Contents.Code Composer Studio (CCS)Code Composer Studio is a complete, Eclipse-based integrated development environment (IDE) that supports the LaunchPad ecosystem, as well as the rest of Texas Instruments' Embedded Processors portfolio. This tool enables developers to program, debug and compile code directly into your LaunchPad evaluation kits.When using CCS with a LaunchPad evaluation kit, CCS is free and fully-featured.(CCS for MSP430 LaunchPad is Windows only // C2000 LaunchPad supports both Windows and Linux)Compile & debug code for all LaunchPad kits with an intuitive user interface.CCS supports all LaunchPad evaluation kits and is updated frequently to ensure device support packages are up-to-date. CCS is available for Windows OS today.With CCSv5, the User Interface has been greatly improved and simplified offering an intuitive and easy development environment.With an updated compiler, developers are sure that the code being compiled is as efficient as possible without sacrificing performance.

Thanks Steve! Typically a UART is point to point. If you connect it to 2 devices you will likely have bus contention and even though the settings are invalid for one of the devices, it will try to interpret the signal and get corrupted data. The best option would be to select and MCU with 2 UART peripherals. Otherwise, you could probably use a mux to select which device you are communicating with. You would disable the UART, select a device using a GPIO, setup the UART and then start communicating. Stephen,Very good article.
I’m a top notch HW designer but not as qualified on software and RTOS which I’m trying to improve. I don’t understand why your option 3 says “Option 3: Use an external UART to USB converter”. There is a USB to UART converter on the 430G board, its the emulator, so why not use that, or am I not understanding something here.I have a msp4305529 and want to understand more how to really communicate through the UART rather than using energia or other libraries. Thanks for the question. You are correct, the board itself has a UART USB emulator.
I prefer not to use it because I have had issues with it in the past, especially on Linux. If you have it working with the onboard option than by all mean use that. I just wanted to point out that there are other options. The majority of the tutorial should be relevant to the 5529. There will be clocking and pin muxing differences for sure, but as far as UART is concerned, if you are using the same peripheral they likely function the same way. If you want to chat more about the UART-USB converter ping me at.
Simply Embedded is a website dedicated to teaching and collaborating on embedded programming projects. All of the projects will be completely free and open source, as will the development tools used. The first series is intended for those who have little experience with embedded software but have a decent understanding of the C programming language. It is a great resource for hobbyists, novice programmers, CS/EE students and hardware designers alike who could benefit from a better understanding of software. I encourage questions and discussions in the comments section and will be available to provide guidance along the way. The projects will be as real-world and practical as possible. The goal is to provide you with knowledge that is applicable to other projects and platforms.© 2015-2019, Simply Embedded Inc.
