The default '''mcf''' is 16000 Hz. This is the frequency at which the PCM audio clock will run. The actual PWM output is derived based on this value, so it should be higher than the desired output frequency. For small duty cycles or for higher frequencies (e.g. above about 8 kHz), you may need to increase this value to get a more accurate '''real_frequency'''. Due to rounding, it may not be possible to get your desired output rate. Compare the contents of the '''real_frequency''' file with that of the '''frequency''' file to determine accuracy.

Want to compile your own modules? Or change the configuration of the kernel? [https://github.com/adafruit/adafruit-raspberrypi-linux Advanced users can find our kernel repo here]
[http://adafruit-raspberry-pi.s3.amazonaws.com/OccidentalisV02Kernel.tgz We also have a Kernel+Modules tgz file], after you've copied this over to your pi, run the following commands
* tar -zxvf mykernel.tgz
* sudo mv tmp/kernel.img /boot/
* sudo cp -R tmp/modules/lib/* /lib/
* rm -rf tmp
AdaFruit ne dispose pas de tutoriel expliquant comment télécharger, compiler or installer un kernel linux.
