Re: [Flashforth-devel] Floating point library - open issues

[Mikael N. <mik...@fl...>]

There seems to be an issue with the NSTDIS bit in INTCON1.
FF PIC24 Interrupt routines rely on that nested interrupts do not 
occur.
Either there is some latent problem in FF or the float lib keeps 
resetting that bit.

There could also be some other conflict with the usage of the shadow 
registers between FF and the float lib.

If you use unbuffered transmission on TX1 you will experience less 
problems, since there are no
disturbing interrupts during the float calculations.

I will check details later.
