The Pi Has Landed

It arrived. After quite some delay my Model B Raspberry Pi has arrived.

The Raspberry Pi is powered by the Broadcom BCM2835 SoC which includes an ARM1176JZF-S core running at 700Mhz, 256MB SDRAM and a Videocore 4 GPU which is capable of BluRay quality playback (H.264/MPEG-4 AVC at 40MBits/s) which puts it roughly on par with a 1st generation Xbox with slightly better graphics.

There are two models of Pi. The Model B which is ‘available’ at […]

It’s a common situation in software development: you’ve acquired a class – either from a third-party source, or inherited from another project – that’s got some really useful features, but its interface doesn’t quite meet your immediate needs. Two typical scenarios are:

The interface is too big; you just want your clients to have a small subset of the facilities on offer.
The interface signatures don’t match what your client code needs (and you don’t want to – […]

I have finally finished and sent off my presentation for next weeks Hitex one-day ARM User Conferences titled “ARM – the new standard across the board?” at the National Motorcycle Museum in Solihull.

Back in February, at the embeddedworld exhibition and conference in Nuremberg, Germany, ARM announced the latest version (version 3) of the Cortex(tm) Microcontroller Software Interface Standard (CMSIS). The major addition is the introduction of an abstraction layer for Real-Time Operating Systems (RTOS).

The presentation I’m giving explains; what […]
