Some webpages (ex: https://en.wireless-tag.com/article-item-75.html ) have started to show a nice full featured devkit for the ESP32-P4. 1. Is there already any roadmap when these will be available to buy for teams with smaller projects (100 - 1000 units per run)? 2. Will there be more basic devkits...

For low latency reasons we use the I2S module direct without the driver to output a PDM single channel signal. After figuring out how the clock needs to be configured it works great. But we noticed that the i2s_struct.h has more pdm related register values than we could find in the technical referec...

Hello Baldhead, i really really need your help ;-) Actually i have a ESP32 and im sending 24Bit data parallel with I2S. But the ESP32 has not enough pins and not enough space for my data. Now i bought a ESP32S3 because of more pins and more space. I thougt i can use it out of the box, but there are...

The sample already calls an interrupt when a frame is finished: i2s_int_hdl. This is done for each dma descriptor where the eof flag is set. To stop it from sending continuously you need to break the ring of dma descriptors. this rring is configured in lines 208 to 212. As you can see there the last...

Thank you for clarifying this for me.

I am a little bit confused about the state of dedicated GPIO on the ESP32-S3 Based on the idf documentation it is supported: https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/dedic_gpio.html But the technical references https://www.espressif.com/sites/default/fi...

For an upcoming project I am looking into options to send data from the ESP to an external device. The catch is that the clock (~1.5MHz) is generate external, too. As the reference manual is not completed yet I was checking the datasheet. I might have missed something but the only peripheral that ca...

As my use case requires this part of the code to run on a bare metal core I am looking for the low level interface for the Dedicated GPIO. The technical reference already has the chapter but it's still empty. Any idea when it will become available?

I am currently trying to decide if I should wait for the new ESP32-S3 for one more more upcoming projects or looking for something else. Beside of the higher number of I/O pins compared to the current ESP32 I would need some improvements when it comes to the read/write latency. I assume that the ESP...
