Question about the IDE and include files....
PostPosted: Wed Jul 31, 2013 11:25 pm     Reply with quote

Hello.

I must say I'm new to using the IDE from CCS, I almost 99% of the time use MPLAB.

I'm trying to use the option in the IDE that generates include files (structs and variables).

After it generates the include file I saw that for the TxCON registers it generates the same name for different registers.

Code:

#word MCU_T1CON = 0x104
#bit    MCU_TCS = MCU_T1CON.1

#word MCU_T2CON = 0x110
#bit    MCU_TCS = MCU_T2CON.1


#word MCU_T3CON = 0x112
#bit    MCU_TCS = MCU_T3CON.1



Shouldn't the IDE generate different names for the different registers, maybe MCU_TCS1, MCU_TCS2?

Maybe I'm missing some feature on the generating part (this is for a 24FJMC101).

Thanks in advance.

Use of register names and bits is rarely needed, and generally discouraged. I'd suspect that you have found a fault in the generation, that no one else has found, because they never use it.....

In general, 99% of register/bit accesses, are now never wanted, because the compiler handles the functions for you. This ability was left present for the few 'old/odd' occasions where an antique program wanted these. Most such programs would pre-date the PIC24, and having multiple TCS bits.

Report the duplication to CCS.

If you want for a very few bits to use names, then use the SFR name ability instead (getenv). I'd doubt is 1 in 1000 of the 'old hands' with CCS, ever use the automated register naming now.

Best Wishes

Thanks Mr. Ttlemah for the super-fast response. Will report this to CCS.

Did not know this "getenv" thing (I'm kinda bad with C), but will use it. Got your info here: http://www.ccsinfo.com/forum/viewtopic.php?t=50698&highlight=getenv

Thanks.
