How to set up J-link for STM32 using J-Flash download

J-link can debug almost all arm chips, it is a good thing. Here are three ways to download programs for stm32: 1. J-Flash download (requires J-link) 2. MDK configuration download (requires J-link) 3. ISP download (serial port download, you need to use the official serial port download software, those who have used stc

[STM32 Motor Vector Control] Record 14 - Hall Sensor

Hall sensor: The Hall sensor is a sensing device that can identify the polarity of the rotor magnetic field; the Hall sensor The Hall sensor must be mounted on the rotor to output logic level 0 or 1. Three Hall sensors are usually installed in a three-phase permanent magnet motor to provide feedback on the rotor po

stm32 interrupt vector controller

NVIC, Chinese name Nested Interrupt Vector Controller, is a unique integrated unit inside the Cortex-M3 series controller, which is closely integrated with the CPU, reduces interrupt latency and can handle subsequent interrupts more efficiently. For example, when buying tickets at a train station, the rules and regula

STM32 clock configuration

1. In STM32, there are five clock sources: HSI, HSE, LSI, LSE, and PLL. ①HSI is a high-speed internal clock, RC oscillator, with a frequency of 8MHz. ②HSE is a high-speed external clock that can be connected to a quartz/ceramic resonator or an external clock source with a frequency range of 4MHz~16MHz. ③LSI is a low-s

How to code the STM32 serial port to receive messages more stably

In "STM32 Serial Port Says Hello to the World", we introduced how to send messages, but how to receive messages? It is also very simple. You only need to configure the serial port reception, configure the interrupt, and receive data in the serial port interrupt function. The general configuration code is as follows: /

STM32 learning notes (VII) timer interrupt

stm32 uses systick to accurately delay

To achieve precise delay using the system tick timer, the following five steps are required: 1. Set the tick timer clock by setting its control register and selecting the external clock, which is one eighth of the system clock. If the system clock is 72M, the tick timer clock is 9M. That is, it takes 9M clock cycles t

STM32 USB Problem Summary

The following is a summary of what I learned when I modified ST's Custom_HID routine into a "custom USB device" routine. Because I have just started learning USB development, some misunderstandings are inevitable. Please correct me if I misunderstand them. 1. usb_desc.c file Modify it according to the communication
