IAR升级之后,打开stm32官方例程,编译时提示如下错误: Error[Pe147]: declaration is incompatible with "__nounwind __interwork __softfp unsigned short __LDREXH(unsigned short const E:\My doc\STM32F10x标准库v3.5.0\STM32F10x_StdPeriph_Lib_V3.5.0\Libraries\CMSIS\CM3\CoreSupport\co
CYPREE提供的FX3_SDK开发包里面有很多基础的内容,除了前面提到的几个pdf文件外,还有三个文件夹,是官方提供的基础例程.学习CYUSB3014应该就从这里开始,从这几个例程开始.例程共有三个文件夹,分别是basic_examples,slavefifo和u3p_firmware.最后一个是与USB Video Class相关的例程:中间一个是Slave FIFO相关的例程(同CY7C68013概念相同),其下含有两个例程,分别对应同步与异步传输:第一个文件夹是最基本的块传输(Bulk

The Application example shows how to implement a standard GUI application with menus, toolbars, and a status bar. The example itself is a simple text editor program built around QPlainTextEdit. Nearly all of the code for the Application example is in
这个例子演示了如何使用QPainter的转换和缩放特性来简化绘图. 值得学习的: 定时器事件ID检查: 在定时器事件中检查定时器id是比较好的实践. QPainter抗锯齿: We call QPainter::setRenderHint() with QPainter::Antialiasing to turn on antialiasing. This makes drawing of diagonal lines much smoother. 画笔的平移/缩放: p->translate(
