Hi all,
I have an SD card module that works only with an Arduino Nano, I've tried connecting it with the Teensy but for some reason, it won't work, but it works well with the Nano. Is there a way to send the data collected on the teensy with the sensors to the Arduino Nano which can store it in the SD card module?
it's possible to communicate with the Nano (Serial, I2C, SPI) but you should really fix the root cause of the SD not working.
Which SD module? Please provide a wiring diagram how the SD module is connected to the Teensy (photo of pencil/paper drawing is fine).
Yes; however be aware that the Nano is a 5V device and most Teensies are 3.3V devices.
This is the schematic and the blog I followed. I'm using the micro SD card reader module with a 16gb micro SD card.
Thanks for the replies!
I'm honestly just a beginner to coding, I'm making an altimeter for a project where I'm implementing a Kalman filter and a complementary filter for values from a barometer and an accelerometer. Upon testing them individually, the Teensy seems to be performing better which is why I was thinking of ways to send all the data to Nano which does the datalogging.
Thank you!
does your module expects 3.3V or 5V ?
Mine uses 5v
can you share a good, in focus, picture of your wiring ? did you solder pins?
I'm using a breadboard for the connections.
I uploaded the CardInfo code under examples from the SD library and this is the output I got.
which Teensy version do you have ?
can you try using the GND pin that is labeled as such at the opposite of the 5V pin across the board instead of possibly the A-GND pin?
GND is for digital returns (I2C, I2S, SPI, GPIO, etc) while A-GND' is the zero equipotential for any analog input. Don't mix those.
I doubt that's true. It will probably work with any 5V arduino.
The Teensy 4.0 is a 3.3V device.
Probably. If you want to make it even more of a challenge, try wiring it up wearing boxing gloves.
You need a 3.3V SD card module. They are probably the same price or cheaper, and a little smaller, because they have fewer components.
