Nitrus Posted April 26, 2007 Report Share Posted April 26, 2007 Hi, I am trying to build myself a controller for Ableton. As of what I need, I have a rough estimate. However, I am stuck on a couple of things... A. How do I know which PIC I need for my core? B: Which header configuration do I need?I would like LCD support, even though I do not plan on using it straight away.I just want to get my hands dirty and mess with the electronics and code portion before making any 'big' plans.

DavidBanner Posted April 26, 2007 Report Share Posted April 26, 2007 I just want to get my hands dirty and mess with the electronics and code portion before making any 'big' plans.good idea! the deeper you get into midiboxing and Ableton's features the more ideas you'll get...you'll be fine with a PIC18F452....check out smashTV's store - http://www.avishowtech.com/mbhp/buy.html lot's of great stuff there, all bundled into packs at great prices...

Nitrus Posted April 26, 2007 Author Report Share Posted April 26, 2007 I appreciate your input. However, I still am not sure about the header... Could you fill me in? In addition, could explain the differences between the PICs? Quote Link to comment Share on other sites More sharing options...
lylehaze Posted April 26, 2007 Report Share Posted April 26, 2007 Hi and Welcome,Re: Pic choicesthe 18F452 has been the "standard" since we upgraded from the 16F family. It is the assumed "normal choice" for what you are describing.The 18F4620 has more RAM and is useful for MBSEQ applications that are memory hungry. AFAIK that's the only project so far that has been "expanded" into the bigger memory map.The 18F4685 includes a CAN peripheral (Controller Area Network) which is currently being considered as a fast network for connecting a bunch of MIDIBox based projects together. (MBNet?)I'm pretty sure that all are pin-compatible, so be sure to use a socket for your PIC chip. Beyond that, I'd say the 452 is the best documented option, and should cover your needs nicely.Choosing a header number?Try clicking on the "javascript header calculator", or just go with Zero. That's usually the best choice for a first PIC anyway.Have Fun,LyleHaze Quote Link to comment Share on other sites More sharing options...
DavidBanner Posted April 26, 2007 Report Share Posted April 26, 2007 device header info: http://www.avishowtech.com/mbhp/idinst.txtif you are only using 1 core you don't need to worry about IDs, just pick the type of LCD you are going to use and make the choice as to the header...info on PICs: http://www.midibox.org/dokuwiki/doku.php?id=mios_pic18f4620both of these links were lifted from smashTVs site - check it out, digg into the information, read everything and learn lots of stuff you didn't even know would be useful at the same time ;) Quote Link to comment Share on other sites More sharing options...
