stm32 iap jumps to isp to realize power-on isp download

Overview: This program waits for 3 seconds after power-on, and checks every 10ms whether the serial port receives a handshake command (0x7F). If received, it jumps to the isp program for execution. You can use the mcuisp software to directly upgrade the program through serial port 1. It is a simple iap program. The fi

STM32 stepper motor acceleration and deceleration

The acceleration and deceleration of the motor is to make the motor start and stop more stable and improve the uniform speed. The S-curve algorithm optimizes the operation of the motor. The whole process is to set the motor frequency by imitating the S curve The program uses the s_curve() function to map a table o

STM32 read protection function and clear read protection function settings [transfer]

1. STM32 protection measures for internal Flash All STM32 chips provide Flash protection to prevent illegal access to the Flash - write protection and read protection. 1) Read protection is commonly referred to as "encryption", which acts on the entire Flash storage area. Once Flash read protection is set, th

Detailed explanation of the difficulties of STM32 interface FSMC/FMC

The STM32F767's FMC divides the external memory into six fixed-size 256M storage areas, as shown below: The FMC memory block 1 (Bank1) of STM32F767 is divided into 4 areas, each area manages 64M bytes of space, and each area has independent registers to configure the connected storage. The 256M

Engineer's STM32 MCU Learning Basic Notes (4): Using PWM to implement firefly lights (I)

　　Using PWM to realize firefly lamp 　　Last time I mentioned that I would use the PWM function of the Timer to implement a firefly light. Of course, I still need to find an existing example to modify, and the example I will use this time is here. 　　　　Copy a copy to your own practice folder and create a proj
