Gpio ? Trisio ?

[ultiblade]

Hi there,

I'm kind of stuck on this. A few weeks ago i made a RC5 IR to 10F202 receiver. All
worked fine. I decided that i need to store some counter values in eeprom, since the
10F does not have that, i decided to go with the 12F519.

I was used to set the IO functionality for the 10F trough the GPIO and TRISIO registers:


TRISIO = %00001000 'GPIO.3 = input only
GPIO = %00000000 'All low


In the 12F519 datasheet is says the tri-state register is called TRISGPIO and the GPIO register is called GPIO.

When i use TRISGPIO i get an syntax error, using TRIS or TRISIO also.
When i set a pin like: SDA VAR GPIO.1 i get an error : undefined symbol 'GPIO'

What am i missing ?

I think i figured it out, but i'm still confused ...

When i compile :


TRISB = %00111100 'Set TRIS register input's & output's
PORTB = %00000000 'Set all digital low

SDA var PORTB.0 'I2C DATA pin
SCL var PORTB.1 'I2C CLOCK pin


It compiles, without any errors !
How ?

Change your PIC type to 12F519 in the menu above the program.

Thought of that, checked just yet it is 12F519 ... So that's not it ....

Hi,

Have a look to the "1xYzzz".bas file in your PBP Directory. ( 1xYzzz = 12F519, here )

You can modify it or add Other Aliases ... at your own risks !

You're so right !

Thanks, all clear now !
