    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    You will find that the ESP32 devices supporting two USB ports as you require are usually built like shown in the pic below:- see this.

    100 +/- inputs and outputs (analog?)

    You could consider using an ATtiny 212, one for each channel. They have A/D and D/A. At $0.43 they are cheap enough to allow 1 per each of the 100 channels. See article below:

    100 +/- inputs and outputs (analog?)

    Hi Gef, Can I suggest that you split your text into paragraphs as I have shown below. Like using the </> button when placing code into a post, it makes what you are saying more manageable to read. Best of luck with your project.

    Teensyduino 1.59 Released

    If you set your USB to Keyboard+Mouse+Joystick it compiles just fine. Without "Joystick" as one of the USB settings it wil, fail to compile.

    Teensy 4, Interrupt is blocking USB Sketch Upload

    That is not a complete .INO file. You need to write a complete ino file for Arduino/Teensyduino to compile and upload to a Teensy. What is being programmed into the Teensy by pressing the Program button (it's NOT A TEENSY RESET BUTTON) is the last file successfully compiled.

    SPI communication between Teensy 4.1 and arduino nano HELP!!!

    It helps if you put your code between code tags using the </> button. See below. Your initial post said hat you were setting the Teensy as a Slave but you have not used the SPI_MSTransfer_T4.h library as mentioned above. It would be useful if you could turn on verbose output for compile. This...

    Cannot compile with USBHost_t36.h [solved]

    You could try emptying your "temp" directory, often times part compiled code is stored there. It's supposed to save time by not having to re-compile everything when a change is made to your code. I have put together a batch file to do the work for me, here is a copy below, juts change "bob" for...

    I2C startup issue

    Sometimes the Teensy is SO FAST that it starts communicating with external ICs before they are ready. Perhaps put a delay of a second or so in SetUp. By the way it makes your code much easier to read if you enclose it between CODE tags using the </> button. You see it makes a world of...

    Adding Bluetooth and WiFi to a Teensy 4.1

    Normally serial does not need a CS pin, the receiving device looks for any characters received i.e. if (Serial.available()) ... then do something, however there is nothing to stop you using an IO pin as a CS pin in which case the code becomes if (digitalREad(CSPin)==HIGH) ... do something

    Adding Bluetooth and WiFi to a Teensy 4.1

    I use JLCPCB, I normally can expect to receive boards which include assembly in a week using Fedex. They have a minimum board count of 5. Incidentally any size up to 10cm X 10cm is the same price, so if your board is less than 10x10 you could squeeze another design on the same substrate and it...

    Odd sized screen - just can't find an option

    I think I might have a solution for you. Cut slots along the long edge as shown in the picture below. This will allow a Nextion 2.8" display to be sunk into the slots. I believe the edges of the display will not show outside the slots, though that will depend on the wall thickness of your...

    Have I broke my teensy 4.1 board ?

    I normally solder at 400C, that way I don't need to keep iron on component for long. Lower temp means that iron contact is for longer giving more time for heat to travel to other board components.

    The Nextion display is only 1mm wider than the hole size, so you could place a panel on/in the enclosure which would allow the Nextion to be mounted on top. Given that the Nextion is only 1/2mm taller (wider?!) than the hole it should not encroach outside the outside dimensions of the enclosure...

    Arduino 2 - serial port disappears

    That would suggest that the problem is with your software. You could start adding software back until the problem re-appears OR Remove (or isolate) software from your original code until the problem goes away--the last removed would likely be the problem area.
