ESP32-S3 with USB Host, Max Packet Size 524>512

Hello fellow ESP developers,

I'm working on reading data from an isochronous device, the InfiRay TS2+ thermal camera.
The camera uses a Max Packet Size (MPS) of 524 bytes instead of the maximum 512 bytes, leaving us 12 bytes short in the buffer.
This seems to consist of a 12-byte UVC header plus ...

Re: ESP32-S3 USB OTG - USB Hub support?


2. Small Receive FIFO - 512 bytes: 512 bytes is borderline enough for one streaming (high-bandwidth) FullSpeed device. It will not be possible to stream from 2 USB camera at the same time on S2/3 (at reasonable definition of the video).



I am trying to read data from a isochronous device, the ...

Re: Does "Flash Download Tool" support firmware loading via half-duplex UART communication ?

Hello,

I am currently evaluating, if it is possible to pass the UART stream through a CAN PHY .
There is no result yet, but some concerns and I need to dig deeper.

There are two main concerns i have:

1. the "TxD permanent dominant" protection of the CAN PHY, which will kick in after ~1ms tx-low ...

Re: ESP32, A2DP source, AVRC target

Meanwhile I spent a day, going down that rabbit hole.

One thing I missed, was enabling commands via
esp_avrc_tg_set_psth_cmd_filter(ESP_AVRC_PSTH_FILTER_SUPPORTED_CMD, &cmd_set)
however this only enables forwarding the command messages from the bluedriod stack to the application.

For the ...

ESP32, A2DP source, AVRC target

Hello,

I tried to implement a "media player" device that acts like a mobile phone would in modern car MMIs.
To my understanding this means, it provides an A2DP source and is controllable via AVRC.
There are examples in the ESP-ADF which implement part of it, but this scenario seems not supported ...
