    50Hz Noise on Microphone input (Teensy 3.2 + Audio Adapter + Amplifier)

    Hello Guys! We're busy with a project including audio and recording, we are using the Teensy 3.2 and the Audio Board with a 20W amplifier. We are using the microphone input (not de line in). to record voices. The microphone we use is a Electret Microphone from Adafruit, also we can connect...

    Teensy 3.1 in combination with Digital & Analog Accelerometer

    Hi there! I've started a new hobby project where I want to test different kind of accelerometers in combination with my teensy 3.1. Now i've seen lots of guides of how to select a suitable accelerometer. But i'm getting stuck on the sensitivity part. I see different kind of notations, such...

    Teensy 3.1: Low, High and/or Band-Pass Filters

    Hi there! While I was measuring with noisy ECG signals, I need something that take cares of filtering the measured signals. I came across the following filter library: http://jeroendoggen.github.io/Arduino-signal-filtering-library/ It seems pretty easy to create a filter with this... It sounds...

    Teensy 3.1: ADC Measurement, SD logging, problem with Sample Rate?

    Hello! I've been busy with measuring analog values. It's possible to measure the values, but somehow i don't know how to increase the sample rate, it's maybe a noob question, but i'm using a combination of the following libraries - SDfat (for logging to SDcard) - RTC - Teensy Synchronous...

    Teensy 3.1: Interference between SDwrite and I2C?

    While i'm busy with my project for measuring ECG signals, there are some issues which came across. I've managed to write 2 analog signals synchronous to the sdcard. But at this very moment: a) I'm using an usb-to-I2C adapter which is connected to my Teensy and digital potentiometer...

    Teensy 3.1: LabVIEW + Controlling Teensy Outputs(I²C/Serial)

    Hi There! I've been trying to connect my Teensy 3.1 to LabVIEW. Using the tool "Basic Serial Write and Read Modified.vi" in this post: https://decibel.ni.com/content/message/69017. But I was wondering if it's actually possible to control the Teensy's I²C or serial output? Or do i need to use a...

    Teensy 3.1: 5V Output (USB) & Negative Voltage Input (ADC)

    Hi there, I've been watching the schematics and specification/datasheet from the Teensy 3.1, and I have two questions about the voltage output and ADC Input Q1 The USB input gives a 5V Out, I figured out that there is a 5V output line.. actually two, but one out(VIN) can be used for external...

    Teensy 3.1 ADC LayOut

    Teensy 3.1: ADC PINS / 16-Bits mode Hi there, Maybe a dumb question, i've been watching this pin layout from the Teensy 3.1 (see link) http://www.pjrc.com/teensy/card5a_rev5.pdf In the datasheet of the processor are the pins located on pin 9 and 10 (PGA0_DM/ADC0_DM0/ADC1_DM3 (9) and...
