Guest Da5id Posted March 31, 2003 Report Posted March 31, 2003 Hello all, this is my first post.I noticed some discussion of a USB interface for the MIDIbox. Well, this might be kinda a hackish idea, but over on LinuxFocus, http://www.tldp.org/linuxfocus/English/index.html they have a recent article that involves modifying a serial LCD panel for USB use. The chip in use is a FT232BM from http://www.ftdichip.com and it looks pretty simple to attach this to the COM module for MIOS. I don't know if a Serial port MIDI driver would work with this configuration, but I thought it worth mentioning.Thanks for the very interesting website! I just started making my own PCBs, and I'm just itching for projects. I think I sumbled accross the right place!!!--Da5idPS- here's the link to the article: http://www.tldp.org/linuxfocus/English/March2003/article286.shtml Quote

smashtv Posted April 2, 2003 Report Posted April 2, 2003 'sup midiboxers!For those in the experimenting mood who want to DIY instead of buying a keyspan USB-serial, the FTDI chip mentioned in this thread is available on a carrier board (with USB socket) that fits a standard DIP socket. It isn't cheap @ $25US, but it translates RS232 serial easily with no other parts, and has royalty-free drivers for all platforms.See http://www.dlpdesign.com/usb/usb232.html for info.Later! ;DSmashTV Quote

Jack Posted April 10, 2003 Report Posted April 10, 2003 Here are two links!Who can programm a USB to Midi converter on a PIC?I don't know programming at this moment. But i will do it when I can.http://www.usb.org/developers/devclass_docs/midi10.pdfhttp://www.microchip.com/1010/suppdoc/design/netdez/usb/index.htmhttp://www.usb.org/share-cgi-bin/search?method=and&format=builtin-long&sort=score&words=midi&exclude=%2Fforums Quote

plus Posted July 8, 2005 Report Posted July 8, 2005 SMD :-/It's GOOD!!! FT232BM is so compact/. It has so little number of pins (32). There are a lot of different projects on this IC in Internet. But I can't find any project with USB-MIDI adapter. I think it's very interesting thing for many of us. In additional it becames more cheaper then earlier (about $5).Can anybody show project on this topic? I'd be glad. :D Quote

Yes it is good device, but AN2131SC has more number of pins (44). Andsoldering process is more diffuculty for beginners. FT232BM is more wide available and itsprice is lower. Dimentions are lower too. I think this chip is more interesting.About second link. You give answer on this own question - "not working at the moment..."But it's a good idea. But when it will be ready? Quote
raphael Posted July 9, 2005 Report Posted July 9, 2005 About second link. You give answer on this own question - "not working at the moment..."But it's a good idea. But when it will be ready?Probably never... There is a silicon bug in the latest revision of the 18Fx550 PICs.Read this forum article:http://forum.microchip.com/tm.asp?m=85120BTW: I've already soldered two AN2131SC modules without problems (Ok, soldering is not so easy ;)). And they have two MIDI INs and OUTs! Quote
plus Posted July 9, 2005 Report Posted July 9, 2005 BTW: I've already soldered two AN2131SC modules without problems (Ok, soldering is not so easy ;)). It is'nt problem for me. I have soldered too many ALTERA's 100-pin chips. But I'm not a programmer... Now I'm selling out my ordinary MIDI-adapters. But I want to sell more popular now USB-MIDI-adapters. So I try to find cheaper desigion of this problem. May be it will be device on AN2131SC. Quote

Exuse me! I'm not a programmer but I'm an old electronic's designe engineer. My goal is to analize a lot of information. And I must make up MY USB-MIDI adapter. I know one programmer and think He can help me. But it's not a crime to get any kind of information on same topic! Quote
TK. Posted July 11, 2005 Report Posted July 11, 2005 Perhaps you can use this chip with the serial port driver of Yamaha http://www.yamaha.co.uk/xg/html/software/s_serial.htm, so that no self-written driver is requiredBest Regards, Thorsten. Quote
