Silicon revision of the TM4C123GH6PM in the TM4C123GXL Launchpad

Hi, how do I know the revision of the µ-controller in the TM4C123GXL Launchpad? This is what is written on it:

     YFF
TM4C123G
H6PMI7
4CAR0TW
     G4

Knowing the target #define would help too.

Regards,

Angelo

    Hello Angelo

    The "I7" on the 3rd line would mean Industrial Temp Grade Revision 7

    Hi Amit, in this case the silicon revision will be TARGET_IS_TM4C123_RB0 or TARGET_IS_TM4C123_RB1 depending on the revision counting starting at zero or one. Which one should I use?

    Thanx,

    Angelo

    Hi Amit,

    Interesting, I am using TivaWare_C_Series-2.1.1.71 and the targets defined in the ROM are the following, from the rom.h:

    // This is part of revision 2.1.1.71 of the Tiva Peripheral Driver Library.
//
//*****************************************************************************

#ifndef __DRIVERLIB_ROM_H__
#define __DRIVERLIB_ROM_H__

#ifndef DEPRECATED
//*****************************************************************************
//
// ROM selection labels changed between TivaWare 2.0.1 and 2.1.  The following
// labels are intended to ensure backwards compatibility for applications
// which have not yet been updated to use the replacement labels.
//
//*****************************************************************************
#ifdef TARGET_IS_SNOWFLAKE_RA0
#define TARGET_IS_TM4C129_RA0
#endif
#ifdef TARGET_IS_SNOWFLAKE_RA1
#define TARGET_IS_TM4C129_RA1
#endif
#ifdef TARGET_IS_SNOWFLAKE_RA2
#define TARGET_IS_TM4C129_RA2
#endif
#ifdef TARGET_IS_BLIZZARD_RA1
#define TARGET_IS_TM4C123_RA1
#endif
#ifdef TARGET_IS_BLIZZARD_RA2
#define TARGET_IS_TM4C123_RA2
#endif
#ifdef TARGET_IS_BLIZZARD_RA3
#define TARGET_IS_TM4C123_RA3
#endif
#ifdef TARGET_IS_BLIZZARD_RB0
#define TARGET_IS_TM4C123_RB0
#endif
#ifdef TARGET_IS_BLIZZARD_RB1
#define TARGET_IS_TM4C123_RB1
#endif
#endif

    I downloaded what seemed to be the latest Tivaware C version from http://www.ti.com/tool/sw-tm4c

    As you can see it lacks the TARGET_IS_TM4C123_RB2 target. Is there a newer version?

    Hello Angelo

    You may use TARGET_IS_TM4C123_RB1. The next version will have the update for inclusion of TARGET_IS_TM4C123_RB2
