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:
' Name : BLINK3X2.pbp
' 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
' Keywords : FOR NEXT
' Description : PICBASIC PRO program to blink 3 LEDS in sequence.
' 16F877
' Define LOADER_USED to allow use of the boot loader.
' This will not affect normal program operation.
'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
