Re: GPIO precision timing (with minimal cost)

Use a microcontroller. A small Atmel AVR (e.g. Tiny2313) only costs 1-2$ and is up to the job, easy to program and provides a lot of flexibility. Thanks lb. I've had a bit of a dig around, looks like it could be a good option. I have had a playaround with an arduino as well so not totally charted t...

Re: GPIO precision timing (with minimal cost)

Add a digital FIFO chip to the GPIO output and enable GCLK and use the timer to give read pulses to the fifo chip, then take one bit from FIFO to drive your o/p. Cheap FIFO chips exist in many MHz speeds Thanks techpaul. Any specific chip number/specification you could recommend? Would it need any ...

GPIO precision timing (with minimal cost)

Having read these forums and other material I understand that (microsecond) precision timing for the GPIO is pretty much no go on linux because of its multi-tasking nature. I have a need to flash an led with microsecond precision (yes I’m emulating an IR remote control) so I’m guessing I need some f...

Re: Lego RCX/NXT robotic programming with Pi.

I've actually rewritten Anders mindstorms NXT bluetooth C++ library (and fixed a load of bugs, updated the code to include the newer colour sensor, added xbox 360 joypad support, and added the ability to write 24bit images). I'm very interested in this and will be even more so when it's up and runn...

Regardless of what the final 'additional' charges will be, sounds like they will be fair and reasonable. That's all one can ask for really, great stuff.
