SSH and RPi Raspbian Jessie PIXEL 25 nov 2016

It seems the SSH default acess in Raspbian has been switched off in the latets (25 nov 2016) release.

But easy to get it going by creating an empty file in the root of the SD card with name ssh (jut that, no extension, no content required)

* SSH disabled by default; can be enabled by creating a file with name “ssh” in boot partition

So another little step to perform when preparing a SD card for headless first boot!

Oh, the system nags about password after enabling SSH:

sudo apt-get remove -y pprompt for the gui prompt

The CLI warning is raspberrypi-sys-mods, delete the file /etc/profile.d/

Installing the Arduino 1.6.12 IDE on Raspberry Pi, with ESP8266 and RaspiDuino

Installing the Arduino 1.6.12 IDE on Raspberry Pi

1. Go to and download the Arduino IDE 1.6.12 for the ARM processor.
2. Open a terminal window.
3. Type cd ~/Downloads
4. Type tar -xvf arduino -1.6.12-*.tar.xz
5. Type sudo mv arduino-1.6.12 /opt
6. Type cd /opt/arduino-1.6.12/
7. Type chmod +x
8. Type ./

The new Arduino IDE will be in the drop down, along with your old Arduino IDE (probably 1.0.5 – which is installed when you type sudo apt-get arduino in a terminal window from the Raspberry). You will notice the difference immediately in the splash screen startup and the window pane header will read, “Arduino 1.6.12”.

ESP8622 with WiFi . If you are wanting to do this, navigate to File → Preferences and look near the bottom of the window that pops open for “Additional Boards Manager URL:”.

Type the following in the blank field: … index.json

and click OK.

Now, go to Tools → Board “<your last chosen board>” and click on “Boards Manager” at the top of the list.

Type “ESP8266” in the Filter Your Search box at the top of the window.

Esp8266 by ESP8266 Community will show up. Highlight it and click Install in the lower right corner.

Oberon version for the Raspberry Pi

(Found in the Oberon mailing list today!)

Josef Tampl has announced the availability of an Oberon version for the Raspberry Pi running 32-bit Raspbian.
You can download it from

This version of Oberon is based on ofront 1.4, an Oberon-2 to C translator.
It comes with a set of command line tools and an integrated version based
on the Oberon V4 system.
Oberon modules can be compiled and linked into shared object libraries(.so) and loaded and unloaded
from within the Oberon system.

A complete Oberon interface for the popular ‘Wiring’ library ( is included.
This library can be used for convenient access to the Raspberry’s I/O hardware.

You may also want to download manual pages, additional fonts, and platform independent Oberon V4 source and resource files.
The Ofront source files as well as a makefile are hosted on Github.


CP/M on the Pi! Ultibo baremetal app

EMUZ80 RPI is a CP/M emulator, by Ronald Daleske, for the Z80 processor the Raspberry PI (2). Here is the emulator without an operating system “bare metal” operated on the Raspberry PI. This particular application will start in about 5 Seconds.

This project shows, what is possible with the Lazaus/Free Pascal-Cross-Compiler from Ultibo.

The installation of Bare Metal programs on the Raspberry PI (2) is quite easy.
All you need is a blank SD card (or Micro-SD card for newer versions).
The SD card must formatted with the File System FAT or FAT32.
After then all files from the folder “boot” written directly to the SD card (inclusive the subfolders “CPM_LW_A” and “CPM_LW_B”).
