CC26xxWare Release Notes

Release date: August 4, 2015

New features

• [DRV_SRC] Event: Added functions to set and clear software events (EventSwEventSet, EventSwEventClear and EventSwEventGet).
• [DRV_SRC] AON_RTC: Added function AONRTCCurrent64BitValueGet(), returning the SEC and SUB_SEC registers as one 64 bits result.
• [DRV_SRC] CCFGRead: Added new module with a set of functions returning most of the CCFG bit fields.
• [DRV_SRC] CCFG: Add CCFG configuration option to use CACHE RAM as general purpose RAM (GPRAM) - (Choosing between having cache or having 8 K-bytes of extra RAM).
• [DRV_SRC] CCFG: Added ability to change the CCFG struct location. This is a special functionality needed only if executing entirely from RAM. Note that the prebuilt library is built with default CCFG location and will not work properly if CCFG location is changed.

Improvements

• [DRV_SRC] AON_RTC: Changed function AONRTCCurrentCompareValueGet() to avoid disabling interrupts.
• [DRV_SRC] General: Code size optimization of several modules.

Bug fixes

• [DRV_SRC] OSC: XOSC startup time calculation done by function OSCHF_GetStartupTime() returned maximum startup time too early.
• [DRV_SRC] CPU: Corrected compiler error when compiled with GCC.

Known Issues

• None
• For an updated list of known issues (including issues found after the release), see CC26xxWare on the Texas Instruments wiki.

Release date: June 11, 2015

New features

• [DRV_SRC] ROM: SW-based crypto functions in ROM are now available through DriverLib (see rom_crypto.h).
• [RF_SRC] Radio: Restructuring radio library: Moving rflib files to driverlib (prefixed with "rf_"), added rf_patches catalog (for RF patche files).

Improvements

• [DRV_SRC] General: Minor code size reduction in several module APIs by using bit banding when possible and replacing base address argument with a constant in single-instance modules.
• [DRV_SRC] General: Compiler specific defines are renamed to use compiler's own defines. gcc --> __GNUC__ , rvmdk --> __CC_ARM . Compiler defines 'codered' and 'sourcerygxx' are deleted.
• [DRV_SRC] setup: Some TI-RTOS power startup configuration is moved to trimDevice() to run pre-RTOS.
• [DRV_SRC] setup: Setup API now has a setup.h file which can be included instead of declaring trimDevice() as an extern explicitly. The setup API is added to the DriverLib HTML documentation.
• [DRV_SRC] AON_RTC: AONRTCStatus is split into AONRTCActive and AONRTCChannelActive for faster and more compact code.
• [DRV_SRC] AUX_TDC: Defines in aux_tdc.h now refer to defines from hw_aux_tdc.h to avoid magic numbers and make a stronger connection to register descriptions. All defines for start and stop conditions are renamed to match enumerations in register description.
• [DRV_SRC] AUX_TIMER: Defines in aux_timer.h now refer to defines from hw_aux_timer.h to avoid magic numbers and make a stronger connection to register descriptions.
• [DRV_SRC] AUX_WUC: Defines in aux_wuc.h now refer to defines from hw_aux_wuc.h to avoid magic numbers and make a stronger connection to register descriptions.
• [DRV_SRC] AON_EVENT: AON Event defines for event selection are renamed to better match register description enumerations.
• [DRV_SRC] CCFG: Cleanup in the customer configuration description (CCFG/ccfg.c)
• [DRV_SRC] hw_cpu: Removed obsolete file: hw_cpu_cc26xx.h

Bug fixes

• [DRV_SRC] General: Crypto and Flash APIs are updated to fix GCC compiler issue.
• [DRV_SRC] Event: Defines in event.h used for EventRegister() are deleted and instead the documentation describes how to select defines from hw_event.h and how to find valid pairs of event sources and event subscribers.
• [DRV_SRC] SysCtrl: SysCtrlSetRechargeBeforePowerDown() now uses C basic type arguments instead of enumerated types. Defines for valid arguments are added and documented.
• [DRV_SRC] SysCtrl: SysCtrlSetRechargeBeforePowerDown() is updated to configure recharge configuration slightly different, reducing maximum recharge period.
• [DRV_SRC] AUX_ADC: External ADC reference is not supported thus removed from AUX_ADC API.
• [DRV_SRC] AUX_ADC: AUXADCReenableInputScaling() is removed from AUX_ADC API and safe usage of AUXADCDisableInputScaling() documented.
• [DRV_SRC] AUX_ADC: Configuration of AUX ADC is changed into two steps so it won't be enabled until after configuration is done.
• [DRV_SRC] PRCM: PRCMWdtResetStatus() is removed since a WDT reset is no longer detectable after setting WR_TO_PINRESET bit.
• [DRV_SRC] Timer: TimerTriggerControl() is removed because it access functionality which is not supported.

Known Issues

• None
• For an updated list of known issues (including issues found after the release), see CC26xxWare on the Texas Instruments wiki.

• [HW_INC] General: Enhancing the hardware interface description (Removed description of register not recommended to be used by the customers and improved description of remaining registers and register fields).

Bug fixes

• [DRV_SRC] SysCtrl: Corrected bugs giving too high current consumption in STANDBY (Two bugs: 1: When running in External Regulator mode. 2: When having multiple events waking up from standby asynchrounesly).
• [DRV_SRC] AON_RTC: Enhanced reading of the RTC clock (Reading the RTC clock could be interrupted giving wrong result. Function AONRTCCurrentCompareValueGet() is now made thread/interrupt safe).
• [DRV_SRC] CTYPTO: Corrected minor bug in function CRYPTOCcmAuthEncrypt() results in sometimes giving wrong result).
• [DRV_SRC] SysCtrl: Added minor extension to battery monitoring function SysCtrl_DCDC_VoltageConditionalControl() (Do not changed DCDC setting before battery voltage measurement is available. This function is called regularly by TI-RTOS).

Known Issues

Release date: February 25, 2015

Bug fixes & New features

• cc26xxware_2_20_06_14829 is the initial revision and contains as such no bug fixes or new features.

Known Issues

• [DRV_SRC] - STANDBY current consumption when using external regulator mode
  The driverlib function used to setup the recharge rate before entering the STANDBY power mode does not turn off the adaptive rate calculation when in external regulator mode and ends up with minimum recharge rate and a current consumption of approximately 100 micro amps (while expecting approximately 1 micro amps).
