pic 16f688

Hello every body: I just joint the forum. Switching now slowly over from Basic Stamp 2 to the pick micro. I have Basic pro Gold . I have programmed some 12f683 successful. However I started now with the pic 16f688 because I needed more I/O. And it has the same programming pin configuration then the 12f683 which fits my Omega prototyping board. My Problem is: Con fig file. Or addressing the pins correctly. Or both. Especial I don’t know if using eight. $00000000 is OK because it is not working. I understand port A and port B have only 6 Ports. This is my code: #CONFIG ifdef PM_USED device pic16F688, intrc_osc_noclkout, wdt_on, mclr_on, protect_off else __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_ON & _CP_OFF endif #ENDCONFIG ansel=0 'set i/o to digital cmcon0 = 7 'comparator off TRISC=%000001 ' set PortC RC5-RC1 to ‘outputs, RC0 input PORTC=%000010 ' Set PortC RC1 high to turn ‘on LED1 Main: ' *** Test the switch state *** if portC.0 = 0 then led2 'If switch is pressed then ‘jump to LED2 routine PortC.1 = 1 ' Turn LED1 on portC.2 = 0 ' Turn LED2 off goto Main ' Jump to the top of the main loop LED2: '*** Turn LED2 on *** portC.2 = 1 ' LED2 on portC.1 = 0 ' LED1 off goto Main ' Jump to the top of the main

This the way to display you code

Start by adding a PAUSE 500 after you turn the LEDs on and off.

Your LED is probably blinking faster than your eye can detect (or not leaving enough time for the LED to emit light).

Symbols in PBP have meaning that may be different than other languages, I. E. "C" .
% is used for binary, example %11111111 it does NOT use 0b00000000 or $00000000 as binary
$ is used for HEX , example $FF

If you don't want your pick to reset turn off the watchdog timer from configuration bits

Code:

---

__config_ wdt off

Thank you .

Sorry, I was not working for a long time and newer answered.

I Wiil TRY Thankyou

I changed the programm!
It compiles fine my
U2 programmer is working.

It compiles and programms fine in Micro Code Studio Plus
however no red light is flashing on the U2 programmer .

PS: my U2 programmer is working.

When I check the HEX. File in meProg.
red light is flashing on the U2 programmer
After programming the HEX. File looks different !

How is the programmer connected?

Robert

To avoid problems in the future:

http://www.picbasic.co.uk/forum/show...556#post127556

Also, use uppercase for DEFINEs.

Your config looks wonky.

__CONFIG _CONFIG1, cfg1

This looks like left-over from a copy&paste.

Thanks, i dd

if you load your (programmed as discussed) 16f88 into the u2 then use the "read" icon do you get results as per this attachment ?
can you erase a chip ?
can you verify a blank chip ?
can you reprogram chip and then verify it ?
