.Installing NetBeans For C++ Remote Development on A Raspberry Pi
THIS IS OUR PREFERRED WINDOWS DEVELOPMENT IDE FOR THE RASPBERRY PI The reason – you program on your nice fast Windows PC but under the bonnet it copies the files and uses the RPi to actually compile the project which, whilst a bit slower than using a high spec PC, solves all the issues of platform […]
Installing Eclipse On Raspberry Pi 2
Can you use Eclipse on the Raspberry Pi? On a Raspberry Pi 1 (pre RPi2 model B) Forget it! Technically eclipse will run, but not really! The RPi 1 is far too underpowered for it On a Raspberry Pi 2 Model B Yes we've got eclipse to run, but not with the cdt c++ compiler installed […]

RPi2 Model B IO Pins
Note that the schematic for the Raspberry Pi 2 Model B has not been released so we are unable to confirm if there are any changes to the specific signals used on the display and camera connectors. Changes Compared to Raspberry Pi 1 The Raspberry Pi 2 uses a new processor model so some pin additional […]

RPi2 Model B Hardware General Specifications
Official Raspberry Pi Page www.raspberrypi.org/products/raspberry-pi-2-model-b/ Core Differences To The Raspberry Pi 1 ARM V7 instead of ARM V6 processor architecture. (This opens it up to operating systems like Ubuntu, robot operating system, Windows 10, etc). Quad core instead of single core processor. For the operating system and multi threaded applications this provides a massive speed […]
UART control from PHP
Turning off the UART functioning as a serial console See the instructions here. Setup Permission You can determine the user PHP is running as with this command in a php page: <?php echo exec('whoami'); ?> It will typcially be 'www-data'. All serial connections, virtual or physical, are owned by the 'dialout' group so if you add www-data to the dialout group your […]
