The operation of the chip mainly involves manipulating the registers within the chip. Each register has its own unique address mapped in memory, which is what we are operating on. To understand the chip, first look at the timing diagram, then understand the corresponding registers, how they operate, define the necessary ports (which the program … Read more
1.System Functions In the STM32 main control system, we implemented a 4×4 keyboard matrix interface for convenient input of student ID numbers. Users only need to press the corresponding number key, and the LCD1602 LCD screen will immediately display the entered value. Once the user enters a continuous sequence of 8 digits, pressing the “Confirm” … Read more
Follow,Star Public Account, don’t miss exciting content Editor: TonySource: Public Account TonyCode In the previous article, we used library functions to drive the DS1302 to obtain time data and output it via the serial port. The serial port is just for debugging; to create an electronic clock, we need to use a display module. This … Read more

Driving Part – DS1302 1 Introduction to RTC Real Time Clock, abbreviated as RTC, is also available in the STM32 peripherals, but the RTC of the STM32F1 series actually only has a counter function. If you need year, month, and day, you have to write software to calculate it yourself, which is quite troublesome. At … Read more
