TI Home > Digital Signal Processors and ARM Microprocessors >MSP430_Driver_Library 1_60_02_01 Digital Signal Processors Software TI Embedded Software Products All TI Developer Network Products Back to Software Folder ABSTRACT This guide book is a valuable quick guide to find important resources for MSP430™microcontrollers (MCUs). The scope of this training academy is on the I2C initialization, operation, and interrupt handling portion of the code examples. Some of the libraries are also "official", from TI. Changing clocks is often done on the MSP430 so that you can balance processing speed against long battery life. In both examples, the MCU is configured as I2C master. Implements repeated start. The code size is small, so that this solution can also be implemented on low memory footprint MSP430 MCUs. The library inherits from the Stream functions, making it consistent with other read/write libraries. Each communication protocol has its own advantage and disadvantage. The code examples and the SMBus library can be implemented in different derivatives of the same family with little effort; and they can be migrated to other MSP430 devices with the same SMBus/I2C interface with some considerations such as pin usage, memory and timeout-timer availability. This application report uses the MSP430FR2311IPW16, which integrates a hardware I2C module, to communicate with MSP430FR2111IPW16. MSP430 Graphics Library 1. 20. Let’s focus on the I2C part for now and learn using I2C protocol in MSP430 Launchpad. 91. SMBus is used as a communication link for smart batteries, power-related devices, and a wide variety of other system devices. - plentyofbytes/MSP430-I2C Along with Travis's recommendation, please refer to SLAA734 for suggestions regarding typical MSP430 I2C communication issues. jbandener / msp430_lib Public Notifications You must be signed in to change notification settings Fork 1 Star 4 Wire Library (I2C) Overview This library allows you to communicate with I2C / TWI devices.

Wiring Language/Library Reference The interface to I2C bus only uses two GPIO pins, which are quite flexible for users to choose. The software solution supports transactions on the I2C bus with an SCL clock frequency up to 100 kHz for master and slave. These functions are used in applications where processing-intensive transforms are done in real-time for minimal energy and with very high accuracy. For example, in one of the later lab exercises, you will see how you can change the clock source for the TI MSP430 microcontroller. Logic analyzer or oscilloscope screenshots would be particularly helpful, the issue could range from the wrong slave address to improper pull-up resistor values. 09 Release Notes Document Revision: 090513. From the README: Features Small. The MSP430™ SMBus Library is a royalty-free set of API's that provide support for master and slave protocols in a SMBus communication system. External components attached to the I2C bus serially transmit and/or receive serial data to/from the eUSCI_B module through the 2-wire I2C interface. When the receive parameter is set to I2C_TRANSMIT_MODE, the address will indicate that the I2C module is in receive mode; otherwise, the I2C module is in send mode. This application report describes design considerations when using the MSP430 Graphics Library, and provides an example of implementation and SMBus ) using the MSP430™ microcontroller I2C peripheral.
