Generally, ROM is used to store firmware, while RAM is used to hold data. Since FLASH ROM has faster read and write speeds and is easier to erase compared to ordinary ROM, it is typically used to store user programs and data that need to be permanently saved. For example, the core of a household … Read more
Learning about microcontrollers is a long and somewhat painful process.

1. What is a microcontroller? A microcontroller is a single-chip microcomputer that integrates a microprocessor, memory, and I/O interface circuits on one integrated circuit chip. Intel launched the MCS-51 series microcontrollers, which integrate an 8-bit CPU, 4KB ROM, 128 bytes RAM, 4 8-bit parallel ports, and 1 full-duplex serial port, along with 2 16-bit timer/counters. … Read more
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

The MSP430 microcontroller is a microcontroller launched by Texas Instruments (TI) in 1996. It is a 16-bit ultra-low-power microcontroller with a Reduced Instruction Set Computing (RISC) architecture. However, many beginners are not very familiar with the MSP430 compared to other microcontrollers like the 51 and STM32. Below, we will explain the MSP430 microcontroller, hoping to … Read more
It is well known that microcontrollers are the core of embedded development. To master microcontrollers, the choice of programming language is also crucial. However, if you have explored the programming languages for different microcontrollers, you will find that most people use C language. There is even a saying that “microcontrollers cannot do without C language.” … Read more
● Significance of the Watchdog 1、 The c language execution process In microcontrollers, c programs execute sequentially starting from address 0, where the PC pointer indicates the current execution address. For the STM32F407, as the code executes, the PC pointer continuously moves along the memory addresses. When it reaches the last statement of the main … Read more
