Re: Stroboscopes: why smartphone LED can't blink fast?

That what you want as application (stroboscope) is not delivered is caused in part by the OS (though, for the application as flash light it's surely a bad idea to leave the timing to a standard non-real-time multitasking environment :P ), and in other part by the regulator hardware. Interesting you...

Re: Stroboscopes: why smartphone LED can't blink fast?

Other than debugging your own custom build of Android and writing your own high performance LED driver, I don't think there is an easy way to answer your query. Perhaps try the XDA developers forum.

But looks like your are using the wrong tool for the job, an Arduino solution would be more suited...

Re: Stroboscopes: why smartphone LED can't blink fast?

Expanding on this consider what would happen if you had multiple programs all trying to switch the led on and off rapidly running at the same time. What should the behaviour be? It makes sense for the OS to allocate a minimum time granularity for the LED especially taking into account possible hardw...

Re: Stroboscopes: why smartphone LED can't blink fast?

If you look at the stock driver source code for LED devices under Android, you can see at lines 65-80 that it tries to obtain an execution context and if not available schedules the work for some time later. As mentioned earlier, I would suggest this could be the reason for your issues rather than a...

Re: Stroboscopes: why smartphone LED can't blink fast?

Just guessing here but... I would imagine that flash is performed by an abstracted service in the phone OS and that this service runs on a scheduler and that this scheduler is servicing the requests too slowly. In fairness I doubt the designers of the OS had your use-case in mind and also increasing...

Re: c++

Will take a look when I get chance, but I would suggest that your syntactic clutter will increase along with your use of 'OO' '. I briefly used C in the 90s to implement objects under Microsoft's COM 'interface' based OO platform where C++ came as a welcome relief. [That book looks to be out of prin...

Re: c++

I never got on with the pseudo OO approach in C. I find the syntactic clutter difficult to read so just stick to shared state and functional decomposition. When in Rome...

Edit: Mike - note the correct usage of C :wink:

Re: Speech synthesiser cartridge

Vic- voder is very nice but too pricey considering that you can do the same job with a $2 Bluetooth chip and any android tablet or phone.

Re: WIP: Manic Miner port

Just asking for completeness sake, but any reason you haven't done a bit more with the title screen like the speccy version?

Would be easy to knock up with my screen designer for instance.
