Hi Vaclav,
I started to play with software I2C on 12F675 and found that TRISIO_bits definition is missing. Can somebody add following (or something similar) into pic12f675.h (and corresponding "volatile __TRISIO_bits_t .." line into .C file) ?
Included in r5287; I also consolidated the device libs for 12f629 and 12f675. I used TRISIOx rather than IOx as the bit names according to the data sheet.
Thank you for the report.
BTW, I tried following macros ( Raphael recommended them in 2007-12 ), but no success with the new SDCC:#define SETB(reg,bit) (reg) |= (1<<(bit)) #define CLRB(reg,bit) (reg) &= ~(1<<(bit)) #define LED1 GPIO,0 #define LED2 GPIO,2 SETB(LED1);I get following error (it looks like no expansion is done in preprocessor ? ) :main.c:100:17: error: macro "SETB" requires 2 arguments, but only 1 given main.c:100: error 20: Undefined identifier 'SETB'
Please find attached a working version of the macros. Basically you need two levels of expansion here: #define SETB2(reg,bit) (reg) |= (1<<(bit)) #define SETB(PIN) SETB2(PIN)Now SETB expands its argument and passes the expanded form ("GPIO,0") to the SETB2 macro.
Regards, Raphael
