This is a supplement to my speed comparison of STM32 and Arduino boards. Watch it here: Details: - 2.2" LCD display based on ILI9341 driver - resolution 320x240, 16-bit RGB, 24-bit calculated - 1 pass only, no antialiasing (to avoid long boring video) - ESP8266 configured in both 80 and 160 MHz Conclusions: - ESP @ 80MHz is little slower than cheap STM32 @ 72MHz - but @ 160MHz is way faster! - ESP&SPI speed is not as impressive as STM32 Source code:
