Re: I/O Pin status during startup

Great !

just remember the processor does what you tell it ... and ONLY what you tell it ! ( thanks to God, PBP doesn't show too many bugs :wink: )

so, it's always you to set ALL the parameters,...

I'm starting a new series, with improved technique, and more detail on each step.

Re: I/O Pin status during startup

Greetings all,

first of all, thank you so much for all your help.

I tried moving the port settings before the Tris statement like you recommended and it worked!

the funny thing is I had added the port setting lines right before the TRIS statements for a run With MPLAB 8.92 sim ...

Re: I/O Pin status during startup

The important part is to set the PORT (or LAT) registers BEFORE setting the TRIS registers to outputs.
Otherwise the pins will be in output mode for a period of time but the outputs aren't specified.

Re: I/O Pin status during startup

did you simply try to add :

INIT:

PORTA=%00000000
PORTB=%00000000
PORTC=%00000000

Re: I/O Pin status during startup

before you go to too much trouble try what henrik suggests

clear all output ports before setting the tris registers and lose that delay in between

Re: I/O Pin status during startup

Hi Richard, thanks for the help.

Regarding the drawing...will try to get it and post here.
In the meantime here are the answers:

Re: I/O Pin status during startup

So, looking at your code....effectively it boils down to

TRISA = %00000000 ' This enables 23 of 24 output drivers, pins goes to whatever state PORT/LAT says
TRISB = %00100000
TRISC =...
