Thanks Sven... Morteza

13 Jun 2013	Simulink Support Package for Raspberry Pi Hardware Support Package Installer file	Hugo	Sorry for the answer delay Murat. I will see if I can show you the model because is a university project and I dont know if my team allows it. If yes I will contact you ;) thanks I want to have output sounds by GPIO but I think that will be impossible due to my sample time of 48000. I test the ports with a simple square at that frequency wave and a oscilloscope, and the PINS coul not output a steady frequency. :\ Another thing that I do not understand was the input audio block. If the raspberry does not have input sound ports how simulink have an input sound block? I think that for beginners the documentation could be better...	Comment only
11 Jun 2013	Simulink Support Package for Raspberry Pi Hardware Support Package Installer file	Murat Belge	Hugo: Can I have your Simulink model? This looks like a bug. I'd like to make sure it is fixed.	Comment only
08 Jun 2013	Simulink Support Package for Raspberry Pi Hardware Support Package Installer file	Hugo	I figure it out the problem about the sound. I fix it and the sound is now quite nice :D However, through other outputs the sound could be better? Like HDMI? Another point, in my model I have 3 sounds outputs. I wanna that this 3 data sets go to the GPIO pins to control each one individualy. I try a simple model including a sine wave, a relay, a data conversion to boolean and a GPIO pin. No problem, I sent the model to raspberry. When I test with my model an error occured and said to contact Mathworks. The error was: "Unexpected or internal error encountered in "in CGIR: b:\matlab\src\cg_ir\util_cg\cg_sanity_checker.cpp line 411: sanityCheckLValue: expression producing non-pointer type used in L-value context ". Please report this to MathWorks if you can cause it to recur". Erro print from my workspace: https://feupload.fe.up.pt/get/nHLDjoC8w5137mK My output is a vector with 32 samples from -1 to 1. I use the following blocks to peform the conversion to GPIO pin: relay, data conversion to boolean and a unbuffer. Could you help me Murat? :\ Thanks again	Comment only
08 Jun 2013	Simulink Support Package for Raspberry Pi Hardware Support Package Installer file	Hugo	Murat: this sample rate, in fact little fast, is the output of a much complex system that I have been working. I simply passed to raspberry and after some time the sound simply stop. I had not thought about the sample rate but it solves my problem regarding the sound stop and noisy! And thanks for the tip of speed/work improvement :D Yes you are correct, the range is 2^15. I put it wrong. Now I need to improve the sound quality. In my system I work always with a sample time of 48000 so I cannot improve more to obatin more precision on the output wave. The wave is also a combination of many frequencies. Another option could be improve inside the raspberry. With the conversion to 16 bits, the sound quality, which is normal, is not so good. So I search for a while and I can use the sound either by, 3.5mm jack, HDMI or a output sound card via USB. Using another port is possible to have better sound quality or the ALSA block and its 16bits limit me to the sound that I have now? I wanna try if I can have a similar sound like I listen when I run my model on my PC. Thank you Murat for your help, really! ;)	Comment only
07 Jun 2013	Simulink Support Package for Raspberry Pi Hardware Support Package Installer file	Murat Belge	Hugo: I think the crackling / popping sound is originating from the fact that the sample rate of the model (32/48e3) is too fast for the Linux OS to keep up. It is strange that the ALSA driver itself does not report any underruns. In any case, I changed the frame size going out of the Sine Wave block to 256 that got rid of the problem. There is one more issue in your model in that the input to the ALSA Audio Playback function must be a signed int16 which means that samples are in the range [2^15, 2^15-1). Your MATLAB code was scaling the samples to 2^16-1. Finally, you do not need to use a MATLAB function to scale the sine wave. Change the amplitude of the Sine Wave block to 32000 and use a Data Type Conversion block to convert the output to int16. Get rid of the MATLAB function block. Note also that adding the Data Type conversion block before matrix concatenation reduces the amount of work CPU is doing by half when doing data conversion.	Comment only
