Wondering how to get started with MSP430 launchpad and IAR embedded workbench at hand? Fear not for this video is intended to guide you!

This demo was produced on an ES449 evalutation boardfrom SoftBaugh (instructions are provided should you wish to use an alternative development board),using the IAR Embedded Workbench for MSP430 development toolsand a SoftBaugh FETP parallel port JTAG interface

The port and demo permit tasks to use the MSP430 low power modes 1 to 3.

IMPORTANT! Notes on using the IAR MSP430 RTOS port

Please read all the following points before using this RTOS port.See also the FAQ My application does not run, what could be wrong?

Source Code Organization

The FreeRTOS download contains the source code for all the FreeRTOS ports so contains many more files than required to run just this demo.See the Source Code Organization section for a description of thedownloaded files and information on creating a new project.

The IAR workspace used to build the MSP430 FreeRTOS demo is called RTOSDemo.eww and can be located in the Demo/msp430_IAR directory.

The Demo Application

Functionality

The ES449 prototyping board includes a built in LCD display and a single built in userLED. To make use of this hardware, the standard demo tasks that would normally flash an LED, instead flash ‘*’ characters on the LCD. The left most ‘*’ represents LED 0, thenext LED 1, etc.

The single on board LED is used by one of the ComTest tasks. It is toggled every time a character is received on theserial port.

The demo application creates 10 tasks – 9 of the standard demo application tasksand the idle task. When executing correctly the demo application will behave as follows:

  • The first three ‘*’ characters on the LCD are under control of the ‘flash’ tasks. Each will flash at a constant frequency, with the first ‘*’ being the slowest and the third being the fastest.
  • The on board LED will flash each time a character is received on the serial port (see the hardware setup section below).
  • Not all the tasks update the LCD so have no visible indication that they are operating correctly. Therefore a ‘Check’ task is created whose job it is to ensure that no errors have been detected in any of the other tasks.

    The ‘*’ in the fifth position on the LCD is under control of the ‘Check’ task. Every three seconds the ‘Check’ task examines all the tasks in the system to ensure they are executing without error. It then toggles ‘*’ 5. If ‘*’ 5 is toggling every three seconds then no errors have ever been detected. The toggle rate increasing to 500ms indicates that the ‘Check’ task has discovered at least one error.

Demo application hardware setup

The demo application includes tasks that send and receive characters over the serial port. The characters are transmitted by one task and received by another – if any character is missed or received out of sequence an error condition is flagged. Normally a loopback connector is required for this mechanism to work (so each character transmitted by the UART is also received by the UART). In this case the ‘loopback’ mode of the MSP430 UART is used and no external connector is required.

The demo application uses the LCD in place of LEDs so no other hardware setup is required.


Building

To build the demo application:
  1. Open the workspace file FreeRTOS/Demo/MSP430_IAR/RTOSDemo.eww from within the Embedded Workbench IDE.
  2. Select the required build (Debug or Release).

    Selecting the required build
  3. Select “Build Solution” from the CrossStudio project menu or simply press F7.


Downloading and executing

To download the application to the target hardware:
  1. Connect the FETP JTAG interface between the target and host. The target will be powered via the FETP JTAG interface and no other power source should be connected.
  2. Select “Connect MSP430 Flash Emulation Tool” from the CrossStudio Target menu.
  3. Select “Start Debugging” from the CrossStudio Debug menu. The MSP430 Flash will be automatically programmed with the demo application.
Once the application has been programmed into flash it can executed within the CrossStudio debugger. Alternatively, stop thedebugger (to power down the target), remove the FETP JTAG interface, then supply the target with an external powersource.

Configuration and Usage Details

Serial port driver

As provided the serial port drivers are configured for loopback mode. This enables the demo application to execute but switch loopback mode off for any other use.

It should also be noted that the serial drivers are written to test some of the real time kernel features – and they are notintended to represent an optimised solution.


