Hi ,

I am working with the ESP32-P4 PARLIO peripheral, while i face an issue with not receiving memory used data in cb i also now am running into an edge case regarding callbacks when mixing loop and single-shot transmissions.

The Issue:
If I start a transmission in "loop mode" and later try to ...

Thanks for validating that! I completely agree—having it mirror the design of on_buffer_switched would make the API much more robust for asynchronous queueing and better handling when the buffer is used .
Parallel io is really a nice addition hope it evolves a bit more with multiple units of tx and rx

Thank you for the clarification! It makes sense regarding forward-compatibility and API consistency. It is good to know it is by design and not a bug or pending in implementation (Hopefully).

To answer your question: I was expecting the struct to contain the memory address of the buffer that just ...

Hi everyone,

I am working with the ESP32-P4 and using the PARLIO (Parallel IO) peripheral for transmission. I am trying to transmit multiple buffers consecutively, but I am running into an issue with the callback event data.

I have registered the following TX done callback:

C
static bool IRAM ...

Further inspecting the schematic on the power side, the power handling magic is now satisfactory clear :lol:

the usb C (programmer/debugger) is given priority and USB A can also power if USB C is not powered .. the power logic is sperate from USB mode logic ..

I just hope USB device is easily ...

hey,
I am just curious ..
do you intend to take video at 200Hz ?
What is the resolution ?
and where and how is it going to be stored or streamed ?

hi tore-espressif
Thank you for your suggestion :) ,
this also gave me a start point

I see H3(usb host/device selector) runs a FSUSB42UMX (USB MUX),
1) when H3 is in host mode ...

I have not tried but as per the specs for wroom2 it uses Octal SPI for PSRAM
What I know based on my own endowers is that you can look for Oct SPI RAM from vendors like APMemory or Winbond
Or just look for APS6408L or APS12808L series from these vendors

Hope it helps
