We just try to realize a project with an esp32-s3 platform to classify sound events. We are using the https://github.com/espressif/tflite-micro-esp-examples repo which working fine and compiles on idf master also using ai acceleration of the esp32-s3 However we need a framework for setting up and l...

I am using ESP32-S2 chip in my design. ESP32-S2 supports only two serial hardware channels. But I have three devices that needs serial communication. 1- USB to UART converter chip, 2- Coin dispenser device, 3- RPI serial communication. Can I use SPDT switch for selecting from two serial devices? Wi...

To get the MAC address of the gateway (router) when using eth connection with Espressif ESP-IDF framework for the ESP32, you can use the following code: #include "esp_system.h" #include "esp_netif.h" #include "esp_eth.h" #include "esp_log.h" #include "esp_netif_dhcpc.h" esp_eth_handle_t eth_handle =...

I want this to show up in the startup log, after the partition table info or thereabouts. I’m using PlatformIO and I don’t see how I can do this. Anyone know how? (I know how to put a version number in my own code and print it. That will show up much later that the startup log.) check the Custom bo...

Hi Rudi, It is possible to get the ISA reference manual (and the rest of the Xtensa SDK, in fact) from Cadence under NDA. A few of our customers did get access to the xt-xcc compiler from Cadence this way. You can contact Cadence directly (saying that you are developing a product based on the ESP32...
