Need advice for creating nS time delay

[Acetronics2]

Hi, Sayzer

How are you ???

let's see ...

@ 20 Mhz ... a NOP is ... 1/ 5 Mhz = 200 ns ...

so, just insert, in your PbP program :

@ NOP ... and you get a 200 ns delay ...

You can try to Boost a 16F PIC @ 30 Mhz ... ( I've read about 32 Mhz ...)


With 18F series @ 40 Mhz , you will get 100 ns per NOP ... and it is a PbP DEFINE OSC ...

so, 2 or 3 NOP's will do it !

Alain

PS : No PIC solution @ 4Mhz ( minimum instruction time is 1µs ... )

But you can play with external logic gates ( if possible ...) and use their propagation time : time can easily fall to 10 nS ...
