Hi ra68gi,

I think i wanna have a look on your code as well.Is your code is an adaptation from "instant interrupt" which you mix with asm or else?Well,1x, 2x,4x resolution sounds great.It might be a choice which i will skip using PLD or CPLD to do the job.If this doesnt work then i will opt for 2 PIC18F4331 which is connected through I2C that will enable me to control 2 motors almost at the same time.

Talk about C,yes it's a great stuff.You just have to include the related <.h> file and tweak a bit in you code,and there you go.I think you could download sourceboost free?Or limited somehow.
