The working principle of the microcontroller reset circuit and the difference from the set position

The setting and resetting of the microcontroller are both for initializing the circuit to a certain state. Generally speaking, the function of the microcontroller reset circuit is to initialize a state machine to an empty state, while inside the microcontroller, when resetting, the microcontroller loads some regis

Study the operation of PIC microcontroller program under PICC compilation environment

PICC basically complies with the ANSI standard, but does not support recursive function calls. The main reason is the special stack structure of the PIC microcontroller. The stack in the PIC microcontroller is implemented by hardware, and its depth is fixed with the chip, so it is impossible to implement recursive alg

What is stored in the STM32 microcontroller flash memory?

First look at rom, which is flash (0x0800 0000-0x0807 ffff) 51 2k . This space is where users store programs. When users write their own boot loader in the future, they will also store it in this space. The system memory space is 2k in size. It is the ISP code that ST company has solidified when the film is produced

Design of non-invasive visual pulse oximeter based on MSP430 series MCU

A pulse oximeter is a medical device used to monitor a patient's blood oxygen levels. The device measures blood oxygen levels and heart rate and generates an alarm when levels drop below a predetermined threshold. This type of monitoring is extremely useful for newborn babies and during surgical procedures. The
