i am getting a little spacy in my old age and can miss things like the fact that you did say no link found i was sort of looking for a long winded reply not just a few words :)

sorry i left out the link but i had enumerated the supported types in the posting so it is really redundant but here it is http://www.kinura.net/mid2pianocd/

you posted a blank reply

I have a friend who would like me to write Arduino code (Ideally for teensy since it has good MIDI support) that will decode one of the audio encoded MIDI formats used by the modern player pianos. I Am connected to the guys who know a lot about this stuff and they could probably provide some...

datasheet link for diode got mangled, here is another https://pdf1.alldatasheet.es/datasheet-pdf/view/191390/WTE/SR3100.html

yes added diode. https://datasheetspdf.com/pdf/624752...onics/SR3100/1 it worked until i moved parts around. at this point i think the only thing wrong could be the back EMF causing noise. however before i replaced the breakout board and all the wires it will killed at least one and maybe two...

i made a similar test and ran it before but forget if i ran it on 3.3 or 5 volts. ready to test when i get a minute. trying to make some progress on getting ready for my big solar array arriving soon. means major organizing of workshop to make room for stuff.

so even with that same display unit, different boards could do different things on the data lines? i read somewhere that the oled does work on 3.3 but other places that it needs 5 volts. ill try it on 3.3 and see myself. also if the 3.3 volt reg on the teensy is overloaded does it shut down...

Final question before hopefully not burning up any more teensies I am almost ready to try again. I have moved the fet board far from the teensy and have ordered an isolated version. the only load on the 3.3 volt regulator in the teensy LC is a pot as a voltage divider. it draws .6 ma. I am...

thanks, a very useful page.

i did just what you said, 1/4 watt through hole and plastic cap will see how it works. I have another project that I am actually selling. It has a similar (but a gear type) motor going in two directions using and h bridge. Never had a problem and all the stuff is crammed in a similar small box...

Thanks Paul for the suggestions. I moved the FET board to right near the motor so only unswitched DC goes past the signal wires. I will definitely add the diode before trying to burn up another teensy. I do have a scope but i would have to run the teensy fryer with the motor connected to be able...

there are 10 uf (more like 7 and 8 ust be 20%) on the input and output. The teensies do not fry immediately. I think it is after the motor runs for a little while. I had the exact same setup working for hours. Only a problem once I put all the stuff in a small box and have the motor leads...

The whole thing is powered by a 12 volt power supply. The teensy is powered by an adjustable step down converter that tests as a steady 5 volts. The fet board is a no name but here it is on ebay https://www.ebay.com/itm/133969622565 I attached a PDF drawing that shows all the connections to the...

Forgot to mention that the display is powered with 5 volts which is what all tutorials suggest. The teensy LC is not 5 volt tolerant and it is possible that my initial success was with Teensy 3.2 but they are not available and I burned up my last one :)

I have a circuit and code that worked fine in testing but now that I have packaged it all I does is burn up teensies both LC and 3.2. The attached PDF shows the connections to the teensy. Sorry I am not good at drawing schematics. The project is a thread winder. It is quite simple. A target is...

I have shipped some devices with teensy LC boards in them. The board is tightly packed in a box and is covered with braid and tape to isolate it from other stuff. This is sort of a prototype for testing. I found that the program button got pressed inadvertently so I cut it off. Now I want to...

I should have said I have always said that it is impossible to understand the state of mind of another (or yourself at another stage) until you experience a very similar condition.

You are right you only had part of the story. I did not explain my crippled mental state. My most recent posting explains all of that. I got this reply just after I finished posting. Again,sorry for any time that my confusion has wasted. I will try to figure out how to better address my mental...

Sorry about all the time I wasted of others OMG I feel like such an idiot. There is nothing wrong with anything. I also wasted a ton of time for myself. The serial print I was seeing was the reading of the SD card and printing it. This was all my fault but I do have an excuse:) I have stage...

my code has the for statement commented out but when I load the program it runs the old program. the folder in which the bin is supposed to be is the right one. i even copied the text of the source to a new sketch and it builds another code folder and again the bin is right. Again the strangest...

I bought a 3.6 a long time ago but never used it. I have an SD project so tried it. It is behaving very strangely. I looked on the forum and elsewhere but can not find an answer. I tries doing the 15 second reset thing but it did not work. Here is the history: I succeeded at getting the...

Thank you Paul, this "helpful" feature got me too but fortunately there are geniuses like you to help us less nurdy guys :)

i am also interested in receiving MIDI data from one USB port and outputting it on another USB port. Any ideas or examples on this?

