Hi everybody

I am coming from freescale world and I want to switch to ARM controllers.

Does anyone know if ARM micros are able to refresh variable window while the firmware runs? (just like freescale HCS12 micros)

Example:

RUN/GO button is pressed.
Firmware is running.
Variable window refresh variables every 100ms.


If so what JTAG debugger I have to buy?

Thank you
Nikos

The ability to view memory while the processor is running is a feature of Cortex-M processors from ARM. i.e. it is not available in ARM7 or ARM9 parts.
