Arduino Things

I just bought a Pimoroni RainbowHAT and am now waiting for it to arrive from the UK!

Here I found an excellent first getting acquainted with this platform: http://richardhayler.blogspot.nl/2016/12/getting-started-with-android-things-and.html

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 https://www.arduino.cc 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 install.sh
8. Type ./install.sh

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:

http://arduino.esp8266.com/stable/packa … 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.

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”).
