STM32 BOOT bit understanding and setting-EEWORLD

Collect

The STM32F10x on-chip storage area has three parts: built-in Flash, built-in SRAM, and built-in ROM (system memory). This defines three ways to start the system: starting from built-in Flash, starting from built-in SRAM, and starting from system memory. These three startup methods are determined by the two pins BOOT[1:0]. STM32 BOOT bit understanding and setting

SRAM: The RAM area built into the chip, commonly known as memory.
System memory: A specific area inside the chip. ST burns a Bootloader into this area when the chip leaves the factory. Since this area is ROM, the chip cannot be modified after leaving the factory. The main task of this Bootloader is to download the program to the built-in Flash through UART1. BOOT selects the System memory mode. After completing the task, it must exit. This can be achieved by reconfiguring BOOT[1:0] to select the appropriate startup mode and then resetting the hardware.

STM32 cannot print floating point numbers via %f

1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can be seen that the floating point part cannot be displayed normally. 2. Solution This is because the printf library sele

STM32 Learning Road (Part 3)——GPIO+USART Joint Debugging

I'm used to watching tutorials that only play "lighting up" for the first time, which is boring. This time I'm going to play with the serial port and "lighting up" together. You need to read more about the relevant registers and library functions beforehand. There are a little too many, but you will get used to it soon

About the problem of STM32 serial port idle interrupt IDEL

1. The idle interrupt is triggered when a byte of high level (idle) appears after receiving data. It does not mean that the idle interrupt will continue. To be precise, it should be a byte after the rising edge (stop bit). If it is always at a low level, the idle interrupt will not be triggered (it will trigger a brea

Some thoughts on STM32 driving DS1302

I have used 51 to drive DS1302 before, and it output the correct time in a short time. At that time, I thought this chip was simple and simple. But now I use STM32 to do a project, using the same chip, and I think it is not difficult. I just need to copy and paste the program and change the IO settings. But things are

STM32 MCU releases PB3/PB4/PA15 as common IO port

　　When using multiple IO ports of STM32F103RCT6 microcontroller, I found that no matter how to configure, PB3, PB4, PA15 could not control the output high and low levels normally, while other IO ports were normal. The IO port initialization operation is as follows: GPIO_InitTypeDef GPIO_Init; __HAL_RCC_GPI

STM32+UCGUI+touch screen

I recently studied ucGUI, and the functions are OK. The first functions are quite simple, but I encountered a little difficulty when studying the touch screen. I created a button, but it always didn't respond when I clicked it. I finally got it done after nearly a day of tossing. Let's briefly introduce th
