Forget the Arduino IDE! I would recommend using Visual Studio Code with the C/C++, Arduino and Cortex-Debug extensions.
The Raspberry Pi Pico acting as programmer-debugger is called Picoprobe. It also features redirection of the Serial1 port.
The installation process is detailed at the earlephilhower/arduino-pico page. You may need to build OpenOCD with specific options. It is easy and works fine.
Debugging is performed from Visual Studio Code. Obviously, you can use manual command-line GDB and OpenOCD. The only caveat is Serial1 should be used instead of Serial to print to the console.
Please find some pointers below.

At USD4 apiece, you can use the second Raspberry Pi Pico as a programmer-debugger. It works really well!

Thank you for the pointer to the Challenger RP2040. It is nice to see the designers refrained from reinventing the wheel and took the Feather form-factor. Same for the LTE (SARA-R410M) or the WiFi radio (ESP8265).
The Raspberry Pi Pico RP2040 is a very good board and I strongly recommend the Earle Philower's Pico core for Arduino over the official Arduino mbed-based implementation.
There is a whole eco-system built around the Raspberry Pi Pico with many interesting kits. Let's me mention the E-Paper Display Pico Kit (EPDK), an all-in-one e-paper kit from Pervasive Displays.
 

Hi All,
I cleaned up the site last week. This year has not been the greatest for me(and for alot). Pardon the neglect. True that the blog has not been update, but I have not seen much content on the MSP430/432. Also TI's E2E has been vastly popular.
There was no "commercial" side. I still pay for server and forum licenses out of pocket.
I've kept it up since there is alot of useful info and people benefit from it.
 

Thanks, for the feedback.
I have already implemented the fixes based on your findings and planning for an update release of this package.

You could use a library designed for Arduino.
See 
Porting an Arduino library to Energia

@Abdul400 There is no need to post the same question multiple times, as already at 
 Please refer to:
Netiquette for Newbies Porting an Arduino library to Energia  
 

It looks like that the compiler setting for the large memory model is not set correct.
can you open the platform.txt file in
c:/users/johnw/appdata/local/energia15/packages/energia/hardware/msp430elf/2.0.7/platform.txt
and change line 21 from
compiler.mlarge_flag=-mlarge -mcode-region=upper
to
compiler.mlarge_flag=-mlarge -mcode-region=either
 

You can use a library for Arduino and adapt it to the MSP430.
Porting an Arduino library to Energia

Please have a look at 
Information to Provide When Asking for Help I²C Check-List I guess you're using the MMA8452 on I²C.

The RAM of an MCU can’t be expanded. Go for another LaunchPad with a more capable MCU.  

When using the latest version of Energia the wire (I2C) has now the function
setClock
to set to 400k use setClock(400000UL);

Yes, this is a bug, sorry a feature of the MSP-EXP430G2ET!

I'm going to assume you want to actually learn, and not just be handed "the answer."  Take a look at this on stackoverflow, it should help you figure out a solution your problem.

I'm receiving many mails about the libraries I've developed and I'm sharing.
 
The libraries are plug-and-play as I'm using them in my projects. However, they are designed for a specific configuration. For example, a SD-card library requires a minimum of 512 bytes of RAM as this is the size of a sector. So it won't work on the MSP430G2553.
 
With so many LaunchPads, BoosterPacks and components possible combinations, the one-fits-all approach is just impossible. It would end with lengthy and hard to read code with many pre-processing statements. For example, changing the pins names for the pins numbers improves the portability of the library across the LaunchPad range of boards.
 
Even if the library works out of the box, they are provided as examples and require some work from the user. This is the best way for learning. The user should read and understand them, and then customise them so they can match his/her exact needs.
 
With new hardware and software releases coming out, a library may suffer from obsolescence. It used to work with a prior version but no longer works with the new one. For example, each new release of Energia or CCS adds new features and some times modifies others in order to ensure compatibility across the whole range.
 
Finally, feel free to improve and share back the libraries with the community
 
This is a cross-post with Stellarisiti.

Use `setModule()` as described in https://github.com/energia/Energia/blob/master/hardware/lm4f/libraries/Wire/Wire.cpp#L599
 
void setup() { Wire.setModule(3); Wire.begin(); ... } Similar logic applies for UART and SPI.
 
As an alternative, declare the variable as in https://github.com/energia/Energia/blob/master/hardware/lm4f/libraries/Wire/Wire.cpp#L161
 
TwoWire Wire2(2);

Please find a library for the I


INA219_Distribution206.zip

Please refer to Wire.cpp#L121-L123
I2C_Params_init(&params); params.transferMode = I2C_MODE_BLOCKING; params.bitRate = I2C_400kHz;  

" Multiple libraries were found for..."
You've got a configuration error message.  Time to read the docs on porting from other libraries.
How-To: Porting Libraries Posting a Library for Energia Some Misconceptions about Libraries The above may provide guidance.  I am not able to help much beyond this suggestion as I'm deeply involved in other non-coding projects at this time.

Certificate fixed.
Thanks.

Not yet, stay tuned!

The CC1310 LaunchPad has a sub-1 GHz radio.
On Energia,
Install the EasyLink library by calling the menu Sketch > Include Library > Manage Libraries..., then select EasyLink and click Install. Select the board CC1310 LaunchPad. Call the menu File > Example > EasyLink > EasyLinkTX for the transmitter example. Call the menu File > Example > EasyLink > EasyLinkRX for the receiver example. Both examples work together. Obviously, you need two CC1310 LaunchPad boards!

It was important to be sure, as the standard uploader DSLite doesn't work on macOS 10.14 but used to work on macOS 10.13.
macOS 10.14 has changed the way USB ports are enumerated and named.
 

Which release of macOS?
