Season's Greetings !

Only now once pause!
I wish all Merry Christmas and a happy New Year 2006.

small update of pC/OS provide

Due the porting to the first 32-bit processor necessarily became a first small update of the pC/OS Kernel.
Furthermore I inserted the past conditions of the AT91SAM7Sxx-Port using Keil. This does not run however so far stably. I still get at the most unbelievable Opcodes Undef_Handler-, PAbt_Handler- or DAbt_Handler- aborts.

AT91SAM7Sxx port of pC/OS ready

The port of the pC/OS Kernel on AT91SAM7Sxx is now finished.
As Toolchain the IAR Embedded Workbench was used. Sorry to Keil, with "...?T" and "...?A" it's not really possible to create a good port for ARM and Thumb mode.

lost line in the ATMega128-port of pC/OS fixed

What a bug...!
Normally I should check the sources, which I put on the server, again. If this precipitates, such a thing happens...
In the assembler file of the ATMega128-port on this server following line was missing:

_OSIntCtxSw:: ADIW R28,0x04 ; correct Y pointer for two calls ...

Thank's again to the bug reporter.

SAM7Sxx-DevMaster ready

Now the SAM7Sxx_DevMaster-Board is also ready.

SAM7Sxx_DevMaster -Board
SAM7Sxx_DevMaster -Board

Update to the Draft of the AT91SAM7Sxx_DevMaster

After some feedbacks now an update of the Drafts to the AT91SAM7Sxx_DevMaster-Board.

However I ask me, when the AT91SAM7S256, promised to the end of year 2004, it is finally to buy (individual samples is to give it)???

PS: At present also some ATMega128_DevMaster boards are still surplus. On interest simply send me a email.

Documentation for the ATMega128_DevMaster ready...

Finally, I have also the documentation ready for the ATMega128_DevMaster-Board...

Stress ...

Why begins the new year like the old one finished.. ?
Actually I want to revise the side shortly completely, but I come in such a way times again to nothing!
But, to avoid about confusions, I have from immediately all µC /.. Modules renamed in pC /.. like "pico-C".
Furthermore, I has deposite the current pC/OS Kernel with the ATMega128-Port once.

Here a small preview:

Project: new development board (with ATMega128)

  • Atmel AVR ATMega128 CPU (128kB Flash, 4kB RAM, 4kB EE-Memory)
  • 14.7456MHz (better bautrate timing as with 16MHz)
  • 32.768kHz Clock
  • 62kB ext. RAM
  • 2kB I/O-range (in 8 * 256Byte pages)
  • ISP and JTAG interface
  • RS232 interface
  • RESET-Generator plus manually
  • MMC/SD-Card Slot
  • "full" extended pinning
  • ATMega128_DevMaster -Board
    ATMega128_DevMaster -Board

    ATMega128_DevMaster -pinout
