Hi all

I was wondering if anyone could help me with the following issue:

I have FLowcode V5 for the PIC's. I am struggling to get my PICKit3 to work with Flowcode in Windows 8. My previous laptop (windows 7, 32 bit) worked perfectly, but has unfortunately packed up and I have no option but to use my new laptop which is 64 bit Windows 8. I keep getting the following when I try and program a PIC directly from Flowcode with the PICKit3...



Launching the programmer...
C:\Program Files (x86)\Flowcode\v5\Tools\PICkit3\PK3CMD.exe -P18F43K22 -FWaterLevel.hex -E -M -Y
Return code = -1073741515

Flowcode was unable to transfer the flowchart to the microcontroller. Check the programmer options and physical connections.


FINISHED

This issue is getting a little urgent and would appreciate any help.

Incidentally, I have exactly the same problem with my desktop computer that runs Windows 7 in 64bit mode.

I really think that this issue has something to do with the 64bit mode of windows. I can't imagine that I'm the only one with this problem considering that both my computers are giving me the same error. I've tried running Flowcode as an administrator, but still no luck.



Many thanks in advance

HI
A couple of things can you program a hex file to chip using the pickit3 as a standalone programmer(if so we know the pickit3 works.
try this thread as your parameters dont look right

Hi dazz,

The PICKit3 works perfectly with mplab X on my new laptop. So I'm 100% sure it's not the PicKit 3 that's faulty. Definitely a setting or something that has changed between my old laptop and new.

Is there anyone using a PicKit 3 with windows8 to program a pic using ICSP? Maybe I could compare settings?

Did you have mplab 8.xx on your old system? There could be a dependency on it being installed.

Also, is the PICkit set to mplab mode? See this message.

Sorry i forgot to add the link, kersing has kindly provided it

Hi gents,

Thanks for all this info. I will definitely give that a try tomorrow. It is quite strange that the PK3 worked 100% with flowcodeV5 on my older laptop without these settings. At least I am able to program the PIC using ICSP with the .hex file that flowcode generates by importing it into MPLAB X so I can get the job done, just a bit cumbersome needing 2 programs to do the job when a month ago flowcode did everything. I'll let you know what transpires. And thanks for taking the time to help a newbie to flowcode like myself.

Hello,

I found that the newer stand alone PICkit 3 tool came with a new PICkit OS which meant it no longer worked with my version of MPLAB or the command line tool that Flowcode uses. I went back to the older version of the tool, downloaded the older firmware and it then worked correctly again.

Also note the newer version of the tool is very buggy (crashes all the time on my PC and hangs when you try and close it) and has a very restricted device set as apposed to the older version.

See this topic for details.
