Hi George,

congratulation, you won the award for the most awkward code :-)

Typically on 8051 projects 16 bit increment only needed to access external memory or lookup tables. And then "INC DPTR" can be used.

Also I believe, 0.99$ was not the single quantity price for the MSP430F149.

Such unfair comparison methods I know only from advertising departments.


Moreover you push the accu, nevertheless, if it was needed later or not.

In my experience the more compact code was generated with some registers as scratch pad (e.g. A, B , DPTR, R0 ... R7) only for using, never for preserving.
And every function, which need variables for longer time, must save they in the direct RAM. This is also the secret, why the Keil C51 was the most efficient in code and data size and in speed.
Only on interrupts every used register must be saved.


Nevertheless, it sounds interesting, that now the MSP430F149 and the XA also available as Flash.
Is it really available or only as development samples or only announced ?

Is the MSP430F149 really so hungry (250mA = 0.25A) or mean you 250µA ?

P.S.:
The 51 never die, see Dallas, Cygnal, Atmel newest products. So there is a life beside the 51, but not after it.