This question has been asked a couple of times over the years with no answer. I am using the encoder library from the latest teensyduino installation. I am testing with teensy 3.2. I understand from previous "answers" that the default with encoder is to use interrupts. That is not the issue. The...

will ADC be available for teensy 4 soon will the ADC library be available for the teensy 4 soon ?

I am using a few endcoders in my project. Three are very slow mechanical types and one is a high speed optical. I think it is about 1000 counts per revolution. Everything works fine and because of the nature of my sketch it is not really critical if I miss a few steps now and then. I would...

i need to use i2c for both the audio shield and also for the Adafruit_VL6180X i thought i needed to use a different i2c bus for each. the info on the audio shield suggest that the i2c can be shared but does not give details. can i just use one bus and it will all work out just fine? i can not...

other options i just want to use a different bus. can i edit the wire.h in some simple way to change the address?

i think i need more thorough instructions. i copied the Adafruit_VL6180X library but i don't know what you mean by rename it. do i just rename the folder that contains the .h and .cpp files or do i need to change their names as well? i have tried renaming and relocating everything but still can...

what do i need to do to get the i2c_t3.h library to work with Adafruit_VL6180X

I have a Gecko 320X that i am controlling with a Teensy3.x (varies depending on the needs for a particular application) this may sound a little strange but i want the servo to act like a stepper and just lose steps if the motor can not accelerate fast enough. i do not need absolute position...

i removed the HX711 library and installed the one from Olav Kallhovd and changed my code to work with it. seems to be just as good for my needs as the other one so no problem there. i still get the warning about the redundant define with the new library. my complaint about the warnings is that...

i am not finding the authors on either of the two libraries i have. any hints on how to identify them? i have looked at the readme files in the zips they came from and also the h and cpp code. no mention of either of these authors.

i should have made the request for another IDE separate. it is not the warnings that are such a problem with the arduino IDE. there are many other annoyances i would like to get rid of.

if i comment out one wire, it is fine as it is if any other single include is commented out. strange because this is not a problem in the original script which has one wire and encoder. it only becomes a problem when i add HX711.h is this just an annoyance caused by redundant definitions of...

I tried adding the HX711 load cell library to a working existing sketch and it causes a warning. Here is the minimal code that shows the conflict. if i comment out any one, it is fine. the warning message is posted below the code. Can I just ignore this or do i need to remove the "define" in one...

http://www.bourns.com/docs/Product-Datasheets/EMS22Q.pdf these work

no problem re-programming the teensy. it worked except that the display would go nuts frequently. must have fried the I2C lines.

i don't think there was enough energy to explode the MOV. i have had MOVs explode so i know what it is like. one flamed out and started a fire but this was a huge surge (actually called a fault because it was caused by 60k touching the 12 kv line) another fault caused a whole house protector to...

I just discovered new way to kill a Teensy. However they are so tough, the damage was only partial. So I have a question or two about the likely damage and whether I should even consider keeping the damaged Teensy for an emergency backup. I have a Teensy 3.2 running my gin still. It measures...

i just thought it might be a known issue like the problem with the program button and the win 10 update. i understand that this program requires a lot of stuff that one would not have around and that it would take a lot of time to try to reproduce etc etc. if use midi plus serial i get better...

if i use serial + midi instead of just serial the program works. i have had it running for hours after making this change. there is some mighty strange stuff in win 10. i should keep a separate computer for arduino stuff and stick to what works. i modified my control box so i can easily take...

I was able to upload files without using the button after updating to the latest beta teensyduino. The first program I uploaded with the new teensyduino would run for a couple of minutes and then freeze. So I added a bunch of serial print statements to try to narrow it down. Without all the...

remote program button That fixed it. I did not see this listed when i searched. I thought about updating teensyduino but had done so recently and did not think there was a fix for a very new windows update yet. It is the "Creator Update" that got installed. No idea why Microsoft was so hot on...

i installed a remote button and it works but i would still like to get the automatic programming working the way it was before updating windows. any ideas where to look for what might be preventing automatic mode? i already tried turning off the firewall.

thanks, i managed to miss that on the chart. i am used to looking at the long rows of pins and never thought of looking at the end :) hopefully the windows upade problem will sort out b ut at least in can remotely program my teensy without a plunger

Just had a thought. I bet this is some sort of stupid protection that windows is providing. It won't let the IDE communicate with the teensy through the USB port now for some reason only microsoft would know. I tried turning off the firewall but that did not make any difference.

This afternoon I programmed my teensy 3.2 as always. I am running win 10 on a notebook computer because i need to be able to take it out to the shop where my Teensy controlled still lives. I am using the Arduino IDE (which i am not thrilled with) because i am lazy and do not want to learn...
