在本应用笔记提供的示例中,软件子程序每秒一次连续读取32位秒计数器的数值,并通过8051微控制器(µC)的UART接口以ASCII码格式输出时间和日期。时间和日期基于从1970年1月1日,00:00:00起所经历的时间,单位为秒。00000000h对应的时间是1970年1月1日,00:00:00;42C924C0h对应的时间为2005/7/4 12:00:00。
RTC Interfacing with 8051 Microcontroller I2C devices have open drain outputs therefore, a pull-up resistors must be connected to the I2C bus line with a voltage source. If the resistors are not connected to the SCL and SDL lines, the bus will not work. ...
Three Phase Solid State Relay with ZVS Project Block Diagram by Edgefxkits.com The IC L293D is used for interfacing 8051 with DC motor as shown in the block diagram. The two input buttons can be used to control the output PWM generated by the microcontroller. This output signal is then ...
