Discussion forum for the BasicX family of microcontroller chips.

Hello- Is the basicX24 chip capable of recieving midi data? I have no experience with stamps at all, but I have been told that there is a problem receiving midi data, without the aid of a a buffer. I would like to send midi data to the board, using some of it to switch outputs, and also triggering a DVD player by outputing serial data. Does this seem possible? Thanks in advance for the help. -Louis Klepner http://www.expressiveimaging.com |

Been working on a MIDI controller myself. Here's what I've run into: MIDI data has to transmit at 31250bps +/-1%, but the BX-01 board (clocked at 7.xxxxx MHz) cannot hit that baud rate (it's off by almost 2%, beyond the MIDI tolerance). So, Jack at NetMedia suggested that I clock the CPU at 8.00MHz to fine tune that baud rate to exactly 31250. I just got my 8MHz crystal so I'll try it over the weekend and let you know how that goes. -r > -----Original Message----- > From: Louis Klepner [SMTP:] > Sent: Friday, February 04, 2000 3:20 PM > To: > Subject: [BasicX] midi application > > From: "Louis Klepner" <> > > Hello- > > Is the basicX24 chip capable of recieving midi data?

Please post your results, Russ. I'm also interested in MIDI applications. I'd like to roll my own "knob controller" for my Yamaha QY-70 sequencer. It's a shame this can't be done without driving the clock higher than the NetMedia will permit to honor the warranty. Seems to me that a little tweaking of the OS would be all that's needed to be able to set a 31250 baud rate. I realize this is "non-standard" but it's been used for almost twenty years now as the MIDI baud rate.
