the Arduino will just read the next place in the memory, without realizing that the value it's reading isn't a part of the array anymore. It will just give you the value it finds at that particular spot in its memory.
*E.g. #define LV_FONT_CUSTOM_DECLARE LV_FONT_DECLARE(my_font_1) LV_FONT_DECLARE(my_font_2)*/#define LV_FONT_CUSTOM_DECLARE/*始终设置一个默认字体*/#define LV_FONT_DEFAULT&lv_font_montserrat_14/*启用处理大字体或包含大量字符的字体。 *这个限制取决于字体大小、字体类型和 bpp。 *如果某个...
for example to embbed RGB APA106 LEDs with GRB WS2812B or RGWB SK6812 LEDs. This is useful to use LEDs that come with different physical properties and formats, for art projects. Just declare multiple LED strip objects on the same port, and use the one matching your LED strip model at...

It provides a Matrix class which can be used to declare 2D matrices of arbitrary height, width, type and even storage policy (see below). The matrix overrides the +, +=, -, -=, *, *= and = operators so they can be used naturally in algebraic expressions. It also supports a few ...

First, we declare a function that provides a clock signal to the ST_CP pin of the 74HC595 shift register. This clock_signal() function generates a clock signal with a time period of 1ms or a frequency of 1KHz. Because on-time is 500 microseconds and off-time is also 500 microseconds. ...
