problems with buttons

to start with i thought this was a problem with the pi but ive tried another one since and its the same. just trying to do a simple button press to print message script, but when i run it its backwards, it constantly thinks the button is being pressed unless you hold it down. is this normal or is so...

Re: simple adventure game.

to be honest half of what youve posted is basically greek to me at the moment, as i said it was never meant to be anything serious just something to to do with the basic commands id learned already to help me remember them a bit better. the end result was what i wanted, it made me repeat what id lea...

Re: simple adventure game.

i too decided after reading through "byte of python" and a few other books that id make a simple text adventure, it was very easy to make a simple 3X3 grid of rooms and make a basic get yourself out type of game. since then i found that rather easy and quite cool (took me right back to my zx81 days!...

Re: can someone please help debug my simple py prog?

yeah that part is long gone now, calling main in the blink functions was just an attempt to get it to return me to the main prompt again, i now have it working with threads, i just need to find out how to kill them once the next is called as even when i ended the program the LEDs were still blinking...

Re: can someone please help debug my simple py prog?

thanks for your advice, i asked on the python irc and they suggested the same thing or using event looping or blocking io, good job its a bank holiday as ive got a lot of reading to do @tim thanks for the tip, that was actually mainly because i was messing around with it to see if i could get it to ...

can someone please help debug my simple py prog?

im trying to create a basic number guessing game which flashes an LED via GPIO with the LED flashing faster the closer you are to the number (its for teaching to others but im not that experienced myself, its a bit of one of them "i just have to stay one lesson ahead of the student situations" :P ) ...

i regularly build my openELEC images and my android images so that im up to date with the latest commits, i was wondering if it was possible to do the same for raspbian, i tried the same method as openELEC but it was a disaster i assume because there was no config file and i screwed up the many ques...

Re: Monnitoring a solar powered pi

i do have a pic but i have no clue how to wire it up or even if i have to program the chip to begin with as i say the diagram just says "to ADC" it doesnt even mention an out from the ADC and the pi doesnt seem to have a "battsens_en" pin or at least not one that i can find labelled on any diagrams....

Monnitoring a solar powered pi

im currently looking into a project for the pi, i have a case with 4 AA ni-mh batteries in and a solar panel mounted on the back to charge the batteries, that all works perfectly, the next step is to find a way to monitor the charge thats left in the batteries and the amount of power being provided ...

Re: Overclocking success over 1GHz?

thats good enough for me then, so heat isnt an issue and i have a decent power supply (i use my touchpads charger) so that wont be a prob either, guess i can start pushing it a little more :D

Re: Overclocking success over 1GHz?

I m not new to clocking thankfully, I've been clocking pc's for many years, but once I push the voltage up it will increase the temp and even though they're a cheap device they still aren't easy to get hold of so id rather not burn it out too soon. Also temp does have some bearing on the performance...

Re: Virtuella RAM and cpu clock

I wouldn't think so, technically you could mount swap file on a usb drive but it won't help your cpu clocks and probably wouldn't make much difference

Re: Overclocking

ah ok, its not too bad really, its not like a boot takes long but it would have been nice to be able to clock in os. one thing i have noticed though is that raspbian seems to clock fine, but a few days ago i built the latest openELEC from source, it runs very well at stock but for some reason it won...

Re: Heat Sinks, Do YOU need them.

im guessing the chip doesnt contain a temp monitor as we have yet to see any actual temp figures, im not sure if ill have time this weekend as i have a few things on but im going to try and get something setup to monitor the temps soon. for those that have used heatsinks which are you using? im look...

Re: Overclocking

But I expect the versions used in cellphones don't get overclocked. i wouldnt say that, ive overclocked my last 3 phones (my current desire z runs a 1.2ghz clock up from its original 800mhz and my touchpad at 1.5ghz which runs at 1.2ghz stock) so i imagine plenty of people have clocked it when used...

Re: Overclocking

These Cambridge people that live at 69F (20.5C) all year round just do not agree with me :lol: sorry i had to laugh at that one, its not that often we see temps as high as 20C for extended periods here in the uk! but i think if you are going to overclock a heatsink couldnt hurt any, i havent found ...

mine is happily doing 850 arm freq and 475 memory but i havent pushed it any further as yet. has anyone tried adding a heatsink? i imagine small ram heatsinks stuck on with adhesive thermal tape would work rather well and wouldnt increase the size any as it would be no higher than the usb ports, the...
