johnh Posted January 20, 2004 Report Share Posted January 20, 2004 Greetings, At 9:46pm PST my first MIDIbox core module requesteda sysex dump. I'm very happy. Thanks to SmashTV for thegreat kit!!! I assume the first step is to load the new MIOSand then start into programming. I want to create an appthat translates certain sysex messages into program changemessages for my pipe organ project. :) ---john. Quote Link to comment Share on other sites More sharing options...
Guest tew Posted January 20, 2004 Report Share Posted January 20, 2004 Congrats! My girlfriend is soldering up our core module now. (She's got the steadier hands, and there are some small parts!) I'm still trying to figure out how we'll power it up, since we don't have a socket to plug our wall wart's output into. We're also lacking a MIDI cable. Maybe we'll get a SysEx request out of it tomorrow.Starting from scratch with the MBHP as our first MIDI project is proving to be quite an adventure.

arumblack Posted January 28, 2004 Report Share Posted January 28, 2004 yeah! now mine lives finally! and i think i got an app loaded. not sure as i don't have lcd yet. well i have one, but can'y figure it out. the datasheet says it has 20 pins and it doesn'tit's got 14 and 2 for el backlight. this isn't my permanent display, but i thought i could get it to work.it has a hitachi hd44780controller chip on the back. i think i can figure it out, butwill it work at all without all the wires connected?i don't want to have to solder and desolder a million times,but i think i found the power pins. any tips???

Guest tew Posted February 9, 2004 Report Share Posted February 9, 2004 Hehe, there's nothing like that feeling when your project wakes up, winks at you, and says "hello world". Tonight was the night! Let me tell you, there was a scary moment in the lab when I turned everything on and nothing happened. The ladyfriend says I turned an awful shade of red. A crazed session of debugging ensued, and I diagnosed a problem with my DIY MIDI-Gameport adapter, based off the plans at http://www.borg.com/~jglatt/hardware/pc_intfc.htmI'd neglected to connect the "to ground" in the lower left with the "to ground" in the upper right. I guess I was just supposed to know to do that.Then my core module was still sitting silent. On a hunch, I reversed the pins of the MIDI out part, and, then, success!Next up is connecting the LCD, which looks to be relatively easy. Some older photos show pins for LCD contrast adjusting pots, but I don't see those on my PCB. I might also have to connect up a resistor in series with my backlight leads, as the datasheet says it only wants 4.6 volts. Quote Link to comment Share on other sites More sharing options...
arumblack Posted February 9, 2004 Report Share Posted February 9, 2004 Don't you have the trimmer pot's right on the core module itself? those are for the lcd. Quote Link to comment Share on other sites More sharing options...
