The Lab is based on the M16C/Tiny family of Starter Kits. These kits include SKP16C26A, SKP16C28 and SKP16C29-CL.3HEW4 M16C/Tiny Tutorial 127 July 2005The HEW / ICD Development ProcessThe HEW / ICD Development ProcessNC30 CompilerNC30 CompilerAbsolute file “.x30”Absolute file “.x30”Workspaceand Source windowsWorkspaceand Source windowsAS30 AssemblerAS30 AssemblerHEW Editor windowHEW Editor windowLN30 LinkerLN30 LinkerProject filesOptions and SettingsHEWBuild commandDebugSymbolsDebugSymbolsMachineCodeMachineCodeHEW DebuggerBuilder: Error reportingBuilder: Error reporting.r30files.c.h.a30.incCorrect ErrorsUART1RAMFlashMonitor FlashUser FlashMonitor RAMUser RAMM16C/Tiny MCU3.

As a debugging tool (during program debug), the ICD + HEW downloads a small kernel (or ROM Monitor) program with the user program to the M16C/Tiny SKP Board . This kernel provides a communication interface between the M16C/Tiny MCU and the ICD + HEW Debugger application on MCU status. While the kernel uses some resources of the M16C/Tiny, the operation of the ICD is transparent to the user’s program.As a programming tool, the ICD + Flash-over-USBTM(FoUSB) Programmer can be used to download user programs to the M16C/Tiny MCU on the SKP Board and many other Renesas’ flash MCU’s (the ICD will support other Renesas flash MCU’s by downloading an MCU Monitor Image (MMI) file for a particular MCU thru HEW or FoUSB Programmer).The ICD can be used with user’s target hardware providing the proper interface (details in RTA-FoUSB-MON manual, see www.renesas.com/skp ) NOTE: The kernel is only downloaded with the user program when Debugging but NOT when using the FoUSB Programmer.7HEW4 M16C/Tiny Tutorial 127 July 2005Development ToolsDevelopment ToolsHEW4An Integrated Development Environment (IDE) that invokes all necessary software for building your project.

After all the files in a project are compiled and assembled, a linker resolves the final address of the code within a single file. These steps can be tedious and repetitive. To make the process simple, we use an Integrated Development Environment (IDE) called HEW.9HEW4 M16C/Tiny Tutorial 127 July 2005Lab 2 Hands on SectionLab 2 Hands on SectionIn this lab you will:•Open and build a project in HEW•Launch a Debug session and:•download your program into the SKP hardware,•set breakpoints,•Step through your code, and•open various debug windows.•Edit a project file, re-build, download, and run the program10HEW4 M16C/Tiny Tutorial 127 July 2005Start HEWStart HEW1.
