problem with SW from Keil-MDK

Hi,

First thank You for this nice piece of soft- and hardware.
I’d like to implement a Hough circle detection into the Pixy FW. As the first step I tried to rebuild the Pixi FW, but encountered slight problems ;).
I downloaded the last version from the https://github.com/charmedlabs/pixy (v.03) and build it according to http://cmucam.org/projects/cmucam5/wiki/Building_Pixy_Firmware.
Unfortunately I get this response after uploading the new video.hex to the Pixy (FW version incremented to check, if there is a change):

Pixy firmware version 1.0.2
CCB2 frame data

error: Communication error with Pixy.

Do You have a hint for me whats going wrong here.

PS:

IDE-Version:
µVision V5.11.1.0

Strange, I’ve changed the version to 0.1.45 and communication works with PixyMon version 0.1.49.
Any suggestions?

OK, got it working.
I had to build the PixyMon from the repository too:
About:
PixyMon version 1.0.1
Pixy firmware version (queried) 1.0.2

The PixyMon version 1.0.2 seams not to work with the repository FW.

Best regards,
Tom
