对于水平或垂直的线,有优化的线绘制功能,避免角计算: void drawFastVLine(uint16_t x0, uint16_t y0, uint16_t length, uint16_t color); void drawFastHLine(uint8_t x0, uint8_t y0, uint8_t length, uint16_t color); 绘制矩形 接下来,使用以下程序可以绘制和填充矩形和正方形。每个都可以输...
HTTPC_FORCE_FOLLOW_REDIRECTS进行重定向 void setRedirectLimit(uint16_t limit)单个请求重定向最大次数,默认为10; bool setURL(const String &url)重新设置url; void useHTTP10(bool usehttp10 = true)设置http协议版本,未调用该方法时默认为false,即默认使用HTTP1.1; int GET()向服务器发起GET请求,并返回状态...

void drawFastHLine(uint8_t x0, uint8_t y0, uint8_t length,uint16_t color);l 绘制矩形接下来,使用以下程序可以绘制和填充矩形和正方形。每个都可以输入矩形左上角的X、Y对、宽度和高度(以像素为单位)以及颜色。drawRect()只渲染矩形的框架(轮廓)-内部不受影响-而fillRect()用给定的颜色填充整个区域...

Also, if your code does any slow operations like Serial printing it will also limit performance. We disabled any printing in the tests below. We tested with RF22::GFSK_Rb125Fd125, which is probably the fastest scheme available. We tested with a 13 octet message length, over a very short...
Resistors are components with - as the name implies - anelectrical resistance, in other words, they limit the flow of electrons, so they are often used to limit the current. The SI unit of resistance is Ohms, often written as the Greek letter omega (Ω). They are often used with the...
Make sure the printer is connected and port and board type are set correctly. Press the upload button. That is the button with the arrow to the right. After a while you see the length of the compiled firmware file and the upload starts. On most boards you will see a led starting to ...
