The clock circuit is an oscillator that provides a rhythm for the microcontroller. The microcontroller must operate under this rhythm to perform various tasks. Therefore, the microcontroller will not function properly without a clock circuit. The clock circuit itself does not control anything; rather, it is the program that allows the microcontroller to perform corresponding … Read more
01 Inside the MCS-51 microcontroller, there is a high-gain inverting amplifier, where the input is XTAL1 and the output is XTAL2. The oscillation circuit formed by this amplifier and the clock circuit together constitute the clock mode of the microcontroller.Depending on the hardware circuit, the clock connection methods of the microcontroller can be divided into … Read more
Figure 3 PCB Wiring 4) Circuit Related Explanation As shown in Figure 1, R56 and R57 are the pull-up resistors on the I2C bus. The interrupt output and clock output of the PCF8563 are both open-drain outputs, so external pull-up resistors are also needed, such as R58 and R59 in Figure 1. If these two … Read more
