Hello, I have a remote machine which runs on ubuntu 22.04, has ros iron and I want to install micro ros iron library to establish communication between ros and microcontroller. In order to do that, I installed arduino IDE 2.3.2, teensy is automatically installed when the board is installed using...

Hello Srinivasan, How did you install 1.57.2, I tried to do that from the board manager but it doesn't compile reporting that it needs a precompile helper function. When I try to install the latest version it says, Compilation error: fork/exec...

Hello all, I am trying to make my arduino mega communicate with my teensy 4.1 through wire1 and lcd print the output. I am using Pins 20 and 21 from arduino mega to Pins 16 and 17 in teensy. Since it is 5v, I pulled up two 1k resistors from 3.3v to the pins 16 and 17. The pins 18 and 19 are used...

I wanted to check if the current that flows to the RX pin of Teensy is within range. Am I wrong? Just to be safe I wanted to check the current and voltage supplied through the tx pin. If the current is high I thought of putting a resistor in series before connecting to teensy gpio. Please let me...

The yellow wire is the common ground and tx is the blue wire (Fourth pin from the right as shown in the picture). It keeps changing from 25 to 30 or 35 mA.

I tried the same but the bluetooth did not power up. It's the same model and they have mentioned that the voltage range for the input is 3.6v to 6v. The output is gonna be around 3.3v. I was able to power up using 5v and gnd. However I am scared that my current would be too much for the gpio...

Great insight, thanks. I'll proceed with this tonight and let you know how my control tuning goes. I hope I don't burn my teensy this time. I actually was new to the forum and haven't asked any kind of questions before. I remember that I mentioned the model number in my second reply. However I'm...

Connection: 5v Pullup: 3.3V Pullup: No Pullup: These experiments completely make sense now. The problem was due to the current that sunk into my gpio pins. The current measured with no pullup was the highest which was around 15mA in 15 readings and with a 1k Pullup resistors it did not...

Thank you for the insight. I actually forgot to mention something. I used another Teensy 4.1 and I just connected my encoder outputs directly to the interrupt pins of the Teensy as I was not really aware of this before. I did that because it seemed to work well with Arduino. I ended up burning...

Hi, I took a look at the working principle of the entire thing we discussed yesterday. However I don't understand one thing. To my knowledge, I understood that the phase signals' outputs that come out of the encoder's receiver is connected to the base of the npn transistor and the pullup...

Okay sure :)

Okay, thank you very much. I will come back if I face any issue.

https://forum.pjrc.com/threads/70595-5v-encoder-(600PPR)-for-JOGWHEEL I think this thread should work. The part number can be seen from the attachment in this message (c38s6g5-600b-g24n). Since, its not produced a very renowned manufacturer, I dont know if the datasheet is accurate. However I...

I just recently began using Teensy, and I'm happy to say that I'm a Teensy 4.1 user. However, I am having a lot of problems, which I am gradually resolving with the assistance of the knowledgeable experts present in the forum. All of you are appreciated. In order to explore the terrain, I'm...
