RX showing great potential in RX

Posted by ckgrier Jan 29, 2010

For a product we're not really promoting much... the RX chips seem to be gaining a lot of good press.

In order to run M16C Renesas drivers on windows 7 64-bit you can fo the following:

 

1) Go to: http://www.microsoft.com/windows/virtual-pc/download.aspx and follow the instructions on how to setup Windows Virtual PC with windows XP.

 

(The user will have to download a 500mb file, and another virtual pc file installation file.)

 

2) Load the M16C Renesas drivers inside the virtual PC:

 

Once you have XP running use the flash development kit to install USB Renesas E driver then made windows manually look for the driver within Device Manager.

 

Note: The Renesas board would not be picked up within the Windows 7 device manager, but I was successful in the virtual desktop
of Windows XP. The virtual desktop is windowed or maximized onto the Windows 7 desktop and all HEW processes and compiling worked without a problem.

 

Note2: This should work for 32-bit version but hasnt been tested.

 

Note3: Thanks to Christopher DeLeon for these instructions!

The eCos operating system is a lightweight open-source OS that leverages the tools developed for Linux, but doesn’t require the code space or CPU performance that larger Operating Systems require. Details are here . It is mostly used for Ethernet connectivity in small embedded applications.

Uwe Kindler of cetoni GmbH +has developed a port of +eCos to H8S microcontroller architecture. The port includes various variant and platform ports (i.e. for EDOSK2674) and a number of drivers (i.e. Serial, Network, RTC...). cetoni also hosts a prebuild h8300-elf toolchain for eCos (Cygwin only) and a detailed + +porting guide for H8S variant and platform ports.

This is not Renesas endorsed or funded, as far as I know. Older versions of ECos for the 2674R EDOSK boards have been around for at least two years, but they were not as well documented as this version, and didn’t contain a porting guide.



An interesting note is that Uwe ran Dhrystone 2.1 Benchmarks on his eCos system and got 2.4 VAX MIPS rating for our chip running at 33mhz (with external RAM and FLASH.) This is considerable lower than we’d expect on that MCU – but factors like the GNU compiler performance and external memory may explain the low number.

R8C and M16C Development boards in Info

Posted by gpatsil Jul 14, 2009

From Mikrocontroller in Germany. They've got their own development boards with LCD modules and DIP adapters.

R8C and M16C Development boards

 

Check out this web link to what looks like a University project. There's an M16C running graphics on a small monochrome module. They also have an R8C solution.

These boards don't seem to have debugger connections. You'll also note that they appear to be designed for hand-assembly.

This is related to a previous "info" item http://www.renesasrulz.com/community/info/blog/2009/07/14/schematic-and-dip-package-adapter-for-the-r8c13

Web link to the boards: http://www.mikrocontroller.com/eng/R8C13-ctrl.php

On the Eagle CAD website Glyn - Elektor uploaded a Schematic and DIP package adapter for the R8C/13.

Schematic and DIP package adapter for the R8C/13

RC8 Adapter

It was uploaded in May here:

 

 

Good news is it can be used as a starting point for other R8C layouts with this CAD package.

Work from anywhere in Info

Posted by gpatsil Jul 14, 2009

www.RenesasInteractive.com houses nearly 2 dozen VirtuaLabs. Real hardware and software for you to use, and it's free.

Work from anywhere.

 

At www.RenesasInteractive.com, you can sign up for free. This website runs 24/7 and can really help to learn and use Renesas MCUs.

 

1- RenesasInteractive has tons of flash based training courses that you can take. These self paced courses give you the tech details of a wide range of Renesas MCUs. At the end, you can take a short quiz to become RenesasInteractive certified.

 

2- VirtuaLabs. VirtuaLabs are REAL hardware and software setups sitting in a giant server rack. Using a VirtuaLab, you can take control of these tools just like they are sitting on your desk. This is a GREAT way to try before you buy. The Renesas VirtuaLabs contain different hardware setups from small dev kits to full blow in system emulators. That's right, try out a $5,000 emulator setup for FREE!!!!

The coolest story we've ever heard was from a person working on a small robot design. They just could not get a serial protocol debugged with the tools they had. The went to www.RenesasInteractive.com, uploaded their code into a VirtuaLab that had an emulator, and in 15 minutes had their code working. How's that for free!?!

Micrium, a leading provider of high quality embedded software components, today introduced an upgraded version of their award winning uC/Probe, a unique new tool for embedded developers to monitor all their embedded systems design in a live environment.

Micrium Releases HEW TargetServer Compatible uC/Probe RTOS Support

 

By providing simulation on a Windows platform users can test a good portion of their embedded software and be able to visualize it using uC/Probe.  Another advantage for users is that visualization screens can be created offline and thus be ready when the actual hardware shows up. The new features considerably strengthen uC/Probe’s capabilities as a demonstration and marketing tool, as it can now demo new products without needing to have hardware connected to the PC.

Renesas now has some fairly complete reference designs based around the M16C/26A RSK development boards. Download the software and check them out! This code will port to larger M16C devices.

Renesas RSK Development Kit "Application Page"

 

These applications are designed to highlight features of the M16C MCUs.

  • The application programs are written in the C language.
  • For more details of the MCU's function, please see the hardware manual.
  • More detailed explanation is available for each program. Click the title of each application program to see it.
  • The ZIP file of the application program stores the full set of necessary program.
  • Adobe Acrobat after ver. 4.0 is necessary to see PDF of the application notes.

    The H8S/2378 MCU with on-chip Flash and DMA peripherals are being used to drive small TFT displays. What makes this remarkable is the ability to drive the display from an external SRAM frame buffer, without significant glue logic from a 16/32 bit MCU - while leaving the CPU free to do other tasks.

    WhiteBream.com is selling the E105 Evaluation board with Stack and IrOBEX, IRCOMM, IrLPT. The development tools allow you to create your own code in HEW and the Whitebream libraries to connect to another IrDA device.

    IrDA Evaluation Board - with H8/Tiny

     

    http://www.whitebream.com/e105.shtml

     

    This board has an FPGA on it, but the same stack could easily port to an H8 (or M16C for that matter) that had on-chip IrDA PHY layer support - like the 38076.
