  1. YEAH! My code change worked! The Floorboard is putting out 13 notes. BWHA-HA-HA-HA!  ;D ;D ;D ;D ;D
  2. Did the code changes for pedal 13 this morning. Now all I need is some bench time...
  3. Fair enough. I was just venting because I thought the response was rather snide. Perhaps it's a cultural thing. I'll be happy to post results. There's a thread in the troubleshooting forum where I documented what's happened so far.
  4. Wrong. My question was hardware. Your license is revoked and your gas is hereby turned off. I figured it out on my own, no thanks to you.
  5. IT WORKS! ALL RIGHT! ;D ;D ;D ;D ;D ;D It was the stupid keyboard I was testing with! Next up:   1) Add note #13   2) Rig my organ pedalboard to the breadboard What a kick! This is so cool! This thing rocks!!!!!!!!!!!!! :o :) ;) :D ::)
  6. Raphael: Compiled with 16F877 include Code shows MIDI channel value as 0 ??? Is that valid? Crystal is pulsing Did LED trick I found in the MIDI diagnosis area. IT FLICKERS! Only have 4 pushbuttons right now -- the ones with the 10K resistors. Are paper clips big enough to simulate the pins on a MIDI cable?
  7. AAahhhh!! Dagnabit - the include! I think I forgot to use the 877 one. Thanks, Raphael! That one I can definitely address! I'll check back in a few days.
  8. I'm working on the old Floorboard project. The circuit is breadboarded and hooked to an old keyboard I'm willing to sacrifice in order to get this thing running. So far, it's not. I'm decent at troubleshooting audio circuits, but a digital circuit is a horse of a completely different color! Assistance desperately needed (and begged for)! Here's all I've been able to figure out: I'm using a 16F877 instead of the 874 because I couldn't get any 874s that ran at 20MHz. I compiled the program with the "USE AS KEYBOARD" option. It compiled and linked flawlessly. The PIC also was loaded flawlessly. The circuit? Power: 9V wall-wart feeding a 7805 with a 1000uF cap before and after. Rock-solid 4.99VDC. Also got 4.99 at all Vdd pins and the pin that feeds +5V to the MIDI output. Output: NOTHING! Keyboard silent. Also tried putting an oscilloscope on the PIC output, hoping to catch logic pulses or something. Also nothing. Could I get some advice on troubleshooting this thing, please? Thanks!
  9. Umm, Doc? How would posting a question about the foot controller in the MIOS area help? I'm not asking about MIOS. IIRC, the controller doesn't use MIOS...
  10. ??? Umm... hello? Did I ask a forbidden question or something? Is there some protocol for posting questions that I didn't follow? If so, I apologize. I see that most posts concern the MIDI Box. I did look at some of that, but it's more than I need. All I need to know is if it will work to add inputs to the floorboard as I've described. I can code the change. For assembler, that's pretty clean code!
  11. Hi. Embarrassed newbie here. I live to play guitar, but I make my living coding software, so PICs don't scare me too much. I need to make a set of bass pedals to use at church. Since I just snagged an Alesis NanoBass, that dictates that my project will take the MIDI approach. The old Floorboard project here looks like it's 97% of what I need. I just have one teeny, tiny stupid question. Upon reviewing the button code with the USED_AS_KEYBOARD assembler option, I note that this will generate notes C through B. I'm hoping to adopt an actual organ pedalboard for my task, so I have 13 pedals to give me a full octave. I need to implement one more pedal. Is there anything keeping me from creating a modified version of the button code that starts from the D3 pin instead of the D4 pin and implements a 13-bit instead of a 12-bit shift register? Would it be OK with the designer if I did so? This unit is for my personal use only. I just want to build it, get done and get back to playing! While we're on the subject, would it be possible to add switches to some of the other unused pins to implement multiple octaves? I hope my writing is clear. Electronics is not my strong suit and my writing is very idiomatic when I'm excited about something. Thanks in advance for any help!
