MIOS_HLP_Dec2BCD

[TK.]

Could you explain why the address to the high byte is moved from FSR0 to FSR2, and the FSR2 pointer incremented before reading?

Taking the information from the SDCC manual, I know the data should go into FSR2+2...So why the move from FSR0L? Perhaps that information in the manual is outdated? I was also wondering why you didn't just do PREINC0?

I started the wrapper at a time where this documentation was not available... so the approach was very easy: I compiled a dummy function with the same parameter list, and had a look into the resulting .asm file. I copied the generated code 1:1 to ensure that I don't oversee any side effects.

I think that the compiler uses FSR2 as a temporary pointer to ensure, that a function never returns with an unbalanced stack pointer in FSR0. However, for the C wrapper we have some potential for optimizations here - with the disadvantage, that there will also be a lot of additional debugging effort ;-)

Best Regards, Thorsten.

TK,

just wanted to add a final big thanks,

with the new wrapper 1.9a MIOS_HLP_Dec2BCD() works like a charm :D

Bye,
