PWM

在数字信号的基带传输过程中，信息传输速率在满足香农公式的条件下还极大地受到码间干扰的限制(It is also limited by intersymbol interference when transmission speed of code accord with Shannon expressions in the course of baseband transmission of digital signal.)

说明：  STM32L151控制SYN6288语音合成，包含原理图，能成功合成语音(STM32L151 controls SYN6288 speech synthesis, including schematic diagram, which can successfully synthesize speech.)

说明：  外汇ea交易系统，趋势智能交易，稳定，可以测试(Exchange EA trading system, trend intelligent trading, stable, testable)

STM32F103RBT6和W5200网络芯片的服务期端的测试程序，减少了很多不必要的设置，测试更方便(W5200 STM32F103RBT6 and end of service network chip testing procedures, to reduce a lot of unnecessary settings, the test is more convenient)
