除了使用外部的工具(如下载器)读写内部FLASH外,STM32芯片在运行的时候,也能对自身的内部FLASH进行读写,因此,若内部FLASH存储了应用程序后还有剩余的空间,我们可以把它像外部SPI-FLASH那样利用起来,存储一些程序运行时产生的需要掉电保存的数据。 由于访问内部FLASH的速度要比外部的SPI-FLASH快得多,所以在紧急状态下常常
使用STM32H743VIT6芯片时,系统时钟为400MHz,从片上Flash读取数据时,有时会进入hardfault。对flash全部...
I want to display 2 parameters(ID and BD) value on seven segment display. The values will be dynamically changed, so every time I want to write these 2 byte of values on FLASH memory and every power ON or System Reset, I want to Read that values from Flash Memory. Before writing any...
/*读取stm32的unique id 与 flash size*//*func: unsigned int Read_UniqueID_Byte(unsigned char offset) desc: This function is used to read the unique ID in flash. parameter offset is the byte offset ,the max is 96/8= 12. return: the return value is indicated part of the unique ID.*...
The FlashStorage_STM32 library aims to provide a convenient way to store and retrieve user's data using the non-volatile flash memory of STM32F/L/H/G/WB/MP1. It's using the buffered read and write to minimize the access to Flash. It now supports writing
When the write protection is set for the sector i (option bit nWRPi = 0), this sector cannot be erased or programmed. Enabling or disabling the write protection can be managed either by an embedded user code or by using the STM32 ST...
esp_flash_read 头文件 前言 最近想搞ESP32了,相中它的WIFI、蓝牙功能。 STM32寄存器开发习惯了,身为一个老顽固,底层还是想用寄存器开发(IO、通信啥的)。 使用VSCode开发,Keil和IAR这种开发软件不需要配置啥,没接触过感觉寸步难行,头文件的包涵就有问题了,不知道是不是我打开的方式不对,一直搜不到解决方法,...
I have an STM32 microcontroller on a device, which I program using ST-link. Due to a power issue, or something, suddenly few flash pages have become read protected. I don't know how to reverse this. I use the ST-link Utility tool in windows, and I tried to perform full chip erase...
