STM32 MCUs Products

Hi, In stm32H757 there is no X-CUBE-CRYPTOLIB so i downloaded it from the official website. My question is how can i add it in the IDE like anyother expansion package

FDCAN classic in stm32h7 stop receiving data after some time

Hi, Am interfacing STM32H743 FDCAN classic with STM32F7 CAN. When I tried transmitting data from F7 to H7, within a minute H7 stop receiving data. I also tried debug the problem on F7 side and found that breakpoint hit on following condition inside t...

Flash writing issue

Hi I'am using two different boards stm32f411 and stm32h723zg, so I am trying to write one byte data on flash which is 0xFF -> 0x70-> 0x10 -> 0x00 on same address in the sequence without erasing the flash, it’s working for stm32f411 but it doesn’t sup...

Question about chained timers (again) and how to avoid wraparound glitches

Hello, I ask this same question a month ago, but i want to reformulate the question to better understanding. I need to implement a lifetime counter using the nucleo-stm32L432kc timers to send the number periodically to an AFBR-S50 sensor. I think the...

There doesn't seem to be support for the stm32c series in Keil MDK. I was told that the device support packs are provided by SiPs nowadays, so is there any plans for this and could you give us an ETA?

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...
