    How to choose a MicroController

    thanks for actually taking your time to reply.Yeah, i looked up a lot of videos and articles on the whole process of reading sd cards and playing audio. I found a good video on how to do the sd/microcontroller communication through serial peripheral interface. (so at least i no im looking for a controller with SDI/SDA and SDC pins) It also explains the whole wakeup and communication protocols to actually read and write data onto the sd. The whole playing audio business is what gives me a headache right now. I am a luthier and don't have any kind of background in computer sciences, except a bit of playing around in c++ and basic.I actually started out by thinking about getting an arduino clone but for my purposes every inch of space i can save is a big plus. Thank you very much for the r...see more »thanks for actually taking your time to reply.Yeah, i looked up a lot of videos and articles on the whole process of reading sd cards and playing audio.

Thank you very much for the recommendation. I will order one Teensy and just try to figure out the whole thing step by step. If you ever get around to writing a follow-up on your article i would be very interested to give it a read.

    How to choose a MicroController

    I am totally new in the MicroController thing. I have some experience in music electronics and basic programming.Now im looking for a small solution to add sampling to my Guitar. It would have 6-8 simple keyboard switches that trigger a sample from an SD-Card that then goes out to a simple audio jack output. Also it should be able to power three leds (only one active at a time). Programming doesnt need too much memory since all it will do is: two buttons allow to go up and down through the three banks. The other buttons are each assigned to one audio sample on the sd card for each bank. The leds show which of the three preset banks are active. The other 4-6 buttons trigger the sample, pull it from the card and play it to the audio jack.What kind of microcontroller could you recommend fo...see more »I am totally new in the MicroController thing.
