  • Page 7: Chapter 3. Tutorial Project Workspace

    Chapter 3. Tutorial Project Workspace The workspace includes all of the files for two build configurations. The tutorial code is common to both the ‘Debug’ and the ‘Release’ build configurations. The tutorial is designed to show how code can be written, debugged and then downloaded without the debug monitor in a ‘Release’...

  • Page 8: Chapter 4. Project Workspace

    4.1. Introduction HEW is an integrated development tool that allows the user to write, compile, program and debug a software project on any of the Renesas Microcontrollers. HEW will have been installed during the installation of the software support for the RSK product. This manual will describe the stages required to create and debug the supplied tutorial code.

  • Page 9: Build Configurations And Debug Sessions

    The next dialog presents the example projects available. Choose the tutorial code which will be explained later in this manual. There is also an option for sample code which provides examples for using various peripherals. This will open a new dialog allowing the selection of many code examples for the peripheral modules on the device.

  • Page 10: Chapter 5. Building The Tutorial Project

    Chapter 5. Building the Tutorial Project The tutorial project build settings have been pre-configured in the tool-chain options. To view the tool chain options select the ‘Build’ Menu item and the relevant tool chain. This should be the first option on the drop down menu. The dialog that is displayed will be specific to the tool chain selected.

  • Page 11: Connecting The Debugger

    5.2. Connecting the debugger For this tutorial, it is necessary for you to power the RSK2+ from the supplied PSU, as the E10A debugger cannot supply power to the RSK. The E10A debugger will be powered via the USB cable. Please be aware that if you have too many devices connected to your USB port, it may be shut down by Windows.
  • Page 12 Press the ‘RST’ button on the RSK2+ board. • Click <OK> • Please wait until the message “Connected” • appears in the ‘HEW output’ window – this indicates that the RSK2+ board has successfully connected. Click ‘Emulator System’ icon on the tool bar. •...

  • Page 13: Chapter 6. Downloading And Running The Tutorial

    Chapter 6. Downloading and Running the Tutorial Once the code has been built in HEW it needs to be downloaded to the RSK2+. There will now be an additional category in the workspace view for ‘Download Modules’ Right click on the download module •...
  • Page 14 Maximum eleven eventpoints can be set. Eventpoints do not require programming the flash memory, and thus are faster to use. Please refer to the following document for further information: SuperH™ Family E10A-USB Emulator Additional Document for User’s Manual Supplementary Information on Using SH7269 and SH7262. Press ‘Go’ on the Debug Toolbar. •...
  • Page 15 The code window will open ‘main.c’ and show the new position of the program counter. Support for the IIC channel 2 devices has been included in the tutorial code. We do not need to be concerned about the details of the IIC interface except that the interface has been written to support this sample board so the connected devices (port expanders, Audio codec, HDMI device and touch screen controller can be accessed safely by the user code.
  • Page 16 Right click on the ‘FlashLEDs(); function and select • ‘Go to cursor’. The code will execute to the selected line and stop. Press ‘Step Over’ on the Debug Toolbar. • The code will run and flash the LED0, LED1, LED2 and LED3 for 200 times. The debugger will not exit until all 200 flashes have completed or a switch is pressed on the RSK2+.
  • Page 17 The modified string is also displayed on the LCD There are several versions of the timer function depending upon the peripherals available in the device. The default function is TimerADC which we shall demonstrate here. The ‘TimerADC’ function initialises an interrupt on an available internal timer. On a compare match in the timer module, an interrupt is generated.

  • Page 18: Chapter 7. Project Files

    Chapter 7. Project Files 7.1. Standard Project Files The RSK tutorials are configured so that it is possible to provide the same tutorial code on multiple RSK products. This allows the evaluation of the different processor cores using equivalent code. To achieve this, the following files are common between all device cores and tool chains.
  • Page 19 The call to ‘HardwareSetup()’ configures the external bus interface to access external memory and initialises device hardware and peripherals before they are accessed by the tutorial software. The cache memory has been configured for release build only in write-back mode. After initialisation the ‘main’...

  • Page 20: External Bus And Memory Configuration (Bus-Init.c/Bus-Init.h)

    7.1.2. External bus and Memory configuration (bus-init.c/bus-init.h) External bus initialization and cache memory configuration has been implemented in this function. The tutorial project initializes NOR flash only.

  • Page 21: Board Initialisation Code (Hwsetup.c / Hwsetup.h)

    7.1.3. Board initialisation code (hwsetup.c / hwsetup.h) Further hardware initialisation should be performed in this function. For debug purposes, the interrupt priority registers are initialised to zero (as they would be after a power on reset). In the case of the tutorial, the interrupts are configured and the LCD interface is initialised.

  • Page 22: Main Tutorial Code (Main.c / Main.h)

    The display initialisation and string display functions operate on the LCD display module. In addition to the tutorial code several samples of use of the on chip peripherals are supplied. Check compatibility with a ks0066u controller and pin connection on the schematic before connecting an LCD module not supplied by Renesas.