RTOS port specific configuration

Configuration items specific to this port are contained in Demo/MSP430_CrossWorks/FreeRTOSConfig.h. The constants defined inthis file can be edited to suit your application. In particular – the definition configTICK_RATE_HZ is used to set the frequencyof the RTOS tick. The supplied value of 1000Hz is useful for testing the RTOS kernel functionality but is faster than most applicationsrequire. Lowering this value will improve efficiency.

Each port #defines ‘BaseType_t’ to equal the most efficient data type for that processor. This port definesBaseType_t to be of type short.

Note that vPortEndScheduler() has not been implemented.


To use a part other than an MSP430F449

The core real time kernel components should be portable across all MSP430F4xx devices – but the peripheral setup and memory requirements will require consideration. Items to consider:
  • prvSetupTimerInterrupt() in Source/portable/Rowley/MSP430F449/port.c configures the microcontroller timer to generate the RTOS tick.
  • Port, memory access and system clock configuration is performed by prvSetupHardware() within Demo/MSP430_CrossWorks/main.c.
  • The serial port drivers.
  • Register location definitions are provided by the file msp430x44x.h which is included at the top of Demo/MSP430_CrossWorks/FreeRTOSConfig.h.
  • RAM size – see Memory Allocation below.

Switching between the pre-emptive and co-operative RTOS kernels

Set the definition configUSE_PREEMPTION within Demo/MSP430_CrossWorks/FreeRTOSConfig.h to 1 to use pre-emption or 0 to useco-operative.


Compiler options

As with all the ports, it is essential that the correct compiler options are used. The best way to ensure this is to base yourapplication on the provided demo application project.


Memory allocation

Source/Portable/MemMang/heap_1.c is included in the MSP430 demo project to provide the memory allocation requiredby the real time kernel.Please refer to the Memory Management section of the API documentation for full information.

Interrupt Service Routines

Versions of FreeRTOS prior to V5.1.0 included two separate sets of port layer files for the MSP430:
  1. The officially supported version that uses the extensions provided by the Rowley compiler to implement interrupt service routines completely in C.
  2. A contributed port that required interrupt service routines to have assembly function wrappers.
FreeRTOS V5.1.0 only includes the officially supported version but introduces a pre-processor macro and a new header file that allows the users to define which method of writing interrupt service routines will be used. The following sections describe the steps required to use both methods. The UART driver within the supplied demo application also demonstrates both methods.

Method 1 only requires C code so is simpler to implement than method 2. It only saves and restores the task context when a context switch is actually required, so can also be more efficient. However – a context switch being performed within the interrupt will result in some processor registers being saved twice (once on interrupt entry, and then again for the context switch). This means the stack allocated to each task will need to be larger when using method 1 compared to that required when using method 2.

Writing ISRs – Method 1

To use method 1:
  1. Set the pre-processor macro configINTERRUPT_EXAMPLE_METHOD to 1. The supplied demo application defines configINTERRUPT_EXAMPLE_METHOD within FreeRTOSConfig.h.
  2. Use the __interrupt[ ] function qualifier to implement interrupt service routines within C files.
  3. If using low power modes – ensure __bic_SR_register_on_exit(SCG1 + SCG0 + OSCOFF + CPUOFF) is called prior to exiting the interrupt service routine.
  4. Use the standard taskYIELD() macro should a context switch be required from within the interrupt routine.

Writing ISRs – Method 2

To use method 2:
  1. Set the pre-processor macro configINTERRUPT_EXAMPLE_METHOD to 2. The supplied demo application defines configINTERRUPT_EXAMPLE_METHOD within FreeRTOSConfig.h.
  2. Provide an assembly function that will be installed as the interrupt handler routine. The required format of this function is demonstrated below. Note the assembly file must include the portasm.h header file to gain access to the required portSAVE_CONTEXT and portRESTORE_CONTEXT assembly macros.
  3. Provide a standard C function that is called by the assembly file wrapper to perform the actual interrupt handling work – again see below for an example.
  4. Use the portYIELD_FROM_ISR() macro should a context switch be required from within the interrupt routine.
WorkbenchBelow are examples of both the assembly file wrapper and C function portions of the interrupt implementation.
