#186015 - Re: Power Miser
Responding to: Erik Malund's previous message
I have been looking at the Silicon Labs C8051F985 and C8051F983 "ultra low power" chips (w/ 2k and 4k Flash, respectively), either of which should suit my application well. And so I have also been looking at the manufacturer's development kit (C8051F996DK) for these chips.
Can I use ALL of the port pins on the Target/Prototyping PCB included with this kit, or are there components or direct connections on the PCB that interfere with using all port pins freely? (As seems to be the case with the ToolStick Daughter cards?).

I was also looking at the ToolStick Base Adapter/Programming Adapter which works with these chips. Seems like it would be nice to be able to program the chips this way... but if I were going to be programming the MCU and then placing it directly into a prototype, then it seems that it would be better to design the prototype board so that I can program the MCU in-circuit. And if I can program in-circuit, then I could also do all debugging (stepping, break points, etc) of the MCU while it is in the prototype... Just like with the evaluation boards, correct?
So I can just buy the USB Debug adapter and use it with my board? Is it pretty straight-forward to do so?
