hi,

i am using bascom avr and i plan to play an audio file (abt 20kb) using a controller. i am using the pc directly so no problems regarding amplification

i recorded the file converted it into raw 8bit and some 48k frequency

now i want to load it into the controller and then vary its frequency whenever a certain thing happens(that is other part of the project) and after varying the frequency again sending it back to the pc to play it

basically i want 2 vary the frequency of the sound playing in my pc using a controller

shud i use external eeprom??

suggestions will be really helpful

thanking you…

I’m still new to microcontrollers myself, and i’m not really a programmer (yet). The closest thing might be this http://www.ladyada.net/make/waveshield/.

Now while it might not quite be what you need it could help. Maybe you can get the arduino bootloader to compile and load on your item, then maybe you can upload the code. I have no idea if this is possible, just trying to help.
