Can I add a PIC16F648A to device list for 3.147 compiler?
PostPosted: Mon Oct 13, 2003 8:33 am     Reply with quote

I'm using the CCS 3.147 compiler and want to switch from the PIC16F628A to the PIC16F648A which is basically the same chip with more memory. The F648A isn't in the device list to choose from. How can I add it? How do I create a header file?
Thanks.

The problem is not in the header (.h) file. The 16F628.h and 16F648a.h
files are very similar. The #device statements at the start of the files
are different. Also, the comments which describe the #fuses are
different. Here are the differences:

Code:
Comparing files 16F628.h and 16f648a.h
****** 16F628.h
//////// Standard Header file for the PIC16F628 device ////////////////
#device PIC16F628
#nolist
//////// Program memory: 2048x14  Data RAM: 223  Stack: 8
//////// I/O: 16   Analog Pins: 0
//////// Data EEPROM: 112
//////// C Scratch area: 77   ID Location: 2000
//////// Fuses: LP,XT,HS,EC,NOWDT,WDT,NOPUT,PUT,PROTECT,PROTECT_50%
//////// Fuses: PROTECT_75%,NOPROTECT,NOBROWNOUT,BROWNOUT,MCLR,NOMCLR,LVP
//////// Fuses: NOLVP,ER_IO,INTRC_IO,ER,INTRC,CPD,NOCPD
////////
****** 16f648a.h
//////// Standard Header file for the PIC16F648A device ////////////////
#device PIC16F648A
#nolist
//////// Program memory: 4096x14  Data RAM: 255  Stack: 8
//////// I/O: 16   Analog Pins: 0
//////// Data EEPROM: 256
//////// C Scratch area: 77   ID Location: 2000
//////// Fuses: LP,XT,HS,EC,NOWDT,WDT,NOPUT,PUT,PROTECT,NOPROTECT,BROWNOUT
//////// Fuses: NOBROWNOUT,NOMCLR,MCLR,NOLVP,LVP,INTRC,EC_IO,INTRC_IO,EC
//////// Fuses: NOCPD,CPD
////////

To add support for the 16F648A, you will need to change the Device.dat
file. If you have PCW, then you get a device editor, which allows you
to make these changes.
