MSP-EXP432E401Y: Configuration Help Needed for BOOSTXL-TECDRV Module with MSP432E401Y

---

### **Step 1: Install Energia IDE**
1. Visit the **Energia official website**: [Energia IDE](https://energia.nu/guide/).
2. Download the version suitable for your operating system (Windows, macOS, or Linux).
3. Follow the installation instructions to complete the installation.

---

### **Step 2: Open the `.ino` File**
1. Open the **Energia IDE**.
2. Click **File > Open**, navigate to the folder where the `BOOSTXL_TECDRV_LaunchPad_Source_v1_0_0.ino` file is located.
3. Select the file, and Energia will load it along with any dependent code modules.

---

### **Step 3: Configure Energia IDE**
1. **Select the target hardware**:
- Go to **Tools > Board > LaunchPad w/ MSP432 EMT (48MHz)** in the menu bar.
2. **Select the COM port**:
- Go to **Tools > Port** and choose the COM port corresponding to your MSP432 LaunchPad (typically assigned when the USB connection is made).

---

### **Step 4: Compile the Code**
1. Click the checkmark button () in the top-left corner to compile the code.
2. Wait for the compilation to complete, ensuring no errors occur. If errors appear, ensure all dependent files are in the same directory.

---

### **Step 5: Upload the Code**
1. Click the arrow button (→) in the top-left corner to upload the code to the MSP432 LaunchPad.
2. After the upload is complete, the LED indicator on the LaunchPad may blink, indicating the code is running.

---

### **Step 6: Verify GUI and Hardware Communication**
1. Attach the BOOSTXL-TECDRV to the MSP432 LaunchPad using the BoosterPack connectors.
2. Connect a 3.3V power supply to the BOOSTXL-TECDRV.
3. Open the TI-provided GUI, select the correct COM port, and click **Initialize TPS63810** to confirm the system is functioning.

**Description**:
I’m working on a temperature control project using the BOOSTXL-TECDRV module with the MSP432E401Y LaunchPad. I followed the instructions to install Energia IDE and download the provided `BOOSTXL_TECDRV_LaunchPad_Source_v1_0_0.ino` file. Here's what I’ve done so far:

1. Installed Energia IDE (v1.8.11E23) on Windows 10.
2. Set up the correct board: `LaunchPad w/ msp432e EMT (120MHz)`.
3. Selected the correct COM port.
4. Opened the `.ino` file in Energia IDE.
5. Attempted to compile the code.

However, during compilation, I encountered the following warnings and errors:
1. **Warnings**:
- `'typedef' was ignored in this declaration` (multiple instances for enums like `OPEN_LOOP`, `SENS_TYPE_I2C`).
- `ISO C++ says these are ambiguous` for `Wire.requestFrom()`.

2. **Errors**:
- `'strcasecmp' was not declared in this scope` (in the `aJSON.cpp` file).
- `'strdup' was not declared in this scope` (in the `aJSON.cpp` file).

Here’s part of the error output:

Error compiling for board LaunchPad w/ msp432e EMT (120MHz).

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

```

**Questions**:
1. Is there a specific fix for the `typedef` warnings, or is it safe to ignore them?
2. How do I resolve the `strcasecmp` and `strdup` errors in Energia, given that they appear in the `aJSON` library?
3. Should I replace `Wire.requestFrom()` with an explicit cast to resolve the ambiguity, and if so, what is the best practice?

Any advice or guidance on resolving these issues would be greatly appreciated!

Hi,

    Please refer to FAQ #5 about Energia support. https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/695568/faq-faqs-for-tm4c-arm-cortex-m4f-microcontrollers. We do not have Energia knowledge for MSP432E Microcontrollers and will not support questions using Energia on the E2E forums. Please direct Energia questions to the primary Energia forums at: https://forum.43oh.com/forum/119-energia/.
