wanted: robotics multi-IO shield, 8 motors, lot of IOs

I'm looking for a robotics multi-IO shield providing plugs for external L298 H bridges (or even more powerful ones which I already have, on proprietary backpanes) - to control 8 motors feat. rotary encoders - plus extra digital (at least extra 16x) and analog pins (ADC 10-bit, at least 10x) - plus a...

Re: a noob's question: use an external USB HD for data save/

yes, I found it!

media/pi/[drvname]

the rest I didn't understand, but now that it's automatically listed I can save some SD card program files to my USB drive

excellent, thanks a lot!

Re: a noob's question: use an external USB HD for data save/

so the mount thing was rubbish?

- yes, Im running the GUI.

I already tried to just plug my USB drive to the Pi but I couldn't find a USB drive listed, so what's wrong? where should it be, how is it named?

Re: a noob's question: use an external USB HD for data save/

as I'm completely new to Linux:

just plug it to either Pi USB port

then enter on LX terminal
sudo mount /dev/sda1 /mount/point

exactly this way - that's it?

Re: Reading GPIO input triggered by IRQ

ok, but even if I'll do so then the calculating encoder update task will be faulty when the moment when it's been triggered is not regularly within quite/rather exactly always each 100µs. Finally, what would exactly updated pin states help, if the processing of it's values is shaky and jittering? Wh...

Re: C/C++ crosscompiler on a Windows PC ?

netbeans is for Linux, isn't it?

- edit now I found it... also for Windows and almost as huge as Eclipse, but unfortunately also the Java SDK is needed which is one thing that I really hate to have on my PC.

No really simple IDE like Geany out there?

At least it must be as simple as Geany : just 1 editor screen, 1 compiler message screen, 1 menu for compiler and m...

Re: Reading GPIO input triggered by IRQ

yes, that's clear, but the pin-polling and encoder-calculating function is not running in the main task allone, but it has to run in a parallel task "in the background". So even if the GPIOs are polled quickly - for encoder updating the pin readings have to be repeatedly re-calculated in a update-En...

Re: Reading GPIO input triggered by IRQ

thank you very much for this link! Nevertheless, I don't see how you're doing the pinchang-e or timer-interrupt thing? gpioDelay(20000); /* check pos 50 times per second */ so for 10,000 times p.sec. it should be gpioDelay(100); /* check pos each 100µs safely ?? */ To run this in an extra pthread ta...

Re: C/C++ crosscompiler on a Windows PC ?

I'm using just what is already installed of gpp on Raspbian,
and on my PC I'm using what is installed by the Arduino IDE (gnu C/C++ crosscompiler for AVR and ARM), there surly must be something, but nothing additional or specific - what are toolchains actually? Are you experienced in using them?

Sorry, I didn't understand that the problem is caused by a (missing) video accelerator or a graphics card. I assumed it was rather a USB driver issue.. can you recommend an external video accelerator, e.g. by USB, providing also HDMI output like the built-in one? Working out of the box with the Rasp...

hey, which crosscompiler can I use for my Raspi on a Windows PC ? FTM I'm using Geany, compiling on-board the Raspi, but that's excruciatingly slow.

(100µs for timer IRQs should fit actually, for pinchange interrupts perhaps quicker)
