12f609

[Macgman2000]

Does anyone have a picbasic template for 12F609?
I want to use the device with MCLR as input, not as MCLR. Also 8Mhz internal oscillator and set all remaining ports to outputs. I have tried a bunch of things and none worked. I am using the latest and greatest compiler. So I scrapped it all and want to see if anyone has used this chip body?

Any help is very much appreciated.

If you meant a template for the configs ...
There is a "template" for every chip, located in the PBP folder.

For a 12F609, open the 12F609.inc file and you should see this ...
If you are using the default PM assembler, they are the blue ones.
If using MPASM, they are the green ones.

I am seeing strange behavior with the 12F609. I have a start up port toggle to let me know it is going through the code. When it gets to the debugin I can't seem to make the ports work.



INCLUDE "Modedefs.Bas"
@ DEVICE PIC12F609, MCLR_OFF, IOSCFS_8MHZ, INTRC_OSC_NOCLKOUT,protect_off



GPIO = 0
TRISIO = %001100

'TRISIO.0 ' Output
'TRISIO.1 ' Output
'TRISIO.2 ' Input IR module input
'TRISIO.3 ' Input turn off MCLR
'TRISIO.4 ' Output
'TRISIO.5 ' Output



DEFINE DEBUGIN_REG GPIO ' Set as software RX in
DEFINE DEBUG_BAUD 1200 ' Set bit rate
DEFINE DEBUGIN_BIT 2 ' Set GPIO bit 2
DEFINE DEBUGIN_MODE 1 ' Set Debugin mode: 0 = true, 1 = inverted


; VARIABLES
Payload VAR byte
pause 100 ' pause holds up startup initialization for programming


pause 1000
GPIO = %010001

pause 1000
GPIO = %000000

pause 1000
GPIO = %010001

pause 1000
GPIO = %000000



main:

debugin [wait (255), payload]
select case Payload
case 0 'All stop
GPIO = %000000

CASE 10 'Right spin
GPIO = %100000

CASE 50 'Left spin
GPIO = %000001

case 100 'Straight
GPIO = %010001

END SELECT
goto main

Analog pins ...

ANSEL = 0

[Bruce]

Insert DEFINE OSC 8 when using IOSCFS_8MHZ

[Macgman2000]

Bruce nailed it. The ANSEL is superceded by the TRISIO according to the datasheet on all outputs, except for inputs where ANSEL is needed. I guess PBP was having timing issues since the define osc 8 was not declared.

Shouldn't that result in an error though? I can't see where you would want to let the compiler have opposing declarations.

Thanks guys!!!!
