stm32 --- Flexible static memory controller FSMC

All external memories share the address, data and control signals output by the controller, and each external device can be distinguished by a unique chip select signal. The FSMC only accesses one external device at any one time. Devices with static memory interfaces include: 1. Static random access memory (SRAM)

STM32 key interrupt learning record

I am used to searching the Internet when I encounter problems in debugging programs. I can often get inspiration from the records or replies of experts. I didn’t expect that one day I would start writing a blog to record my learning bits and pieces. The month of learning STM32 was a bit like working in isolation, beca

STM32 study notes: Bootloader upgrade Ymodem protocol introduction

YModem Protocol The YModem protocol evolved from the XModem protocol. Each data packet can reach 1024 bytes and is a very efficient file transfer protocol. Source code macro definition #define SOH (0x01) /* start of 128-byte data packet / #define STX (0x02) / start of 1024-byte data packet / #define EOT (0x04) / end

Analysis of TCP/IP protocol stack code ARP (STM32 platform)

1. Introduction to ARP Address Resolution Protocol ARP provides dynamic mapping between IP addresses and corresponding hardware addresses. A translation is required from the logical Internet address to the corresponding physical hardware address. This is the function of ARP. The function of ARP is to provide dynamic m

STM32 learning EXTI

EXTI has two functions: one is to generate an interrupt, the purpose is to pass the input signal to NVIC, further run the interrupt service function, realize the function, at the software level; the other is to generate an event, the purpose is to generate a pulse signal for other peripherals to use, this is the circu

Design of wireless communication terminal system based on STM32

1. Introduction 　　Currently, most instruments and equipment use RS232 interfaces to communicate with computers. However, with the development of computer technology, the hot-swappable USB standard interface will replace the RS232 interface. Therefore, computers will be less and less equipped with RS232 interf

STM32 MCU GPIO register

Each GPIO port has two 32-bit configuration registers (GPIOx_CRL, GPIOx_CRH) to control the high and low eight bits of each port respectively. If the IO port is 0-7, write the CRL register, if the IO port is 8-15, write the CRH register, two 32-bit data registers (GPIOx_IDR, GPIOx_ODR), one is read-only as input dat
