When I try to put together a 64-bit write from combining the FDRL register and a 32-bit RAM access to the other part (if it is not corrupted), the successful handling of a single fault is followed by a false si
AN4736 Application note How to calibrate STM32L4 Series microcontrollers internal RC oscillator Note: Introduction The STM32L4 Series microcontrollers have two internal RC oscillators that can be selected as the system clock source. These are known as the HSI16 (h...
Every STM32 MCU comes pre-programmed with a system memory bootloader stored in the internal boot ROM (system memory). Its main purpose is to download the application program to the internal Flash memory through one of the available serial peripherals on the target device (e.g. U...
AN4991 Application note How to wake up an STM32 microcontroller from low-power mode with the USART or the LPUART Introduction The universal synchronous/asynchronous receiver transmitter (USART) and the low-power universal asynchronous receive tr...
Before starting, the first step is to prepare the environment to be able to go through the OEMiRoT process. Download the STM32CubeH5 package and install itWarning Place STM32CubeFW_H5 Cube firmware close to the C: root to avoid a long Windows® path. An...
In this tutorial we will cover how to use USB Mass Storage Class (MSC) in STM32. There will be two parts to this tutorial. In the first part we will allocate the RAM as the storage and read and write the data to this allocated portion. And in the second part, we will use the ...
How to modify frequency of acquisitionThis article describes how to use the sampling frequency parameter. This parameter is usable for direct mode and snapshot mode. In direct mode the sampling frequency is the frequency at which the variables are read out from the memory target. In the ...
因为不熟悉stm32,所以看了网上很多的DMA串口的例子,都是依赖中断的。中断的问题在于无法保证收到完整的数据包,但听说闲置中断可以解决这个问题,可能效果更好一点。但为了让代码有更好的跨平台特性,我还是想不用中断解决高速的、不定长度的串口收发问题,这里提出一种解决办法。

to implement a bootloader. A bootloader should be able to read and write to its flash memory. In my previous post, I wrote about how to read from flash memory. In this post, I will show how to write to flash memory. I am using an ARM Cortex-M4 microcontroller from ST, STM32F411...
