General Discussion / MicroSD fails to initialize

« on: July 21, 2022, 03:40:42 PM »

Hello! I'm having some trouble with reading an SD card. I have a TinyZero with a MicroSD TinyShield on top. I got my SD card here: https://tinycircuits.com/products/microsd-card-and-adapter-8gb. I'm following the tutorial here: https://learn.tinycircuits.com/Memory/MicroSD_TinyShield_Tutorial/. I've formatted the SD card using the prescribed SD formatter (FAT32), and I downloaded the zip that contains the CardInfo sketch that uses chipSelect = 10 and uses SerialUSB. Unfortunately, when run the SD card fails to initialize, and it outputs:

Initializing SD card...initialization failed. Things to check:
* is a card inserted?
* is your wiring correct?
* did you change the chipSelect pin to match your shield or module?

I've scoured the internet in an attempt to find a solution, but nothing I've tried has worked.

Any advice would be great!

General Discussion / No output from microphone Wireling

« on: July 20, 2022, 09:12:46 AM »

Hi! I'm having a bit of trouble that I'm hoping someone can help me out with. I have a TinyZero with a Wireling adapter connected, then I have a Wireling microphone connected to port 0 of the adapter. I've compiled and uploaded the example code found here https://github.com/TinyCircuits/TinyCircuits-Wireling-Microphone-AST1030/blob/master/examples/Microphone_Wireling_example/Microphone_Wireling_example.ino.

Here's an image of the connected boards: https://ibb.co/X4GFnVD.

My issue is that it seems that the microphone is not detecting sound. When I open the serial plotter, I see this: https://ibb.co/7kqp3Fq. It doesn't change when I clap, or try to make any other noises.

When I change the pin to check the other three ports I see: https://ibb.co/FJktSX3. Again, no change with noise.

When I change the pin to a non-existent port, A4, I see: https://ibb.co/qgg2cZq. Again, no change with noise.

I've tried connecting the microphone to different ports and that didn't help.

I can't tell if the microphone is broken, or if I'm missing something silly. Any help would be great!
