We have developed a number of products based on STM32Fx processors and can now no longer find stock to buy. If you look on Farnells website they stock over 1000 different STM32 processors with only 4 in stock and the rest on a 1 year lead time.

What is 0.5 bits or 1.5 bits?
I understand that what is shown in the picture is wrong, I just do not know how else to describe it.0.5 bit is 50% duty cycle?And 1.5 bits is 150% duty cycle?If the percentage of filling changes by 150%, then the data transmission frequency must also...
Register Level programming questions
I am just starting out with STM32 MCUs. Because I like pain, I am trying to do register level programming to make sure I really understand what the code is doing (rather than using automagically generated code). My environment is Visual Studio with...
STM32L552ZE FMC throws Hard Fault only when accessing sub-banks 2-4
Hi,I have configured the FMC for interfacing with a NOR flash on sub-banks 1 and 2 (NE1, and NE2). The FMC is configured for 16-bit data bus with 26 address lines. What follows is the configuration for two sub-banks on NE1 and NE2:/* FMC initializati...
Resolved! How to setup SPI DMA on the M4 core for the STM32H745 chip
I have a hobby project where I'm looking to design a flight controller using the STM32H745 microcontroller. My plan is to use the M4 core for data acquisition while using the M7 for the flight control stuff. I have a custom PCB with sensors connecte...
Resolved! Issue with memory allocation updating on its own.
Hi I am using Atolic TrueStudio and have some global variables. For some reason one variable is simply updating every time I step through the code with the debugger. I am using a STM32L433 processor and have 56k ram free. The variable is a character...
I have a project using stm32f765,now i want to migrate to stm32H743.I want to know if i can use the code that has been written for stm32f765 instead of writing a new one, If yes , is it enough to only change the header files name?
Hi community. I mean for example are some changes necessary in some HAL or LL APIs for different peripherals or i should leave it as the way they were written in pervious code(Code for stm32F765) ?
D flip-flop
Hi,I need to normalize the asynchronous transmission to a specific baudrate in real time. I know flip-flop D is fine, but I don't want to add extra elements to the layout. Can I do it with timers or maybe some other solution?
