The use of the ESP8266 in the world of IoT

#96419 I have a 2.8 inch TFT display hooked up to ESP8266 over SPI. The goal is to make the display show a QR code image (back-and-white, 220x220 pixels) received from a PC via USB. The image HEX file is around 400-500 KB. Is ESP8266 capable of receiving this amount of data at once or should some "portioning" be implemented to achieve this?

I'm a bit confused: 220 by 220 pixels would only take 48.400 bits (a bit shy of 50kB): there must be a more optimal way to reduce your data.
You could even just let your ESP generate the QR code on its own.
