teensy

I'm working on a circuit for audio output from a Teensy 4.1 using as PCM5100 I2S DAC and a TPA6111 amp. I'm wondering if the circuit, specifically the headphone out (circuitry around U23) looks viable. I want the headphone output to be able to drive both low and high impedance headphones...

Sometimes it’s hard to know where to start with getting devices working on a new platform, like I2C keypads, sensors and screens: here’s a writeup that provides some sample code to nicely interface plug-n-play SparkFun devices with a custom OS (NetBurner’s RTOS) with minimal reimplementation...

[EDITED BY MODERATOR MOVING THE FIGURES TO THE BOTTOM WHERE THEY SEEMED TO BELONG ACCORDING TO THE TEXT] Hello everyone, I’ve developed a board that allows levitating a magnet using a feedback control system. It’s powered by a 12V jack and controlled by a Teensy 4.1 microcontroller. Everything...

Hello everyone, I am looking for a microcontroller to replace a Teensy 4.0. The problem is that the Teensy doesn't cope well with high temperatures. The specifications I'm looking for are as follows: - High maximum operating temperature, at least 125 degrees Celsius - Minimum 13-bit...

Hi, I have an MST342C02 stepper motor (200 step/rev and 4 phases) with SMD42C2 Driver. I have a converter which gives 48VDC 12.5A from 110VAC. I have Teensy 4.1 as the microcontroller and using Accelstepper library. The motor is connected Bipolar Parallel. Some of the specs are as follows...

Hi, I was working on a thesis project on a portable ECG device, I checked these CIRCUIT: https://raw.githubusercontent.com/gaodingpan/ECG-on-Teensy/master/CSE_EE%20474%20Lab%206_%20Analog%20Front%20End%20for%20an%20Electrocardiograph.jpg VIDEO...

Hi, I need some help here if at all possible. I'm no electrical genius, and just having some fun. My little project is just not working. The schematic attached is using the AL3201 Reverb IC. The idea is to attach it to 2 modules, the CJMCU PCM1802 (ADC) and the CJMCU-4344 (DAC). I believe I...
