Bad news for me. I wish there'd been an option to leave the lock bit unset during development etc. No choice now but to rip it apart and put in a new Teensy 2.0, saving the existing one. Oh well, this is my excuse to socket it, which I should have done in the first place :-)

Does anyone know if it is possible to extract the hex code from a Teensy 2.0 in such a way as it could be used to reprogram the same or another Teensy 2.0? I'm using the Teenyduino IDE. I DO have the source code, but I've lost my Arduino installation due to a head crash. I had some modified...

Thank you everyone for the replies & great ideas. I've been out of town for a funeral, and then sick for a week and totally out of it. I'm going to try some of the stuff here & see if it improves my current project. I'll post back.

Thank you everyone for info & participation in this. I've by no means lost interest. Had to drive 8 hours to an unexpected family funeral last week, came home w/ a 102 fever. Been down for the count. I'll try to reduce my code/hw to the minimum to demonstrate a very peculiar phenomenon that...

Without going crazy w/ details, I have an arduino app which monitors incoming MIDI data from a number of h/w MIDI controllers, and retransmits CC's on 6 different channels ( to six connected h/w synths). I've been trying to troubleshoot a maddening problem, in which it works well with some...

I'll caveat the following w/ the disclaimer that I'm no expert on this, lol. A couple of things, in no order. All of the solutions I found online for pot jitter where MIDI is concerned (i.e. you absolutely CAN NOT have the mcu transmitting cc's when no one is moving a control...) involve...

Thought this might be of use to some of you struggling w/ jumpy pots/MIDI cc values, etc. The twist is adding/subtracting a small % of the total raw value IN ADDITION to the usual fixed value. I noticed the fixed values just weren't enough at raw > 900, but increasing the fixed values then...

Thank you, Adrian. As many times as I've referred to that schematic when using my Teensy 2.0's, I never caught the text about the 3.xx resistors. Cripes, I'm getting old...

Hi, My understanding is that the 3.xx series is fundamentally a 3v system w/ 5v 'tolerance' on the digital pins. I'm currently using a Mega 2560 for it's 4 UARTS, but it's running out of steam for my app. Given the variety of MIDI h/w deviations out there, can the the Teensy 3.2 safely...

Yeah, I put an ohmmeter on them, they're ~220 ohms, but, like I said, I have a separate setup on a breadboard w/ different 220 resistors that's doing the same thing. Wouldn't a 7404 be able to sink enough current if the UART was "weak"? Or would I need to do that w/ a transistor? What's odd, is...

Paul, I posted before I saw your reply. Yes, checked those voltages first, they're 5v on the nose. Using a very good supply, as well as USB power when programming. No change.

Thanks for your help RE: "It will probably help whoever is going to end up helping you the most with this if you post the batch of code", I'll be happy to post all that if you need it. The reason I didn't is that if I begin to suspect a h/w issue, my standard procedure is to eliminate as much...

Hi, I have a plain-vanilla Teensy2.0-based MIDI controller (using the example schematic from this website) whose MIDI output is only recognized by about half of my USB-based computer MIDI interfaces. The most recent one I've discovered a problem with is the MIDI Mobilizer II for iOS on an...

Paul, I just ordered an LC & a 3.1. Can you point me toward any examples of merging MIDI data w/ two UARTs? I'm pretty green when it comes to serial i/o, especially async stuff...

I'm not at all opposed to using an LC or 3.1, I just wanted to try it with stuff I had on hand. Do you guys know of any example code for merging two DIN MIDI inputs? I currently use the MIDI library "Thru" function for merging one DIN input w/ the MIDI data generated by the Teensy via pots...

I know there are commercial products that do this, but space is at an absolute premium on my pedalboard, and this has to be tiny, or built into an existing enclosure. Can this be done w/ a Teensy 2.0 since it has only one serial Rx input? Thanks.

Guys, I'm really sorry, there seems to be nothing I can do to get this forum s/w to notify me via email of new posts. I didn't know you replied. Nantonos, thank you kindly for the links & the example code. That's what I needed. I was also evnetually able to find some similar example on...

I'm sure I'm gonna sound ignorant, but prior to posting here, I looked though all the included Arduino/Teensyduino examples that had anything related to "MIDI" in the name, and I could find no example of code in which incoming DIN MIDI data is echoed directly to a DIN MIDI output, with perhaps...

Hi, I've been using Teensy's with great success to implement various controller schemes. However, I've not yet tried to use it to filter/process a realtime MIDI data stream. I play MIDI guitar, and would be working with a channel per string consisting of NoteOn-Off and pitchbend data, as...

Hi Paul, It's not a Teensyduino issue. As near as I can tell, the most recent Arduino IDE (1.05xx) includes a number of Adafruit libraries that may/may not be current. There are a number of Adafruit I2C LED/Matrix/7-Seg code exampleslibraries that require different versions of certain...

Thanks. Interesting. Even though I had "instant email notification" checked for this thread, no email. Hmmm. In any case, I did search before I asked, found plenty of "links" to older versions, but they all point to the same download page, which only has a link to the most resent version...

Where can I find older versions of Teensyduino? I need to run Arduino 1.04 due to some Adafruit library issues. Thanks.

Dr. John, thanks for the info on the IntervalTimer library. I'll look into it. I found the threads you mentioned before I posted here, as well as quite a few similar ones, and lots of info on going the other way, i.e. MIDI beat clock to various timing signals. But nothing functional, or tying...

Hi, I acquired a TC Flashback X4, which is a nice looper/delay in that you can utilize the looper and delay simultaneously, i.e. loop a "delayed" signal, change the delay time/feedback, overdub that signal, etc. All good. Except for one detail: The delay Tap Tempo button becomes...
