Using the same simple program I have been using to teach myself Flowcode, I replaced the 16F88 with a 18F2580 (http://ww1.microchip.com/downloads/en/D ... 39637d.pdf).

When I try to compile to the chip I get this:

...
success

Return code = 0

Launching the programmer...
C:\Program Files (x86)\Matrix Multimedia\Flowcode V4\Tools\PPP\PPPv3.exe -cs 2 -chip PIC18F2580 -nogui "Flowcode1.hex"

(NOTE: if the PIC is code-protected, this message will be

That took 6.895 seconds

FINISHED

I also created a new program targeting the 2580. The program only had a begin / end. It also failed with the same problem.

(I also tried programming with the boards not connected and bypassing the flowkit)

I figured out how to get my PICKit2 connected. It was able to download the hex without a problem. After downloading I moved all of the jumpers back and the program runs, but the LCD display is messed up. It looks like "0 || || P || 0 ||...". The LED is running correctly. But I still can't use Flowcode to compile and download.

Hello,

Try disabling the extended CPU config setting. This should allow the LCD to work correctly.

[dbasnett]

So don't use Flowkit, compile with extended CPU = Disabled, and then download with Microchips PICKit2? Is this 'the' solution or just temporary?

[dbasnett]

Using the PICKit 2 with the change to the extended CPU seems to have cured the LCD on Port B.

My 4580 chip is in (I have to go pick it up), so if you want to pursue why I can't download with the Flowkit, it will need to be today. Hopefully I will not have any issues with the 4580.

Extended CPU
Looking through posts on here it looks like the best advice is unless you specifically need the extended cpu options is to have it turned off.

[dbasnett]

I have no idea what the option does. What I really need is to be able to download directly from Flowcode. Switching the jumpers around to download is OK for getting used to the system, but long run it isn't fun. I also worry about having the PICKit2 and USB cable accidentally connected at the same time.

Hello,

Do you have to switch the jumpers around? If you are not using PortB pins 6 and 7 in your application then you should be able to leave the jumper where it is and still allow the application to run, make sure the PICkit is not holding the device in reset. PICkit2 and USB cable both plugged in together should not cause any issues.

Have you setup Flowcode so it is using the PICkit directly or are you manually loading via PICkit each time. If you are doing this manually then here are the details for setting up Flowcode.

The chips should arrive today so I will see if I can get them to work correctly with the PPP software.
