicDem2-Plus has an external 4 MHz oscillator (not a crysta),
so that's why I'm using the EC_IO fuse. Also, the LCD module must
be disabled to use Port B for digital i/o. Part of the LCD module
is disabled upon power-up, but not all of it. That's why I put in the
statement to disable it, below:
| Code: |
#include <16F913.H>
#fuses EC_IO, NOWDT, NOPROTECT, BROWNOUT, PUT
#use delay(clock=4000000)
void main()
{
setup_lcd(LCD_DISABLED);
while(1)
{
output_high(PIN_B0); // Blink the LED on pin B0
delay_ms(500);
output_low(PIN_B0);
delay_ms(500);
}
} |

I restarted whole thing ( ICD, picdem, mplab, new operating system ) one more time and now its much better like before and this is the case:
On 16f913
After compiling your test program B0 is blinking but the B3 is still ON.
On 16F877
After compiling just B0 is on, so this part ist ok.
//-----------------------------------------------------------
OK. So now i know its 16F913 program "error". But i dont get it why, becuse before cca 6 months i have tested this program without error ( with correct display).
void main (void)
{
lcd_init();
printf(lcd_putc,"PICDEM Test");
delay_ms(2000);
}
and now this is not working ? |
