Post by thread:[OT]: My new car MP3 controller

Tal, Congratulations, Looks GREAT!! So where is the music stored? Does the pic do the decoding?

Very nice! Funny, this whole PIC thing started with me cause I wanted to build an MP3 player as well, but for a car. Also when the whole Linux thing started. However, the one thing that put the project on hold was locating a PC104 or other SBC with 4-channel audio. Maybe I'll pick your brain when I revive the project. :-) Cheers, -Neil. {Original Message removed}

It looks nice. The only thing is that it seems to exclude the use of a real keyboard. Is there a particular reason to not do all the I/O straight through the serial port? I would think that making a program on the computer side from one port would be simpler than handling three ports, and it would involve less wiring. Jeff {Original Message removed}

Jeff I thought of it when I design the wiring, due to the flexibility I want to gain, I leave it as it is now. Regards Tal Bejerano AMC - ISRAEL {Original Message removed}

I tell you, using a PIC 18* and the new Micronas chips is the way to go. leave these PC's and OS's out of it. small tight code. slimdevices has exactly what I'm talking about. use the pic to read the CF and allow you to select. (maybe build a file list in eeprom on each CF insert.) you menu through (VFD or LCD)...

When you have an Email client, Web browser and Word processer (and Doom) on a PIC, then I'll throw my PC in the bin. By then, were have Picdows - Windows of the future. {Original Message removed}

Actually, until there's an assembler that runs on a pic to make pic .HEX files it's never going to happen -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads

Please no! PICs don't crash. I don't need that feature. Peter -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

How about 18Fxxx which can do this to itself. Genetic code anyone ? Who knows what a PIC could teach itself ;-).

You've still got to get your 'original' code onto the PIC. I suppose you could attach a couple of switches to the programming pins and wiggle them up and down really fast to load in a program but it feels a bit of a step back to me. In the good old days, we use to write a monitor program for say a Z80 or 6502. The monitor prog, supported a HEX keypad and multiplexed LED display for example. Using these, you entered your program into memory and then ran it. When it crashed, you hit the reset button and your monitor prog sprang back into life so you could edit your program. I suppose you could do the same with a PIC ? The real pain in those days was you had to do all the assembly by hand. {Original Message removed}

Except they often hosed their own programs when crashing (I used CMOS ram for program storage also on 8051 and Z80). >I suppose you could do the same with a PIC ? Hmm. A 18F could do that. >The real pain in those days was you had to do all the assembly by hand. I built two microsystems on breadboards using soldered wirewrap wires. One is still on my table (80C51 + EEPROM + RAM). I hate wirewrap and I timed myself, soldering is faster. I was thinking along the lines of inputs, outputs, and a 'carrot/stick' input. Every time the pic does something bad with its outputs push the stick button. Eventually it should start to do what you want it to do. A stick push would have the program alter the production that led to the bad state using a random generator. You could take this to the next level using an analysis layer that would add state spaces to the state machine when there is too little success. Such an algorythm should develop a 'brain' just smart enough to solve most of the problems as desired by the teacher. I have posted some ideas on this some time ago in this mailing list, involving a small robot. I will try to find the thread if you are interested. Peter >{Original Message removed}
