Re: Rebooting Oxford Raspberry Jam

Is there a report anywhere on the previous event? How did it go? I'm hoping to attend, if work allows! I don't think anyone did a report, sadly. It went pretty well though for a new event, I can't remember offhand the exact numbers but there was a group of people there from the earlier incarnation ...

Re: Radio kits for your Pi

Announcing another new product, this time a 100mW transmitter board for your Pi. Licenced radio amateurs only I'm afraid. So far it's achieved 10MHz WSPR spots as far away as the USA, though this will get better as the radio propagation improves through the spring. http://shop.languagespy.com/collec...

Thanks! Though in fairness I should point out that I have yet to test that they work on a Pi 3.

Hardware base address on my shiny new Pi

Since I have just bought one from our friends at Pimoroni, I am guessing that all embargoes have expired and it is now OK to talk about the Pi 3. And I'm sure a lot of people will be doing just that. Could I make a request for an important bit of hardware info from anyone in the know at the Foundati...

Jessie killed my GertVGA! :)

I followed the install procedure on a freshly created Raspbian Jessie image on my Pi 2, no joy. Will dig into fault-finding tomorrow as it's late, but has anyone else got their GertVGA working on Jessie?

Absolutely. This script is a level removed from all that though, the clock code is in the C of freq_pi.

PiVFO, a variable frequency oscillator for the Pi

It's worth announcing here, I've written a Python script that provides a GUI for Jan Panteltje's freq_pi command line signal generator. It turns your Pi into a variable frequency RF oscillator using the GPCLK0 output on pin 7 of the expansion connector. https://github.com/JennyList/LanguageSpy/tree/...

Absolutely, and indeed it's exactly the same venue. It's all going down at Oxford Hackspace. But Code Club is a very different constituency to a Raspberry Jam. Even if there is some crossover between the attendees - and now the organisations. I for instance have very little interest in teaching kids...

I can already do that, that is produce a list of defined constants for each processor. I can even identify the processor, and select a base address accordingly. That's not a huge coding challenge. Already done it, as it happens. But the library I saw was specifically an abstraction library for ident...

Re: C library to detect processor type

I'm aware of those two, but yet again I'm not looking for a general purpose GPIO library.

The library I found was a Broadcom one, and its purpose was simply to abstract identification of Broadcom processors and return base addresses etc. Has anyone seen that one anywhere?

C library to detect processor type

Earlier this year I was porting some code from BCM2385 to BCM2386 and I did it the lazy way, changing hard-coded variables for peripheral base etc. At the time I found a Broadcom library that abstracted the process of getting these addresses, promising myself I'd come back and do it properly later. ...
