Raspberry Pi hits usenet

Violent streak makes up for its small size. Along with the usual comp.sys.acorn.* usenet groups read by many RISC OS users, another group that might be worth a look is a new group set up to focus on the credit card-sized Raspberry Pi. comp.sys.raspberry-pi went live on 2nd April, and is likely to carry more posts from users of operating systems such as Raspbian rather than RISC OS, though our favourite system has cropped up a small number of times in the month or so since the group was created.

32-bit sound software

Wave, Gen, you’re on RISCOSitory! A couple of old applications for generating RISC OS sounds have been updated for 32-bit compatibility by Jon Scott. The first of these, announced by Jon on the RISC OS Open forums as a re-release of a very old voice module generator, is Wavegen, an application that can create perodic sounds based on mathematical formula such as a simple sine or complex harmonic wavforms.

Cat_Draw 32-bitted

No, just because it’s on the internet and it’s called Cat_Draw, that doesn’t mean there are cute pictures of cats. Long time RISC OS user Martin Carradus popped up on the RISC OS Open forums in February in response to a comment about his application, Cat_Draw, not being 32-bit compatible. Martin initially offered to supply his source code, presumably to allow someone else to make the application 32-bit compatible, but a couple of hours later posted again to say that he had now recompiled it himself.

Wakefield 2013 show report

 A day at the races RISC OS event. It’s approaching the end of April 2013, and this year’s Wakefield Show has come and gone. This year’s show was the eighteenth, and was once again held at the Cedar Court Hotel, very close to junction 39 of the M1 – the same venue at which it has been held for the last few years, and where the show was originally held all those years ago. As usual, I was there to demonstrate and discuss my products, and also – in theory…

Programming the LPC1114

It’serial-ly useful thing. Dave Higton released LPC1114 at the beginning of February, with an update about a week and a half later, for use with a small piece of hardware with the same name – the LPC1114 being one of a family of devices [PDF] from NXP Semiconducters, all of which are ARM Cortex-M0 based and, due to their low cost and power requirements, are ideal for simple embedded applications. An example application for the LPC1114 device is given by Dave, who explains:
