USB U2 Not programming ?


Any body knows please Help:
PS: My first languish is German
typing on a German keyboard


I have installed :


PBP #3 Gold
Micro Code Studio Plus V 5.0.0.5
Compiler V PBPX 3.0.6.4
MPLAB IDE V 8.85


Programmer : USB U2 melabs 4.5. Firmware 5.9
Chip Target info ID 09A4 (16F877)


My problem started when I tried toprogram PIC16F88.


So I went back to BASICs:
I use the USB U2 melabs with a LAB-X2from meLAB
Chip is 16F877-20/P .
Yes power is supplied to the LAB-X2
My programmer gets power from a poweredUSB Port


My program is blink3x2 from meLABsample library for the LAB-X2
When I go [program compile inMicro CodeStudio] it appears every thing is fine however
the red programming LED on the U2Programmer is not flashing !
And I don’t get the desired resultson the LAB-X2


When I program from the meLABProgrammer it appears to program just
fine [the red led isflashing].unfortunate I don’t get the desired results on the LAB-X2.
Except now the hex code is changed!

Code:

' Compiler    : PICBASIC PRO Compiler 2.6
' Assembler   : PM or MPASM
' Target PIC  : 28/40-pin PIC types compatible with LAB-X2 board
' Hardware    : LAB-X2 Experimenter Board
' Oscillator  : 4MHz external crystal

'Define LOADER_USED 1

 i Var Byte   ' Define loop variable
LEDS Var PORTB  ' Alias PORTB to LEDS
   TRISB = %00000000  ' Set PORTB to all output
mainloop:
   LEDS = 1           ' First LED on
   Pause 500          ' Delay for .5 seconds
   For i = 1 To 2     ' Go through For..Next loop 2 times
     LEDS = LEDS << 1 ' Shift on LED one to left
     Pause 500        ' Delay for .5 seconds
   Next i
   Goto mainloop      ' Go back to mainloop and blink LED forever
   End
