Add the RTD Drivers to S32DS

Select downloaded SW32K3_S32M27x_RTD_R21-11_4.0.0_D2311_DS_updatesite.zip file (shorter one from the file names).

Note: Do not add RTD 4.0.0 P20 file now! If RTD 4.0.0 P20 is added, the RTD 4.0.0 will not appear in in the list. If this happen, you may click on Manage Sites link and delete the RTD 4.0.0 P20 file location from the list.

2.6 Install the RTD Drivers

Install the RTD 4.0.0 from the list. Be aware that RTD 4.0.0 may appear on the list more than twice. Ensure that you selected the version that supports only/also S32M27x (See content of the Overview window on the right side).

2.7 Add the RTD Patch 20 to S32DS

Repeat the installation steps 2.5 and 2.6 also for patch P20 (the longer one from the file names) SW32K3_S32M27x_RTD_4.4_4.0.0_P20_D2403_DS_updatesite.zip file.

Again, ensure that you selected the version that supports only/also S32M27x.

2.8 Get FreeMASTER Application Tool

Download and install FreeMASTER application tool for real-time debugging.

Tip: For this training you may even skip the Lite service installation (for which the activation code is required).

2.9 Get AMMCLib for S32M27X

Download and install AMMCLib for S32M27X.

Tip: If possible, install AMMCLib in their default path location for later easy path modification.

2.10 Get the S32M276 Motor Control Application

Download and install the S32M276 motor control application software.

Note: The application checks version and whether appropriate AMMCLib was correctly installed or not. If not (red note), install AMMCLib and reinstall the S32M276 motor control application software. That will simplify the next project import (paths to the latest AMMCLib will be already updated).

The recommended accessory kit for S32M276SFFRD board is BLDC_KIT (software developed and tuned for given motor), however you may use any suitable 3 ph motor and 12 V power supply instead.

BLDC Motor Control Accessory Kit with Cables Top View

BLDC Motor Control Accessory Kit with Cables Top View

BLDC_KIT Content:

• 95 W BLDC motor with HALL sensors Sunrise 42BLY3A78-24110
• Plexiglass
• 12 V, 5 A power supply Meanwell GST60A12-P1J
• Power supply cable with set of universal plugs
• 4 self-adhesive standoffs for any EVB Takachi AST3-10B
• Micro-USB cable

In addition to BLDC_KIT, you will also need:

• Standard 6.3 mm FASTON connectors (3 pcs for motor, 2 pcs for power supply)
• Wire conversion from 2.1 mm barrel connector (male) to FASTON
• UART-USB serial interface for run-time debugging
• JTAG debug interface like PEmicro USB Multilink or Segger J-Link

Let's take your S32M276SFFRD motor control kit for a test drive.

4.1 Select Application and MCU Programming

Select the appropriate PMSM or BLDC motor control application from the installed directory.

To import the installed application software project in the S32 Design Studio IDE for S32 Platform:

1. Launch S32DS for S32 Platform
2. Go to File → Import, then select General → Existing Projects into Workspace
3. Navigate to the installed application directory: NXP\MC_DevKits\S32M276SFFR\sw and choose appropriate project and click OK. Then, click Finish

   Note: Check the box for the option Copy projects into workspace.

   

4.2 Use Configuration Tool

1. Unfold structure of the project with low-level drivers and double-click on *.mex file to open the project configuration in S32 Configuration Tool
2. Please ensure that you configure appropriate project and click on "Update Code" button for generating configuration files

4.3 Upload Software and Debug

In S32DS, return back to the C/C++ perspective.

Use the Debug Configuration menu and select the predefined debug configuration for building and uploading software into MCU.

Upload Software and Debug

Upload Software and Debug

The S32DS will switch into debug perspective where you may let the code run by clicking on Resume (or press F8), and use Disconnect to avoid interference between the S32DS IDE debugger and the FreeMASTER tool.

4.4 Set Up the Debugging Tool

Launch the FreeMASTER application.

To open the *.pmpx FreeMASTER project <selected project>\FreeMASTER_control, click File → Open Project .

Note: You can also start it by double clicking directly in the S32DS project folder.

To enable communication, in the FreeMASTER tool bar, click Go (or press Ctrl + G).

Successful communication displays in the status bar at the bottom as: RS-232 UART Communication;COMn;speed = 115200

Motor Parameters (Optional Step)

If you do not use BLDC_KIT (motor Sunrise 42BLY3A78-24110), you may need to edit the motor parameters according to used BLDC/PMSM motor. In the Motor Control Application Tuning (MCAT) Tool switch to Parameters tab and edit values on left side.

Once you finish, click on Store Data, switch to Output File tab and Generate static configuration file.

Now repeat step 4.3 to build the project and upload the code into MCU.

Note: MCU will go to reset, FreeMASTER reconnecting might be need (Ctrl + K, Ctrl + G).

Spin the Motor

Click the App Control tab on the Motor Control Application Tuning (MCAT) Tool menu to display the application control page.

Configure the motor rpms and turn on the motor drive.

Check Pending Faults

In case of pending faults, click the Clear FAULT on the FreeMASTER MCAT control page.

Start Application

Click On/Off on the control page to initiate clockwise/counterclockwise spinning of the rotor.

Set Speed

Change the speed required variable to set the speed. Go to the Variable Watch window and modify Speed Required variable or click on the speed gauge.

Stop application

Stop the application by clicking On/Off button on the FreeMASTER MCAT control page.
