Hi Folks.
Am working on a Mega based device found on Git. Have built one and got it working. It could use more horsepower and less hardware real estate so I've managed to get it *partially* working...

Never mind, I got over that hurdle.

Hi folks and thanks for reading.

The device has three buttons and two pots and a led display as a user interface and has the capability of being controlled remotely so therefore the code has two...

I prefer the smooth square pin of the WireWrap type. Some stackable headers I've used are pretty rough on the contact face and remind me of a file every time inserted / removed.

Honestly, I prefer these:-

Might cost more but give less trouble...

Something like this is handy in the toolkit.

Thanks neurofun. Will play with that and start a new thread if needed.

Are those range sensors polite enough to let you power them up, read then power them down in sequence so as to spread out the power drain?

I hope I'm not getting Off-topic here but a hand up from...

Any Teensy from LC to 3_6 should do it.

You need to choose a USB type Midi in Tools so the compiler knows to use it. I don't think T4 supports USB Mid yet.

This is a Windows Class Compliant Midi device driver issue in that you can only make ONE connection to a USB-Midi port. I believe that this is sorted for Win 10.

So in Win7, we're stuck with...

Couple of points from early days in RF.:
Any mismatch in the Transmitter>feedline>antenna arrangement can cause the feedline to radiate energy. Sharp bends in the feedline are best avoided.

Have just finished testing the same mods on an earlier MEGA based controller. Cleaned it right up. Next, copy paste same into another MEGA based rig featuring many more pots, multiplexers and a pile...

Thank you again Nominal Animal.
Following on from my previous post, I've played with and implemented your suggested code and it works. The quantization error you highlighted had made itself obvious...

Thank you Nominal Animal for your thoughtful response. I've not considered using log pots and usually don't if looking for decent behavior in audio for level or pan. Even so-called linear pots are...

Greetings everyone.
Thanks in advance for reading. Am working on an ever evolving Midi controller seeking advice using the map() function for pot calibration.
Before I added map() to the mix, I...

Thank you for your thoughts vjmuzik. I get the idea, will look into permutations and combinations at some point. TE's offering looks like it would work too. I've got it sorted using Copperlan to...

Thanks guys, that helped put things in focus leading to some exploratory plug jockeying:-

Arturia's BSPro, class compliant, single client. Have usually used it's Din for Midi so had not previously...

Hi folks. I've been building some USB-Midi interface/ controllers using LC's and 3.2's. and although everything works as intended, Ive found that I can only make one single connection to a...

I used a 5mm "opaque" Neopixel. Roughed it up with some fine sandpaper to mute the point source some more. Painted the outside with a silver felt-tip and set it about 6mm behind some 2mm clear...

Some years ago I decided to build a pocket Audio Monitor for vocal training and other portable sound reinforcement applications and here's where its at:-

Thanks GremlinWrangler. Five of the devices require their own wallwarts due to their power consumption or other idiosyncracies and four are not designed to work out of a hub. Ok, will damage a cable...

Hi everyone.
I need a USB device insertion sequencer so I'm thinking of a TeensyLC in a box with a row of USB-B connectors on the back, a corresponding row of Host sockets on the front with the LC...

Oops, sorry folks.



The iConnectivity - Teensy Midi connection works for notes, CC's etc, but unfortunately not Sysex.

Finally, off the bench. My 5 - pedal Midi controller/ interface.

Is there a way of doing that without a USB Protocol Analyser?

I'm using an iConnectivity MIO-10 and have run into the same issue with it's USB host not recognizing Teensy multi-cable USB Midi.

The MIO-10 ordinarily recognizes multi-cable class compliant...

I've stripped a range of organs for the optical expression pedals and a Hammond (80's) foot keyboard duly connected to a Teensy LC. I've noted that some more "modern" (80's) organs may have multiple...

Following up on post #10. Have confirmed that the USB3 card is the Sunix USB 4300NS featuring the NEC uPD720201.

Am out of town so can't peek inside the box, so checked supplier website and a Sunix USB 4300NS looks familiar - has a Renesas (NEC) uPD720201 controller.
Scratching grey haired head.., Sorry, I...

Had a very similar problem on an AMD quad core. Turned out that the culprit was a driver issue with the VIA USB3 host. I flashed the MoBoard with the latest Bios, disabled the on-board USB3 host,...
