I believe that one of the cores in the 54102 has a FPU baked in. What sort of penalty does the firmware take, wrt size, when including the FPU libraries?

The R-2R Resistor Ladder DAC works well:

FYSA, I confirm that Win7 Pro X64 doesn't auto-resolve the drivers for the LPC11U37 ARMstamps.

I just installed the NXP driver installer (linked to on earlier pages - lpc_driver_setup.exe).

Same worked well and enabled connectivity with production ARMstamps from BT, and otherwise.

As info, I ripped out of NXP expresso stuff, the lib files for the 824. It is unaltered/unfettered - I just extracted it from a much larger set of device libs, given NXP presumably hasn't done so overtly. I offer it herein as this might be useful to others who may choose to pursue ARMbasic developme...

Copy all. Thank you, sir. Enjoy your day!
