Hello ,
Very interesting. Thank you. I'm not a PBP user so I had no idea inserting an assembly code function into a PBP program was that easy. I suspect you're coding for an 18F which has RRCF and...
Here it is. It wasn't tested... ftw var long ; unsigned long ftw; // 32-bit Frequency Tuning Word f var long ;/************************************************************************ ;...
mikes quote here is very wrong from the manual the inflexible way
for control = 0 to 15 LATB.4=Control.0 LATB.5=Control.1 LATB.6=Control.2 LATB.7=Control.3 next control
Yes thanks, but how to step through the options in the most efficient way without disturbing ports B0-3
Yes, in XC8 that's how you would address the "local" variables (c, f, and n) using assembly language.
The ARRAYWRITE command prepends the LOOKUP or LOOKDOWN commands. b0 VAR BYTE b1 VAR BYTE Letter VAR BYTE[9] ARRAYWRITE Letter, ["SOMETHING"] FOR b0 = 0 TO 8 LOOKUP b0, [Letter], b1
I've looked at the examples and posts on here and they are helpful but..... OK I have a 38x25 display. I can talk to it using hserout and have a 1ms interrupt running so want to send it 1...
Mike, It can be almost copy/paste in PBP. I can try to sort details to work in PBP. But I don't understand what is calcFTW@c,@f,@n... Is it just variables declared in function? Can you explain?
If you are using PIC 18F, then use simplest solution is LATB.4=Control.0 LATB.5=Control.1 LATB.6=Control.2 LATB.7=Control.3 EDIT: For PIC16 PortBCopy var byte
