Swordfish

thanks for clarifying.

i noticed there is no mention of static variables for subs, does this mean i have to use public variables or are all variables defined in subs and functions static?

i seem to remember reading that variable space was recycled.

funny you should say that i tried this in both work and vs2005 and it didnt work, so after you posted i retried and sure enough it worked some times but i had to start slecting on the text or it would delete the text unfortunately id also forgotten that vs2005 auto tabs. anyway i understand that thi...

Cunning!.

thanks for the explanation and the example.

where is the tabbing documented? its not a standard windows method. you guy's obviously love keyboard shortcut's, unfortunatly i dont unless its a single keystroke. also sometimes its nice to block comment out a largeish section of code and then go back and un comment a few select iles of code. this...

I would also like to say that i miss the block commenting, and also the block tabbing was nice too.

its now very tedious to make the code look nice if ive just added and ifthen around some existing code.

the jist of what i wanted to do follows. dim buttons as byte dim inputs as byte dim Index as byte dim multipleaxer as porte for index = 0 to 7 multiplexer = index delay(us10) buttons.Bits(Index) = portd.6 inputs.Bits(Index) = portd.5 next I should end up with 2 bytes of extra input information. woul...

thanks i dont know why i couldnt see it before.


do you mean code inefficient as in speed or code space? as speed is really not a problem for what i'm doing

Go on tell me what it does, quickliy looking at the instructions it would seem to generate a 5MHz clock signal which isnt much use to me. what i meant by jitter was the random variation between getting an external signal to trigger my code which isnt syncronus with the pics clock so the best i could...

is there an obvious way to indext through a specific byte with a variable?

like a bit array on a specific byte.

If anyones interested it was much easyer than i expected i did the following and the jitter is now 100us interrupt mytrigger() INTCON.4 = 0 'do this first '********************************************* DelayUS(5) For i = 1 To 4 FAST_GATE =1 DelayUS(2) FAST_GATE =0 DelayUS(3) Next '******************...

Well from the time of the Pin going high/or low (changing), it will take a couple of instructions before it will get to the part of your program that generates that delay. How many, I'm not sure, but it will be exactly the same each time (theoretically) There’s your first piece of code overhead. Pr...

what i need to do is trigger the code from an external source.

the pic only has one job to do and that is to wait for an input to change on portb.0,
i was assuming i could use interrupt on change, but i was wondering what the jitter was likely to be.

I need to make a simple pulse generator that takes an external trigger provides a delay and then some various trigger pulses, i've tried the following but i get about 500ns jitter @ 40mhz While TRUE While PORTB.0 = 0 Wend FAST_GATE =1 DelayUS(20) FAST_GATE =0 Wend would using interrups be a better b...

thanks again for the prompt reply
