    Problem connecting ADXL345 to TEENSY 2.0

    Hi Paul. An attempt to work through the I2C bus was also unsuccessful. Here is the connection diagram.

    Problem connecting ADXL345 to TEENSY 2.0

    This is a schematic diagram in PDF format. I think that the SPI port cannot be connected to other pins because the processor does not know them.

    Problem connecting ADXL345 to TEENSY 2.0

    Several projects with accelerometers for Arduino NANO and TEENSY 4.1 work well for me. All examples from the SparkFun_ADXL345 and Adafruit_ADXL345_U.h libraries work perfectly. But now there is a need to connect this accelerometer to Teensy2.0. Nothing works. The processor doesn't see it. The...

    3.3V backup regulator advice

    Good day. There are thousands of such implementations. It is important to know the power requirements of consumers and remember that it is not recommended to take more than 0.5 A from the port. Maximum ripple, Average and maximum current consumption, time diagram of approximate current...

    Teensy4.1 witch Ethernet for Blynk

    Good day everyone. First, I want to thank the support for the help. Now my previous project Datalogger receives information at a speed of 5 Mbps, processes and stores the data. That's great!!! Now a new challenge. I'm not a fan of ESP for reliability reasons. And I want to solve the following...

    Some problems with the SD card.

    I cannot understand the reason. After removing Arduino IDE and re-installing version 1.8.13. With the subsequent installation of Teensyduino 1.54. half of the libraries were missing, I had to install them manually, but some libraries stopped working. For example, the example of TimeTeensy3...

    Some problems with the SD card.

    Some problems with the SD card. I first purchased Teens 4.1 from you and tried to work with it. Deep respect for authors. That's great. In a short time, I solved the problem of creating a datalogger for an underground radar. There is a large stream on the serial port. About 200 kilobytes per...
