no one ?

No one have some suggestion ?

@ESP_Sprite,

Do you have some suggestion ?

Thank's.

Hi,

Is there some examples or step by step to integrate communication between esp32-s3 and alexa echo dot ?

I read something about belkin wemo emulator for local communication only.

Notes:
× using esp-idf, not arduino.
× profissional application.

Thank's.

@ESP_Sprite, I decided to replace a flag with a binary semaphore, ie: xSemaphoreCreateBinary(), to guard GDMA busy channel. When i used the flag(the flag was released on dma end of transfer interrupt), sometimes the flag was not released, and task locked on not released flag, triggered the watchdog ...

Hi @ESP_Sprite,

With ecc disabled on psram i reach 20 MHz on lcd bus.

I don't know if all the transmitted information is correct, but the packet transmission time is correct.

I'm sure we have or will have some docs online for that at some point, I seem to remember a colleague was working on them, but the skinny of it is that PSRAM access is roughly divided 50%/25%/25% between DMA, CPU0 and CPU using a round-robin arbiter (so the percentages of the others can grow if one...

Hi @ESP_Sprite,

I enabled ecc on psram.

Will it influence in some way ?

Thank's.

Are you sure you're not running into a bandwith problem? It seems like the LCD PSRAM stuff is pretty sensitive to bandwidth starvation and doesn't really handle it well. I decremented the lcd bus frequency to 15 MHz and it worked with the server enabled. I don't know if this frequency is stable, i ...
