MSP430F2274: Where do I begin to configuring the microcontroller

Aditya Prabhu12

Part Number: MSP430F2274

Hey,

This is a very general question, so I apologize for that in advance. 

I am building a device for my lab where the device has to receive, transmit serial data in 10Hz; from a pressure sensor that i think is going to be via RS-232, and transmit the data to an antenna, and ten onto a tablet-like device. And, the device has to 'wake-up'  from a sleep state at anytime, wirelessly.

I have experience with using CCS on a TI-MSP432 Launchpad and Booster. Bu that was a board with a debugger, i'm not sure how to tackle just using a microcontroller, i'm pretty lost. 

There were a lot of options, but I chose the above mentioned microcontroller, since I need the microcontroller to draw minimal current at all times, so it has to be low powered; the communication protocol is flexible, and it was capable of UART and SPI, so i don't think that will be an issue. 

So, ive never had experince with this other than a university class. I googles a bit and saw that I need an 'Evaluation Platform' that is supposed to be a board that would allow me to write code for that family of microcontrollers, and i'm not sure but it should also program my microcontroller with the code that's needed to perform actions. and I assume that I can treat that just like the launchpad?

I could not find an actual device i can buy that is an 'Evaluation Platform', as described. 

Honestly, if you can give me a step by step approach to configuring a microcontroller(until soldering), or point me to a source that has this information(i haven't been able to find one), that would be great.

I know it's a lot to ask, i did not think I would be this lost.

    You might want to look into getting a launchpad with an integrated wireless transmitter like the CC1312 or CC1352.

    Once you have the application debugged wiht the debugger connected, you can pull all the jumpers and the debugging hardware will have no affect, you can even power it externally.

    Note that if the sensor is truly "RS232" you will need to use a level converter since RS232 voltage levels will damage an MCU.

    Hi Aditya Prabhu12,

    If you need an "Evaluation Platform" or EVM depends pretty much on how you imagine your development process. An EVM is a good choice if you want to do prototyping (e.g. by wiring up the EVM with a breadboard) and being able to easily replace an MCU (this can be a big advantage since burning up a controller while prototyping happens to the best of us...). The EVM for MSP430F2x devices can be found here: MSP-TS430DA38

    Opposite to an EVM, a LaunchPad typically comes with a built-on USB-Debugger / Programmer. While using an EVM you will need to have an additional programmer device, such as the MSP-FET. This is the device which connects the USB from your computer running CCS or any other programming/debug software to the JTAG port on the EVM used to program your microcontroller.

    There are also plenty of useful Application notes and user guides behind the links I provided above.

    For in-production programming of the microcontrollers on the finished boards, make sure the JTAG port pins are accessible.

    I hope that helps to get you started.

    Hi Aditya Prabhu12,

    I haven’t heard back from you, I’m assuming you were able to resolve your issue. If not, just post a reply below or create a new thread if the thread has locked due to time-out.

    Thanks and best regards,
    Max
