Basic help for 12F629

[BobK]

Hi Gene,

I was looking at the PBC manual on the MElabs website. Here are some examples of setting the ports. You will also need to have a copy of the 12F629 datasheet to get the register information.

Symbol PortA = 5 'Define PortA register location 
Symbol TrisA = $85  'Define PortA direction register location  
 Poke TrisA,0  'Make all PortA pins outputs 
 
 
 Peek PortA,B0  'Get current PortA pin states to variable B0  
 Bit1 = 1  'Set Bit1 in B0 which will become PortA pin 1 high  
 Bit3 = 0  'Set Bit3 in B0 which will become PortA pin 3 low  
  'Bit0, 2 and 4 will remain unchanged  
 Poke PortA,B0  'Send the new byte to PortA to complete the change
 
 End   

5.23. POKE

POKE Address, Value

Writes Value to the PICmicro MCU register at the specified Address. Special PICmicro MCU features such as A/D converters and additional I/O ports may be written using POKE. POKE is a PICBASIC™ Compiler statement and is not supported on the BASIC Stamp. (See PEEK for more information.)

Poke $85,0 'Write 0 to register hexadecimal 85 (Sets PortA to all outputs)

I also just finished looking for some older examples of programs I wrote in PBC but they are at home on my older computer so I don't have access to them until this coming weekend.

You need to look at the READ.ME file that came with your compiler program to check and see if the 12F629 will work with PBC. I didn't see it in the manual's list. You may be wasting your time with this chip if its not supported!

HTH,
