Re: I've been made redundant

I'm technical - IT and Engineering manager - and a fairly handy DIY-er (hand built a couple of extensions at home for example). A while back I was talking to my mate, a property developer, and I mentioned that if I ever lost my job at [major multinational] I'd quite fancy doing block paving for a li...

Re: Wanted: TurboMMC adapter with MMFS2 ROM

I do a printer-port adapter for an SD card which works with MMFS2 - details here: https://stardot.org.uk/forums/viewtopic.php?f=8&t=20843&start=60#p298665 It's not "turbo" but honestly, the difference loading Tricky's Menu from a turbo or non-turbo unit is about 2s which is fast en...

Re: Export Beeb MMC Corruption

e668ecp's issue was different from Rhubarb's - his was a problem with his Watford sideways RAM board, and switching to the non-SWR version of P/MMFS worked for him. Rhubarb's issue - well, not sure...half working but giving a corrupt directory listing sounds most likely a low or intermittent voltage...

Re: BBC-FDC floppy controller for Raspberry Pi - New Batch In

Yes, still available. I've got loads of PCBs in, and have just ordered the chips I need to build up another 5 - depends on christmas post of course, but I should be able to get them out in the first week of January for the 3 people who've requested them. Once I've got boards built and tested, I'll l...

Please could you explain your set up in a little more detail:

Re: BBC-FDC floppy controller for Raspberry Pi - New Batch In

No problem guys - I've got the boards in for about another 15 or so, but only the buffer chips for one.

I'll get some more chips on order and get boards out to you shortly after - not sure what RS Components' deliveries will be like, so might be early in the new year.

Re: Any Python programmers here willing to chat through stuff?

Ahh ok, makes sense. Coding on the Pi 3 has been fine in Raspbian - Python works really well in the Thonny IDE. Only reason not to on the Pi Zero is that it crawls while trying to do anything in the DE - might try it in a really minimal openbox DE and see if that's usable. As I learn, it's helpful t...

Re: Any Python programmers here willing to chat through stuff?

So, the code is all running nicely on a Pi Zero, driving the matrix board. Apart from the fact that the Pi Zero doesn't have a real time clock (who knew!), it's doing just what I need. I've got into using Thonny IDE because it allows me to step through and debug - but with the Pi Zero it's easier to...

One more tip... a regular timer event will put less load on the cpu than an infinite loop.
Just out of interest - if I kept my infinite loop but put in a 0.5s wait, would that have the same effect, or does a wait hammer the CPU as well?

Re: Any Python programmers here willing to chat through stuff?

So, the thing I'm doing right now is driving an LED Matrix over SPI from a Raspberry Pi.

I've got the hardware working, and the code I've hacked together actually works just fine - I really just want some pointers on making it all more efficient. I'll post the code shortly - thanks!
