arduino ide 1.8.9无法编译arduino gfx例程 也无法编译rgb565 video例程。 我很喜欢vide例子。

[moononournation]

what is the error?

为开发板 ESP32 Dev Module 编译时出错。

[moononournation]

The error message is ad-normal, e.g. Arduino_TFT.cpp:651:127: error: operation on 'offset' may be undefined [-Werror=sequence-point] But line 646 already declared: uint32_t offset = 0;

I am using Arduino IDE 1.8.13 and everything runs well. Please try to download latest Arduino IDE, latest stable Arduino-ESP32 and latest Arduino_GFX. And then try again.

你好，可否给出RGB565 video hex固件？

[moononournation]

RGB565 video sample code just in demo purpose, you should add your own logic before you can really use it. So first of all, please clean up your computer and install latest software to make it compile success.
