Just scroll down to Arduino 1.8.x Software Development on this page, then select your operating system. The Teensyduino for .Arduino 1.8.x will download. Once you have installed your Arduino 1.8.x (and I find that you have to execute it just...

The Teensy 3.3V output will be able to drive the MAX485 but the MAX495 output voltage(to the Teensy) at 5V will be too high and will probably damage the Teensy. If not immediately then will lead to future degradation and damage. You will need a...

When you post code can you post it between code tags using the </> button. It makes the code readable for someone who is not familiar with it. See code below. The code shown above, and below, does NOT compile. #include <FlexCAN_T4.h>...

Do you have something like this while (!Serial); in your code (in setup)? If you do, when the USB is NOT plugged in, it will wait there forever, waiting for the USB to appear. If that is the case change your setup code to something like below...

Please post any code between code tags using the </> button. It makes your code much easier to read and understand. I have posted your code below so that you can see the difference. /* OctoWS2811 VideoDisplay.ino - Video on LEDs, from a PC, Mac...

As @defragster reported and BitDefender still complains vociferously!.

Have a look here. Isn't google great.

Still Getting this and all the keep stuff etc.

No, byte is 8 bits wide, uint16_t is 16 bits wide.

Windows10 Pro and whatever Explorer calls itself today. BitDefender did not like it. ....and following Windows thought:-

I suspect that the Teensy watchdogs are separate from the processing unit so might not suffer from Teensy lock up. They would be pretty useless if they did. If you are concerned then use an external watchdog chip/device. You have a Hazard...

Have a look at the Snooze library.

On Teensy pin 0 is RX and pin 1 is TX. If you have them wired as you state above you have RX going to RX and TX going to TX. RX should go to TX and TX should go to RX.

....then could we see your wiring?

On Teensy 4.0 the ADC always uses the 3.3V power as its reference. That's hard-wired inside the chip (why NXP did this I can not say) so you always get 3.3V reference no matter what you do in software.

The problem files are contained within the AMY-Arduino.h Additive Music synthesizer library and the files it pulls in. The library is here. Even the supposedly tested Teensy example program from examples fails to compile. I suggest you contact...

Do you have something like this below in your code? while (!Serial); If so it will wait forever if NOT connected to the IDE, If so try putting the code below in instead. while (!Serial && (millis() < 3000));

I can confirm that the latter is the case for me as well.

That post was to show how to be able to (cheaply) remotely control mains (240V in UK 110V elsewhere) voltage from a Teensy. The project is still ongoing, which is intended to have whole house control of central heating down to individual...

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.

Make sure to use some Schottky diodes.

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:

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.

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.

Double posting doesn't really help. It just annoys people and clogs the forum.

Please post code (using </> button) and details about which Arduino IDE and what Teensy board. Without this info it's not really possible to be too helpful.

Pin 13

#if defined(__IMXRT1062__) // Teensy 4.0 & 4.1 clear Uart Buffer _stream->read(); //Serial.println(_stream->read(),HEX); #endif A byte is thrown away at lines 462..465. Might be the reason. Uncomment the...

When entering data press the </> button on the entry screen and post your code in the resulting form that opens.

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...

In future when you insert code can you place it between code tags using the </> button. It makes it much easier to read. I have put your code between code tags below. #include <Arduino.h> #include <SD.h> #include <SPI.h> #include <cassert> File...

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...

Have a look at this.

Could be pull up resistors.

Not any more it would seem.

Agreed.

Still can't repeat the problem(s) of yesterday, perhaps treat it as a computer aberration....though it WAS rock solid on 1.59b4....and so far back on 1.59b6 still is.

I had switched to 1.59b4 last night and it was rock solid no problems. Just switched back to 1.59b6 and so far (1/2 hr) been unable to repeat the problem.

I am experiencing problems uploading to a T3.5 (Teensyduino 1.59b6). The Com port has started to disappear and the Teensyduino uploader is unable to find the Teensy whether set to COM or COM(Teense 3.5)Serial.... The only solution is to re-boot...

It's dependant upon the hardware making up the Processor/Processor Chipset on your PC and their appropriate drivers.

With file explorer open (or whatever it's called) click view at the top left of the explorer window, then click (select) Hidden Items towards the right of the Menu Ribbon

Just improved the batch file, this will work for any current user: del /F /S /Q C:\Users\%username%\AppData\Local\Temp\*.* pause

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...

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...

"Basic.ino" compiles for me when compile type set to MIDI, Serial + MIDI and Serial + MIDI + Audio.

That would make eminent sense.

What value pull up resistors are you using? Can we see your code.

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...

Serial Comms, that's the way I would go. Using Serial comms. gives you buffered communications, mind you that can be problematic if the two systems get out of synch. Below is some code that I use to get data from an ESP32C3...it includes code to...

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...
