用430单片机编写的简单的示波器程序，型号2553.非常实用。(MCU with 430 prepared with a simple oscilloscope program, model 2553. very practical.)

SX1212程序，希望对想学习SX1212无线通讯的朋友有所帮助(SX1212 program, we hope to want to learn SX1212 wireless communications to help a friend)

这stm32f746代码描述如何两进行I2C数据缓冲区发送/接收 使用中断的电路板。(This STM32F746 code describes how to perform I2C data buffer transmission/reception between two boards using an interrupt.)

数码管是一种半导体发光器件，其基本单元是发光二极管。数码管按段数可分为七段数码管和八段数码管，八段数码管比七段数码管多一个发光二极管单元，也就是多一个小数点（DP）这个小数点可以更精确的表示数码管想要显示的内容(The digital tube is a semiconductor light emitting device. Its basic unit is a light emitting diode. According to the number of digital tube can be divided into seven digital tube and eight digital tube, eight digital tube seven segment digital tube more than a light emitting diode unit is a decimal point (DP) of the decimal point can be a more accurate representation of the digital tube to display the content)
