I sent an update last night but it is not posted so will summarize what i learned again and thanks for the support. I was reluctant to try some things and have learned a lot from the experience. First, I should have used the esptool.py -p COMX flash_id command line. It shows that the WROOM2 used 32M...

Tried the EFUSE command: espefuse.py -p /dev/<serial_device> --do-not-confirm burn_efuse FLASH_TYPE 1 That has resulted in a new problem. I now get the following MD5 fatal crash. Am I totally dead now with this board? Changing the connection cord did not help. FYI - Using the i2saudio demo example a...

I have built an internet radio application that currently runs on Arduino IDE with a ESP32-S3-WROOM2 Dev Board using the audo.h i2s routine, WIFI, and IR remote. I recently purchased some less costly Dev Boards that have ESP32-S3-WROOM1 and 16Mb Mem and 8 Ram. For the Wroom2 board I programmed with ...

I guess I should mention I found 266 examples of stethoscope codes on github. About 10 percent of those examples use the ESP32 microcontroller. Examples include Wifi and Bluetooth, but I did not find any that add a second microphone for ambient background correction. There were some that used severa...

I am evaluating a ESP32-S3-DevKitC-1 with INMP441 [or other MEMS microphone] for a stethoscope application. The microphone is using the left channel. That is working. I now want to add a second microphone of same type and lot to monitor ambient background using the right channel. I am not sure of th...
