Hi, if this ends up posting, that will be pretty exciting. Has anyone ever posted on this topic from the nspire? I couldn't login.. My password contains umlauts.

I don't know the mechanics of Omnimaga and if editing a message bumps a topic. So just in case... You don't get notified per mail but you will be notified if your in #omnimaga. (I think) Any ideas. I know 192.168.0.1 is the router address for wireless access, is there a different method to connect with Ethernet? You need to specify a dns-server but it's easier with DHCP: auto eth0
iface eth0 inet dhcp

Everytime the (fast)timer fires an fiq, I toggle gpio 4 and set the timer value. For instance, if pwm=40, I set the timer to 40, after toggling I set the timer to (256-40). So I get a pwm freq of about 33000000/256 Hz, but for whatever reason I have to shift the timef value one left. If pwm is updated while the gpio is on, the off period is already computed with the new value, so it should atleast feel faster  SD card support might be good for nspire-linux, the usb port is slow as hell.

Running, and then disassembling, diags software Only running I curiously explored the menus and tried to touch the ports on the back and noticed it recognized my fingers. There is MOSI, MISO, too (SPI). Somewhere there's even SD-Cart support (D0, D1, D2, GND?)

It would be nice if the battery pack was removable so that I could let it completely reset. It is, just be careful, the cables are very thin.

My friend accidentally shorted every pin and it didn't reset.. One reason more to find out what the pins are.. I'm sorry for your loss  Does it still work with linux or can't you control your calculator at all?

The audio player utilizes the GPIO pins at the dock connector, allowing it to achieve a sample rate of 10kHz! With the newest version you can load wav files with any samplerate you want. The limit is the pwm-frequency (64 kHz), it starts to sound nasty then (but untested, 44,1 kHz works perfectly) music should've been rickroll Without the video it's boring

Though just wonderinjg, would it be possible to change the volume coming out? Because I connected a headphone jack and my headphones, and it is way to loud Yes, by making the pwm off period longer. I'll try it and upload when ready Edit: Nope, pwm gets too slow if too quiet.. You can hear it as a high-pitch squarewave then (annoying as hell)

yes, it jumps over every chunk until it finds "data".

Great! BTW: Try it with 32000 nevertheless, it sounds SO MUCH better

Audacity should ask you after the file save dialog. There's a delete (or remove or similiar) button on the bottom right
Edit: Bug resolved

Ok, it seems to not work with 10000, could you try it with 32000? I'll try to find the bug  Edit: Found: Try to delete the author, title, track information.. My wav decoder tries to interpret it as the file length

Strange, does escape still work?
I made a reset on my calc, opened a wav in pwmtest, pressed escape, opened it again an it plays as it should.

Okay, I went to audacity selected stereo to mono, changed it to 10000 saved it as other compressed file, unsigned 8 bit wav, and sent it to my calculator.
The player just stays at zero seconds now. Hmm, theres a bug: You have to start it twice after rebooting..

This is much faster, but for some reason this still isn’t fast enough for vocals. Whoops, now I see..  It's really just 16000, I swapped the files.. sorry  16000 is indeed a bit low, I'll search for a better way to load it (Fast timer No.2 maybe?) And *yay* german
* Sorunome isn't alone anymore Ich bin hier doch schon 'ne ganze Weile xD I just like how much stuff is made for the nspire, that makes me wish I had one >.< Wishing alone doesn't work (except for christmas), you may have to buy one Edit: Newer version: -WAV support (mono, 8-bit pcm) -samplerate up to 33 MHz xD -fixed small bug with GPIOs -Max file size = free ram
