Summary of C51 Microcontroller Programming Points 1. Header file: #include (I am using STC 89C54RD+) 2. Pre-definition: sbit LED = P1^0 // Define bit 0 of port P1 as LED Note: The notation “P1^0” is different from A51 (A51 uses P1.0). P1 is a group of ports, and the port number ranges from 0 to … Read more
I have always been curious about a question: every time I finish writing a microcontroller program and use the burning software to upload it, I can see the size of the burning file, which is the hex file size: The microcontroller chip I am using is the STM32F103C8T6, which has a program memory (flash) of … Read more

Introduction Since both the Arduino controlling the lead screw and the board controlling the servo only have one UART, they need to communicate with each other, and also with the Raspberry Pi. Therefore, the number of UARTs is insufficient. Thus, I created a UART Data Manager using the STM32F103 chip, which has three UARTs: USART1~3. … Read more
1. Introduction When learning about the 51 microcontroller, we often use the combination of Keil and Proteus for experiments. This simulation saves us a lot of hardware and time costs, allowing us to visually observe the execution process of the code. However, when switching to the STM32 series microcontrollers, Proteus is obviously not supported, but … Read more
