You can watch the wiring and build video (here)[https://youtu.be/VVGln_-XEgI].
The circuit board schematic and PCB layout are available here
This project demonstrates how to use the ESP32 with the ICS-43434 break out board.
You can buy the board on both ebay and Tindie:
- eBay: https://www.ebay.co.uk/itm/154115095985
- Tindie: coming soon
There are two projects in this repository: i2s_sampling and server.
This is a simple node server that writes the samples received from the ESP32 to a file.
This project demonstrates how to use the I2S peripheral for high-speed sampling using DMA to transfer samples directly to RAM.
The current set of pin assignment in the code are:
| Function | GPIO Pin | Notes |
|---|---|---|
| bck_io_num | GPIO_NUM_5 | I2S - Serial clock |
| ws_io_num | GPIO_NUM_19 | I2S - LRCLK - left right clock |
| data_in_num | GPIO_NUM_18 | I2S - Serial data |
