Hi Scotty,
That looks like a great call - I'll check it out. I've installed it, and I'm going through the documentation, but it looks to be very close to what I need.
Thanks again,
Dave

OSMC control via Python
Hello all, I have a project that I'd like some help with. I'm trying to make a media centre that interfaces with some control hardware (could be buttons, could be something else - not relevant for this part of the conversation). What I need is to be able to get OSMC to automatically play a video/son...

Saving programs, and Internet connection
Hello, I've been having fun with the command-line Wolfram Language interpreter across a serial terminal (The graphical one is WAY too slow on my 1st gen. Pi). I have a couple of queries: 1) How do I save a session to a file, or write a program so I can run it later? 2) I can't get it to connect to t...

Hi Gert,
I noticed that Farnell are now advertising the Gertuino....but there's still no data on it! Can you spill the beans yet?

Bugblat PIF FPGA board
Has anyone seen this yet?
http://www.bugblat.com/products/pif/
Looks like an excellent step up from the Guzunty CPLD board, and is reasonably priced...although shipping is a bit of a drag to the UK.
Anyone tried one yet??? It's on my Christmas list!

Re: Controlling many lights individually
Something like this might come in handy: http://www.adafruit.com/products/1378 It seems that controlling LEDs is a common task. These chips require a stable clock source, so offloading some of the control to an Arduino might be a way forward, but you could still use to Pi to oversee the whole job an...

Re: Digital gauges
You'd do well to look into the OBD-II on-board diagnostics interface, and maybe consider looking at something like the "Torque" Android app for some pointers. If you want to do it with the Pi, I think there are some other OBD projects on the go at the moment - have a search around the foru...

Re: DIY RGB LED Controller *Help*
It looks like what you need is three PWM channels. Software-controlled PWM (Pulse-Width Modulation) would probably be fine for your application. Have a look through the forums and see if anyone's got three independent PWM channels running on a Pi already. If so, then all you'll need are three driver...

Re: CPLD Programming over GPIO
Hi Peter, I just spoke to Cypress, because I was surprised to see the PSoC5 discontinued... Good news! The PSoC 5 was an early release silicon with some de-rated features to get the part in to production for some lead customers. This has been replaced by the PSoC 5 LP. The specification of this part...

At the moment, it's all set up using their drag-and-drop gr...

Re: Calibration of temperature sensor
Well, at sea level melt-water from ice (that still has ice in it) is always at 0 degrees Celsius.
Alternatively, do what everyone else does and cross-calibrate with a thermometer you trust.

Hi - sounds like fun! You say you don't have a GuzuntyPi, but you've obviously heard of them, and what you're trying to do is almost exactly the same as what happens on the Guzunty. I suggest you read through all the documentation for that project (schematics, software tools etc..) until you underst...

Just thought I'd throw in my tuppence-worth. Trickle charging NiMHs is OK, but not really "supported" by the manufacturers. Having discussed it at length with some of the manufacturers, I can report that a charge current of C/30 will do no damage at all under most conditions. Therefore, if...

Quick additional query - when driving a clocked core, do I need to bridge JP11 so that GCK1 can get across?
If not, how do I clock it?
If so, how does gz_test work without this link??
Many thanks,
Dave
