Well, it is an option since you only need to change the device include block and pins. PIC18F4458 should be good (2kb ram). I see it runs up to 48mhz which is great. Will USB use a lot of the 2kb ram? This could be an issue. Are you planning to use USB? > I want to use a PIC16F887 chip with 2 Hard Drives (using the CS0 and CS1 > pins > for selection), and a second PATA interface for later use. that is not the purpose of those pins, but you are right, it should not be difficult to change the code. You can see the variable "pata_hd_slave" in the hard disk library. It is untested, but changing it may change between master/slave. > I'm sure it is... but as I said in my previous email...

If you add radio, one PIC can control the hard disk and mp3 player. A separate PIC can control the radio. No data transfer needs to be done through each of these, you just need a way to switch the headphone jack audio from MP3 to Radio and others. Doing data transfer is probably a waste of resources, but maybe you have another reason for doing so. You will need resources/speed to keep up with high data rate music files. I think you can use VS1053B for "audio in" and microphone. > Also... this isn't supposed to be a portable media player... far from it. > This device is going to be housed in an old stereo receiver box. I was just letting you know my plans. I would like to complete a portable player, and also a player for my car. The player for my car will hopefully have WIFI for updating songs over night as I sleep. I also have no spare cash, this is why my project remains incomplete. I'm not sure if the GLCD thing is going to work out for me, it is too much for PIC. I'm going to try PIC18F46K22 at 64mhz. I think drawing text may still be slow. I was even thinking about going with a dedicated GLCD graphics device , does anyone know any good ones? I have also seen on the net that some people put more then one 4x20 LCD beside each other to make a big lcd.
