4mhz to 8 mhz

[FRANCISCOGIM]

If you put your oscillator of 4 and put DEFINED OSC 4 or put an oscillator, 8 and put DEFINED OSC 8 nothing happens A pause 100 will be the same in both cases.
You must match the external oscillator with the definition put that in the compiler.
You can not put an external oscillator of 4 and set in compiler one of 8 that does not work well.

What about PULSIN and PULSOUT

would their resolution be doubled?

EDIT: Disregard...wrong post...

Only in versions 7.61 and up. The manual has a good list.

I have PICBASIC pro version 2.47 . version 7?

The manual talks all about how PAUSE, PAUSEUS, PULSIN, PULSOUT, SERIN/SEROUT (software based UART type commands), and various other commands are affected by changes in actual oscillator speed and the DEFINE'd oscillator speed. (i.e. faster oscillator, faster this, slower oscillator, slower that).

PBP compensates for different DEFINE'd speeds (i.e. SEROUT using 2400 baud will be 2400 baud if you DEFINE OSC 4 or DEFINE OSC 40), but can't do anything about what you put into the OSC1/OSC2 pins or what, if anything, you end up selecting for the actual oscillator frequency, either internal or external types.

Thanks skimask!
