Arduino应用开发——LCD显示图片 LCD是项目中比较常用的外设,基于Arduino开发有个好处就是它很多相关的库可用,这对于项目的开发或者前期的方案验证来说是非常方便的,缺点是灵活性较差。Arduino支持很多硬件,我们这一讲主要基于ESP8266和ESP32来讲解图片的显示。 1 硬件介绍 1.1 硬件配置 本文的硬件配置如下: 注:我这里...

If we want to initialize and create an array inside a function and then return it when the function is called, we have to use the dynamic memory allocation, which is done using themalloc()andfree()functions, and we also have to use the pointers in Arduino. ...

The following program is very similar to the above but uses a struct variable instead of lots of different ones. Note how you could use multiple struct variables in the program since pointers are used to display the contents of the struct variable 'StoreData'. ...
Understanding references and pointers Peter Dalmaris The topic of memory pointers in C and C++ is a known cause of intense headaches for many of us. It is the one topic that will most often scare people away from C/C++ and into "higher level" languages like Python and Ruby. But, with ...
