PulseOut

[JB]

Hello everyone,

simple question, about PulseOut syntax

Syntax : PulseOut pin, time units
"The PulseOut command will set the specified pin high"

what about the Pin is already high
does the PulseOut will set the pin low and return to high

and can the time units be in fraction of us (1 / 0.5 / 0.2 )

looking to use this with a PIC18F06Q41 @ 64Mhz to get a pulse of ~ 0.625ns (Low and High)

Thanks to all.

Test the state then,
If high.. use PulseOutInv. If low.. use PulseOut.

Thanks

PulseOut is a macro with a minimum time val of 1 microsecond. However, to get what you need ASM can be inserted into the following code as shown below.

#CHIP 18F46Q71, 64
wait 100 ms
Dir PortC.2  OUT

' ----- Main body of program commences here.
do
   set PortC.2 on
       nop
       nop
       nop
       nop
       nop
       nop
       nop
       nop
       nop
   set PortC.2 off
       nop
       nop
       nop
       nop
       nop
       nop
       nop
loop

This will give you 625ns on and 625ns off @ 64Mhz

I'll give it a try and post the results,

Hi, tested with 18F14K22 64Mhz (still wait for 18F46Q71)

worked fine nice signal ~65ns

Thanks
