MSP430 DriverLib  1.80.00.18

Release Notes 

Introduction

This is the MSP430 Peripheral Driver Library. This peripheral driver library's intent is to allow application development at an API level instead at the device register level.   Allowing developers to concentrate on their applications instead of the nuances of the particular MSP430 device they are using.

Revision History

• Improved RTSC support. Driver Library projects added to New Project Wizard and Project Template.
• Energia support
• Removed baseaddress parameter in core peripherals. Provided backward compatibility through compiler define DRIVERLIB_LGEACY_MODE. For more information view the Upgrade and Compatibility Information section.
• Removal of baseaddress removes support of Grace 2.20.02.32. Users that rely on Grace should not update Driver Library at this time until a new Grace is released.
• Red Hat MSPGCC Support
• Removed deprecated 5xx_6xx folder support
• Code metrics added to documentation
• Workaround added for compiler warnings in older device header files
• Fixed various spelling issues in user's guides
• Bugzilla issue (5781) fixed - DAC12_A_init()  ignores outputSelect argument.
• Bugzilla issue (5347) fixed - SD24_B_configureConverterAdvanced() code fixed.

• Added RTSC support. This allows better discoverability by Grace and some basic documentation in the Eclipse help system.
• Added P2 update support. Driver Library can now be updated through CCS.

• Fixed issue with C++ bindings
• Fixed bug with USCI_A_UART recieveData, transmitData, transmitBreak that used the wrong type of register access (16 instead of 8)
• Fixed bug with USCI_B_I2C enableInterrupt, masterSingleReceive that used the wrong type of register access (16 instead of 8)

• Fixed include path in example projects to refer to driver library copy in workspace instead of from the installation
  
• Minor updates to inc/hw_memmap.h for each supported family

• Added C++ bindings to all driverlib peripherals
• Improved User's Guide Documentation
• Improved Release Notes Format
• Converted CCS examples to use CCS projectSpec
• In all driverlib code examples, the source and header files are now copied into the project and not linked (unlike previous driverlib releases)
• Examples generated from .projectspec file instead of .cproject/.project files
• Clear LPM5 bit for GPIO settings in all Wolverine examples
• Fixed Bug 4537- Set enable bit on ADC to 0 before turning ADC on or off in ADC12_B_enable and ADC12_B_disable
• Fixed Bug 4579- Changed comment in MPU_createThreeSegments() in MSP430FR5xx_6xx, MSP430FR57xx families
• Fixed Bug 4568 - Lock CS modules after unlocking in MSP430FR5xx_6xx, MSP430FR57xx families
• Removed (E)USCI_A_UART_init() and (e)uart_baudrate.h/c files in all families. Please use (E)USCI_A_UART_initAdvance() instead. The values to be written into the clockPrescalar, firstModReg, secondModReg and overSampling parameters of (E)USCI_A_UART_initAdvance() should be pre-computed and passed into the initialization function. http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSP430BaudRateConverter/index.html helps pre-compute the necessary values.
• Removed busy bit checking for all FRAM peripherals

• Fixed Bug 4591 - EUSCI_B_I2C_masterSendSingleByteWithTimeout() timeout incorrect
• Fixed Bug 3856 - The following AES256 API for MSP430FR5xx_6xx are removed AES256_decryptDataUsingEncryptionKey, AES256_startDecryptDataUsingEncryptionKey, AES256_generateFirstRoundKey,AES256_startGenerateFirstRoundKey. Two new API are added - AES_setDecipherKey, AES_startSetDecipherKey 
• Fixed Bug 4452 - Need FLASH apis that unlock info memory
• Added version.h to indicate driverlib version no.
• driverlib.h file is now available in every supported device family. Including this one header file in applications is sufficient for using any driverlib API call. Including driverlib.h eliminates the need to include "inc/hw_memmap.h" and every single "peripheral.h" the user would like to use. 
• Driverlib code examples copy the driverlib source and header files instead of linking them
• Removed deprecated 5xx_6xx examples. All customers should be using the new family based structure for driver library development. Please refer to the family's user's guides for new APIs.
• EUSCI_SPI, EUSCI_I2C, EUSCI_UART APIs are deprecated. Please use EUSCI_A_SPI, EUSCI_B_SPI, EUSCI_B_I2C, EUSCI_A_UART APIs for EUSCI operations.
• The deprecated EUSCI_SPI, EUSCI_I2C, EUSCI_UART APIs are removed for MSP430FR5xx_6xx family.

• Changed some remaining UART APIs to use C99 types
• Fixed minor doxygen documentation for CS
• Fixed bug in GPIO_interruptEdgeSelect that caused it to fail to work with even ports (P2, P4, ..)
• Fixed bug in COMP_E that accidentally clears the previous settings in CECTL2
• Fixed bug in ADC12_B_memoryConfigure that did not allow enabling the window comparator
• The header files have been updated to be in sync with CCS5.5 Beta
• FRAM_configureWaitStateControl API in 5xx_6xx family now ignores the manualWaitState parameter since this register bit is now changed  to a reserved bit. The API signature has not changed to maintain backward compatibility..
• FRAM_configureWaitStateControl API in MSP430FR5xx_6xx family signature has changed to exclude the manualWaitState parameter since this register bit is now a reserved bit.
• PMM_lockLPM5() API is used in MSP430FR5xx_6xx examples to disable the GPIO power-on default high-impedance mode to activate previously configured port settings. 
• Comp_E examples in examples\driverlib\5xx_6xx\comp_e will fail to build due to a bug in the existing device header file for versions of CCS less than CCS 5.3. To workaround this, please upgrade CCS or replace the msp430fr5969.h from the CCS5.3 release in your CCS install.
• Comp_E examples in examples\driverlib\5xx_6xx\comp_e will fail to build due to a bug in the existing device header file for versions of IAR5.5. To workaround this, please replace the msp430fr5969.h from deprecated\msp430fr5xx_6xx_header_files\IAR from the in your IAR5.5 install.

• Added TIMER_X_counterGet to get the current count of the timer

Validation Information

Upgrade and Compatibility Information

1. Add compiler define DRIVERLIB_LEGACY_MODE
2. Include "driverlib.h" instead of individual module header files ( eg. fram.h, wdt_a.h etc.)

• ‘CORE’ modules  - those that would have ONLY one instance of the module in a single device.
• ‘PERIPHERAL’ modules – those that could have multiple instances of the module in a single device.

This would reflect as the baseaddress of module being absent/present in the module driverlib API based on if the module is a core/peripheral. This change increases performance in some APIs and allows greater software standardization across MCU platforms in TI’s portfolio. We believe this also increases readability by removing an extra parameter in APIs for peripherals that will only have one instance.

Based on this rule, we had to change some of the existing driverlib APIs to remove the baseaddress parameter. This would break compatibility for existing customers.

To provide backward compatibility 

1. We will provide a compiler define DRIVERLIB_LEGACY_MODE. If this is predefined in the compiler settings, the older APIs will work (Pre 1.70 Release).
2. The user must also include  the “driverlib.h” header file released in 1.60 driverlib onwards instead of the individual header files.  

If DRIVERLIB_LEGACY_MODE compiler define is absent, then the newer APIs take effect (Post 1.70 Release).

Without making the above change, most existing projects that rely on driverlib 1.60 or below will fail to compile by default. Adding the compiler define DRIVERLIB_LEGACY_MODE and including “driverlib.h” instead of individual header files is necessary to get the projects to compile in legacy mode(using the older APIs). 

We advise newer projects that are in the process of development to adopt the newer APIs. The older APIs are still available in the deprecated section. Here is the affected peripheral list.
