Re: [Oberon] Export of Oberon Mail.SendCmd().

Generally, re-using code instead of copying is a good approach. If you do so, then the whole code of Mail is imported in News. Possible but perhaps there is even a better approach to re-use code. What about this: try to separate all common code in an own module (e.g call it Communication.Mod or MsgBase.Mod or Utilities.Mod or so) and import this new module in Mail and in News. br Jörg > Am 14.06.2023 um 19:53 schrieb peter(a)easthope.ca: > > Hello again, > > Several procedures in Mail are used in Oberon News.

In the current site are absent, but you can check the old copy on my github: https://github.com/pcayuela/Project-Oberon-2013-Wirth-Reed/blob/main/RISC-D… https://github.com/pcayuela/Project-Oberon-2013-Wirth-Reed/blob/main/RISC-D… There are the pictures.

Here (http://www.projectoberon.net/txt/FAQ.txt) it says that a daughter board is detailed in the site www.projectoberon.net: ... The reference implementation was developed on a Digilent Spartan 3 Board containing a Xilinx XC3S200 FPGA, 1MB static RAM memory, VGA display interface, RS232 serial and PS/2 keyboard:http://store.digilentinc.com/spartan-3-board-retired/ A simple daughterboard (construction details described on http://www.projectoberon.com) added a PS/2 mouse interface, an SD-Card for a filesystem, and a simple Nordic nRF24L01-based wireless network. ...

The author of the "Oberon RTK framework" referenced via the forum link introduces it as: "Oberon RTK is a framework to support writing control programs in Oberon for the RP2040 Cortex-M0+ microcontroller using the Astrobe for Cortex-M0 cross-compiling IDE. RTK stands for “real-time kernel”, that is, an embedded multi-threading kernel to allow to divide, and program, the controller program as set of separate control processes." For more information see: https://oberon-rtk.org/ Maybe Oberon RTK merits a separate heading somewhere between an Embedded System and a Personal Workstation? 2. Our support for the Project Oberon Workstation is detailed here: https://www.astrobe.com/RISC5/Workstation.htm This also is somewhat of a hybrid system. It describes our implementation of the standalone Project Oberon workstation running on actual FPGA hardware rather than an emulator. However, because it is source and object file-compatible, the Astrobe for RISC5 compiler can also be used as a cross-compiler to develop and compile on Windows and then upload the resulting object files to be executed on the workstation. Apologies if my replies raise more questions than answers ;-) Regards, Chris Burrows CFB Software https://www.astrobe.com

Is this the smallest Oberon (program) platform to date?
by Chris Burrows 22 Feb '24

Twelve years ago I asked the question "Is this the smallest Oberon (program) platform to date?" https://lists.inf.ethz.ch/pipermail/oberon/2012/006407.html This has since been well and truly beaten! We have now used Astrobe for Cortex-M0 to target a WaveShare RP2040 Zero board which includes features such as: * Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz * 264KB of SRAM, and 2MB of on-board Flash memory etc. etc. The board measures just 1.8cm x 2.35 cm and is priced at $US 4. For more details see: https://www.waveshare.com/product/raspberry-pi/boards-kits/rp2040-zero.htm?… The source code that we used to do this was developed by one of our Astrobe users. He has published an impressive set of libraries, tools and examples for the Raspberry Pi Zero and announced their availability here: https://www.astrobe.com/forum/viewtopic.php?f=9&t=776 You can request a free copy of the latest Personal Edition of Astrobe for Cortex-M0 to compile this code from here: https://www.astrobe.com/personal.htm -- Regards, Chris Burrows CFB Software https://www.astrobe.com
