What needs to be considered when connecting Teensy 4.0 to CMOS levels. Is a level shifter needed?
The CMOS devise gives specifications
CMOS 3.1V, High: min 2.7V, Low:Max 0.4V
If level sifter is needed, is there...
If it is not possible to have VENDOR_ID and PRODUCT_ID separately defined for MIDI and Serial, would it be possible to define them via name.c like MANUFACTURER_NAME and PRODUCT_NAME can be, how?
This is what I...
I tried, it did not work.
Anyway I think the problem just was that the Product and Vendor ID are not correct so Arduino IDE does not recognise the board.
It has been now working fine by just pressing the button...
So I made this simplified example of above and it works exactly as expected. On this one I have changed the case 0xB0: to case 0xA0: so that the default get executed and it does. But that is not the case with the above...
Hi,
It is not first time I am using Case structure, but having so weird problems that maybe I am just blind to my own mistakes. Never mind the other code the case structure is what is failing.
The problem is that...
This was long time a go, but have the same problem
trying to do with Teensy 4.1
usbMIDI.sendSysEx(SysExLength, USBhostMIDI.getSysExArray(), true);}
usbMIDI is the computer side of the connection and...
Ok, so maybe this is not what you are looking for, The button works, it is just Arduino IDE does not indicate the load was success.
But a question. For this case there is no need to change the VENDOR_ID and...
well it says
"The following errors occurred:
LaunchControlXL_V002.ino.TEENSY41.hex: Invalid File"
So here it is

No problem sharing that but I solved the problem before I came back here, and the button press worked anyway. I thought not needed and should be easy to reproduce just changing the
#elif defined(USB_MIDI_SERIAL)
...
A side question as related to editing the libraries.
The LaunchControl XL is a 12 Mbit/sec device, could this be the reason for remaining initialisation connection problems?
I found the
USB1_PORTSC1 |=...
After all pressing the program button worked, it just does not look like that on Arduino IDE
So when I changed usb_desc.h back to normal and pressed the button it loaded and after that works as normal.
Would be...
To add,
Arduino sees a serial port (generic port not teensy) and serial monitor works on it as it should, but when loading the sketch I get
"No Teensy boards were found on any USB ports of your computer.
Please...
Hi,
I am trying to make Teensy 4.1 look like LunchControl XL MIDI controller so that SD MixPre would accept it and connect.
Using name.c I got MIDI and Manufacturer name changed, but the MixPre did not recognise...
After a while I had time to look into this, now I have LaunchControl XL
First, the LaunchControl XL works great with the InputFunctions USB Host example. I.e all controls provide clear and what seems correct printout...
