Video animation with ESP32 - example

Postby Deouss » Thu Aug 02, 2018 1:59 am

I have created code transmitting a live captured image from desktop PC to TFT (320x240) over WiFi at quite reasonable rate.
Link to video here:
ESP32 Animation Attempt

Windows side code is WPF C#.NET 4.6 and ESP is FreeRTOS idf.
I wonder if anyone experimented with how fast data can be transferred to TFT and how large screen can be.
This example runs with SPI 60MHz native pins.

I will post all code when I have time if anyone is interested.

How the hell did you pull this off?

Code: Select all

task_t coffeeTask()
{
	while(atWork){
		if(!xStreamBufferIsEmpty(mug)){
			coffeeDrink(mug);
		} else {
			xTaskCreate(sBrew, "brew", 9000, &mug, 1, NULL);
			xSemaphoreTake(sCoffeeRdy, portMAX_DELAY);
		}
	}
	vTaskDelete(NULL);
}

It's a simple socket transmission - but it is constant streaming without closing socket. Fast isn't it? )
It actually runs so smooth I couldn't believe - this is not psram.
I will test the speed with SPI RAM memory on wrover.
With WiFi you can virtually do anything. You can create nice Windows app that will fully control ESP- remotely!
I'm intending to test Lora and non-tcp protocols too.
