这是AD9910 DDS芯片的verilog配置程序，经调试已成功，可以供大家参考。(AD9910 verilog configuation.)

使用STM32F4+usb3300实现虚拟示波器,支持使用外部ADC模式，也就是使用AD9280芯片，最大采样率可达30MSPS.(STM32F4+usb3300 implementation of the virtual oscilloscope, support the use of external ADC mode, that is, the use of AD9280 chip, the maximum sampling rate of up to 30MSPS )

NTC热敏电阻计算器（B值、R25、指定温度、指定阻值均可计算，给定四个参数即可计算第五个参数）(NTC thermistors Calculator (B value, R25, specified temperature, the resistance can be specified calculation, four parameters can be calculated given the fifth parameter))
