    Pyro channel circuit validation

    Hi, i am building an automated firework launcher with a teensy 4.0, and i wanted to use a mosfet as a switch for activating the ignitor of a firework. This is the circuit i came up with: I was particularly concerned about which mosfet to use since the digital pins of the teensy operate at 3V3...

    Teensy 4.0 I2C Bus issue (solved)

    BTW i think that i've found the problem. I've might connected the bmp280 with an inverted footprint from the breackout board. I will check and tell you.

    Teensy 4.0 I2C Bus issue (solved)

    Thank you for answering. I will try adding resistence between i2c and the 3.3 of the teensy. However i don't think that 5V will kill the board because on the website under the power tab it says that the teensy has a regulator connected to the VIN pin that lowers the input current to 3V3, thats...

    Teensy 4.0 I2C Bus issue (solved)

    Thank you for answering. I checked the datasheet of the breackout board i used for the mpu6050 and it sad that it has 4.7k resistors between both sda scl and vin. That's why i didn't addd them in the schematic.

    Teensy 4.0 I2C Bus issue (solved)

    Hi, i've connected a bounch of components to a teensy 4.0 according to this diagram (i know that on the sd card slot positive and ground are swapped, that was made according to the footprint of the breackout board i used): When i try to use the mpu6050 or the bmp280 i can't get a connection over...

    Teensy 4.1 - Arduino nano ESP32 Comunication

    Hy, i've setted an arduino nano ESP 32 to comunicate with an arduino cloud dashboard to send a message over serial to a teensy, but the teensy doesn't seam to receive it. Here's the arduino nano ESP 32 code: #include "thingProperties.h" int comando = 0; void setup() { // Initialize serial...

    Teensy 4.1 and Arduino nano 33 IOT

    Thanks everyone. I'll try to mesure the consumptions of the arduino and if it's too high i'll use an external breadboard power supply.

    Teensy 4.1 and Arduino nano 33 IOT

    Hey everyone, still me trying to get these board to comunicate. Now the problem is a bit different. When i plug in the arduino in the computer it works perfectly and it responds to the comands in the arduino cloud dashboard, but when i try to power it through the teensy the build int led blincs...

    Serial comunication between Teensy 4.1 and Arduino Nano 33 IOT

    Yes but that line is on the teensy code, the receiver, because i want to use one of the 8 hardware serial ports of that board and not the first one. As you can see in the picture the jumpers are connected to the serial 2 of the teensy

    Serial comunication between Teensy 4.1 and Arduino Nano 33 IOT

    Thanks a lot, i didn't know that on the arduino the serial monitor was separeted from the Uart. Now i see something on the serial monitor of the teensy but is random numbers that dont make sense. I checked that it was set to the same baud rate of the boards (9600) but it didn't change. I also...

    Serial comunication between Teensy 4.1 and Arduino Nano 33 IOT

    Hi, i am trying to get a teensy 4.1 to comunicate with an arduino nano 33 IOT over a serial bus but. Here is the arduino code that is supposed to constantly send a message: void setup() { Serial.begin(9600); pinMode(13,OUTPUT); digitalWrite(13,HIGH); } void loop() {...

    Yes, but now i need i2c

    Code debug

    The transmitter is always sending eatch time 1 component of the array channels by time. i thought that when the first has arrived to the receiver the others would be coming directly after that. In total it's passing all the 16 integers of the array

    Code debug

    Hi, I found a library that allows a teensy to comunicate with an sbus receiver. I need to pass the data received (an array of integers) to another board with I2C. I can see things happening on the board connected to the SBUS receiver but nothing on the board that's supposed to receive the array...

    Voltage regulator issue

    Hi, i built another board and now the voltage is stable but not quite at 5V. Its a little lower like 4.9V. Is it a problem for teensy, servoes and other boards(the say that the VIN should be 5V but pls tell me that 4.9 is good, i don't want to make another board)

    What happens if i plug more than 5V unto the VIN pin of teensy 4.0 and 4.1?

    Thanks. i knew that that were probably going to happen so i asked first in order to not having to spend more money

    Connect MPU6050 and BMP180

    Ok, but maiby i was not clear. I have understood that both sensors can run on the same bus but my question was because they can do that, what should i use the other I2C buses for?

    Connect MPU6050 and BMP180

    Hi, i need to conect both mpu6050 and bmp180 to an teensy 4.0 via I2C bus, but i do not know how to connect multiple i2c devices to the same board. How can i interface to the multiple I2C ports of the teensy? Luca.

    Problem with Teensy 4.1 and HC12 Comunication via SoftwareSerial library

    Thank you very mutch guys for your time and at this point i think that the problem with the second code that i shared was a brocken HC-12. the new one is on the way and if it works i will let you know. Luca

    Problem with Teensy 4.1 and HC12 Comunication via SoftwareSerial library

    I don't know why, but i think that one of the HC12 just brocke cause of a short circuit, (the chip and the power cables were so warm (the one connected to the teensy with a breadboard power suply)). I cant swear it was not broken already before tryin it out but i wil order some more radios and i...
