I am using a Teensy 4.1 and Audio Adapter on a test fixture design. I will be measuring audio signal level (with the Audio Adapter -> USB audio), as well as measuring logic levels and analog voltages with the 4.1. My question is, should I use...

I am wanting to use the 4.1 as an interface for both audio (in and out) and serial UART data (in and out). The device shows up on Windows as Com5 Which RX / TX pair do I use on the 4.1 for hardware UART interface? Where in the code is the Com...

So if the I2S is handling audio in and out and those are bussed to usb audio (in and out) I can reassign chip selects for the memory chip and SD?

When using the audio adapter with the 4.1, how many of the pins must be dedicated to the adapter interface? If the settings card is not used, can those pins be used for other purposes? What about the memory chip and volume control pins?

Is the USB micro connector the only way to connect the Teensy 4.1 to a host computer for a combination of USB audio and USB serial?

Probably would be a 4 layer board

I am planning to integrate a Teensy 4.1 and Audio adapter board in a test fixture project. Normally, the audio adapter pcb is mounted directly above (or below) the 4.1 on header pins. I want to be able to connect to audio line in and line out...

The code is coming for an Intel Hex file -> transmitted to the Teensy over USB serial connection -> then decoded and programmed to the SPI flash device. This is not a USB host application Just looking for sample code to erase and program blocks...

I am using a Teensy 4.1 as the "brains" of a product test fixture. I need to program the bootloader code for the target board into a W25X40cl flash device. The 4.1 will be interfacing with a Windows application to run the test sequence and will...
