Introductio n This manual is designed to answer, in tutorial form, the most common questions asked about using the Renesas Starter Kit: The t utorials help explain the following: • How do I compile, link, download, and run a simple program on the Renesas Starter Kit? • How do I build an embedded application? • How do I use Renesas?[...]

Chapter 3. T utorial Project Wo rkspace The workspace includes all of the files for two build conf igurat ions. The tutorial code is common to b oth the Debug and the Rel eas e bui ld configurations. The tutorial is desi gned to show how code can be w ritten, debugged then downloaded in a ‘Debug’ situatio n. The build configuration menu in High[...]

Chapter 4. Project W orkspace 4.1. Introduction High-performance Embedded Workshop is an integrated development tool that allows the user to write, compile, program and deb ug a software project on any of the Renesas Microcontrollers. High-performance Embedded Workshop will have been in stalled during the installation of the software support for th[...]

The next dialog presents the three types of example project available: 1. Tutorial: This is the one of interest at this time; the code is explained later in this manual. 2. Sample code: this provides examples for using various peripherals . If you select th is and c lick < Next> it will open a new d ialo g allowing the selection of many code [...]

Chapter 5. Building the T utorial 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 s hould be the first option on the drop down menu. The dialog that is displayed will b e specific to the tool-chain select[...]

5.2. Connecting the debugger For this tutorial it is not necessary to provide an external power sup ply to the board. The power will be obtained from the USB port. Pl ease be aware that if you have too many devices connected to your US B port it may be shut down by Wi ndows. If this happens remove so me devices and try again. Alternatively provi de[...]

• The Flash Memory write pro gram will be downloaded to the target. • The Output window in High-performance Embedded Workshop will sho w ‘ Connected’. Note: The connection to the target will activate the debugger buttons on the High-performance Embedded Workshop toolbar. Now is a good time to save the High-performance Embedded Workshop sess[...]

Chapter 6. Downloadi ng and Runnin g the T utorial Once the code has been built in High-performance Embedded Workshop it needs to be downloaded to the Renesas Starter Kit itself. There will now be an additional category in t he workspace view for ‘Download Modules’ • Right click on the download module listed and select ‘Download’. Note: T[...]

• Place a breakpoint at the call to InitialiseDisplay subroutine. Breakpoints can only be set when the E8a is connected to the tar get and the module is downloaded. Br eak po int s can b e set by double-clicking in the grey column containing the PC arrow next to the line to break at; or s electing the line and pressing F9; or right click on the l[...]

The code will execute to the selected line and stop. An automatic breakpoint was inserted in the code and then removed after ca lling the break. • Press ‘Step Over’ on the debug toolbar. The code will run and flash the LEDs 200 times. The debugger w ill not exit until all 200 flashes ha ve completed or a button is pressed on the Renesas Start[...]

• Press ‘CTRL-B’ to open the breakpoint window. This dialog is not available if user debugged using eventpoints as suggested at top of page 10. ‘CTRL-E’ will open the eventpoint window. Eventpoints can be viewed in Breakcondition tab of event window. • Press <Remove All>. • Press <OK> . • Open the file ‘main.a74’ •[...]

The dialog will close and a new pane will open in the work space containing the variable. • Press <Go To Memory> In the ASCII column on a Memory Window, it is possib le to see th at the string has been successfully initialised to ‘ STATIC ‘ . • Set a breakpoint on the call to DisplayString subroutine inside the for loop. • Press ‘[...]

Chapter 7. Project File s 7.1. Standard Project Files Each of the tutorial files has detailed comment text describi ng the function of each code entry. Please refer to the source cod e for greater detail on the purpose and operation of the assembler specific details. 7.1.1. Mai n tutorial code (mai n.a74 / mai n.inc) This is the entry point of the [...]

7.1.2. Board i niti alisation code (hw setup.a7 4) There are two stages to the configuration of the microcontroller device. The code to demonstrate this is therefore split into t wo functio ns. Each function is written specifically for the dev ice supported. The function calls are shown be low. 15[...]
