# MSP430 DriverLib 2.70.00.08

## Release Notes

Document Revision: 032416.1646

## 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.

- 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

- driverlC:\ti\msp\msp430_driverlib_2_20_00_06\driverlib_2_20_00_06ib.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.

- FRAM_configureWaitStateControl API in MSP430FR5xx_6xx family signature has changed to exclude the manualWaitState parameter since this register bit is now a reserved bit.

- 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.

## Installation and Usage

Generally DriverLib is installed as part of MSP430ware. If you wish to update DriverLib from the zip file, unzip msp430_driverlib_x_xx_xx_xx.zip in your MSP430Ware installation. The installation contains the driver library core as well as peripheral examples and API documentation.

After installing MSP430Ware or Driver Library restart Code Composer Studio. When opening CCS you will be greeted with a window like that shown below:

## Validation Information

## Upgrade and Compatibility Information

Steps to upgrade from Driverlib 1.90 to Driverlib 1.95
1. All projects that use driverlib should work as is when you replace the existing driverlib by Driverlib 1.95.
2. Some of the source and header file names have changed to be in line with the new Texas Instruments coding guidelines. However as long as the user includes "driverlib.h" instead of individual peripheral header files, the user will have no issues upgrading.
Steps to upgrade from Driverlib 1.60 to Driverlib 1.70

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

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.
As part of our continued process of optimizing MSP430 driverlib and standardizing the MSP430 driverlib APIs we have segregated the MSP430 modules into

- ‘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.

MSP430F5xx_6xx

- DMA
- FLASH
- MPY32
- PMM
- RAM
- SFR
- SYS
- UCS

MSP430FR5xx_6xx

- FRAM
- MPY32

## Examples

The examples may be built with either IAR, CCS or GCC. To build the examples navigate to examples/<family>/<peripheral>/<ide> and double click the .eww project files for IAR, import the .projectSpec file for CCS or run a "make -f " for the GCC makefile..

Current supported families are found in the Device Support section of the release notes.

Current supported peripherals are found in the Peripheral Support section of the release notes.

## Known Issues

- Asserts in CCS work only when the project is optimized for size
- EUSCI_A_UART_CLOCKSOURCE_ACLK/UCSSEL__ACLK do not exist for MSP430FR4133. Previously defined header files used these defines. EUSCI_A_UART_CLOCKSOURCE_MODCLK/UCSSEL__MODCLK have been added to the header files. Please update your user code, if they have the older defines and hence fail to compile.
- MSP430FR2xx_4xx driverlib and header files previously had references to XT2 defines. MSP430FR2xx_4xx devices do not support XT2. These references have since been removed. If your user code uses these defines please remove them.

## Versioning

This is build 2.70.00.08 of MSP430 driver library.
