    Issues with I2S in slave mode and configuring ADS127L01 with Teensy 4.1 for audio processing

    Hello everyone, For test, I have configured the ADS127L01 in TDM (frame-sync) mode and I am using the Audio Library with AudioInputI2S to capture data on the Teensy 4.1. I am already receiving data, but it seems that I am only getting the 16 most significant bits, instead of the full 24-bit...

    Issues with I2S in slave mode and configuring ADS127L01 with Teensy 4.1 for audio processing

    Hello everyone, I am trying to use the Audio.h library on the Teensy 4.1 with the I2S interface in slave mode to receive audio data from an ADS127L01 (an instrumentation ADC). The code works well with the ADS127L01 configured in SPI mode, but I am looking for a solution to use I2S and take...

    Teensy 4.1 with ESP32 (AirLift): Very Low Wi-Fi Transfer Speeds

    Thanks for your question, Shawn! I’m actually working on this as well, though programming isn’t exactly my strongest skill. Since I need the Teensy’s native ENET interface for my project but also want a high-quality WiFi connection in parallel, I’ve been trying to adapt the QNEthernet driver to...

    Teensy 4.1 with ESP32 (AirLift): Very Low Wi-Fi Transfer Speeds

    Hello Angelo, Thank you for pointing that out! The default SPI bitrate for the WiFiNINA library is set to 8 MHz in the spiSlaveSelect() function of the spi_drv.cpp file. Here's the relevant snippet: WIFININA_SPIWIFI->beginTransaction(SPISettings(8000000, MSBFIRST, SPI_MODE0)); I tried...

    Teensy 4.1 with ESP32 (AirLift): Very Low Wi-Fi Transfer Speeds

    Hello Shawn, Sorry about the formatting of my post. I'm new to the forum and to the Teensy world, but I'm really excited about including the Teensy 4.1 in my new project. My goal is to acquire data via a multi-channel ADC, store it on an SD card, and then remotely download the data over Wi-Fi...

    Teensy 4.1 alternate Ethernet pins?

    Hello everyone, I saw this post, and it made me think about something that has been puzzling me. Is it possible to use the ENET2 on the Teensy 4.1 with another RMII transceiver to create a second Ethernet connection? I have checked the physical pins, and they seem to be available, but I'm...
