The changes are described in mcuoneclipse.com/2013/02/08/zumo ... rdm-kl25z/
There is one thing which is related to the FRDM-KL25Z board: it does not generate the needed 5V for the shield from the battery voltage, so I had to add a voltage converter to the shield.
The other thing is that D4 on the reflectance array is connected to the NMI (Non Maskable Interrupt) line of the FRDM board: while it is possible to disable NMI in the startup code of the Cortex-M0+, because there is no pull-up on the sensor line, it could cause a NMI on the processor. So I re-routed that pin as supported by the reflectance sensor array.
The two above things are related to the FRDM board, and not a problem of the Zumo shield. But would be great if for example there would be traces on the board to make the add-on of the voltage generator easier.
The other thing is that the FRDM-KL25Z board has 3.3V voltage levels. The sensor array has 5V, and while some input pins are 5V tolearant, and to make the sensor response faster. Here again it would be great if 3.3V operation would be possible on the reflectance array (similar what is possible with the normal 8-sensor array you have in your shop which I use for other projects).
Many thanks to the Pololu team, and keep the excellent work going!
