Hello,ST announced the STM32V8 series some time ago (https://www.st.com/content/st_com/en/campaigns/stm32v8-high-performance-cortex-m85-mcu-z11.html), but there haven’t been any updates since then.I have a couple of questions:How can we download the ...
Hi, I am trying to establish CAN communication between three different MCUs: NUCLEO-H723ZG, NUCLEO-H755ZIQ, and NUCLEO-G474RE. However, I am unable to successfully communicate between the boards, even though the same baud rate has been configured on ...
On AN4879, STM32N6 is marked as Type E (Universal serial bus full-speed host/device interface) But actually it has 2 HS OTG with phy as high-end line up (2* Type D)
Hi!In version 4 of the reference manual for STM32U0, it is suggested that BOR is enabled and on Level 3 from the factory.Is that correct?I'm currently working on an construction running @ 2V, so it would never start up, if so. And when I read out the...
Hello, rm0456 in chapter 33.4.8. talks about "Software procedure to calibrate the ADC" and "Extended calibration mode" on some products. It is not clear, if "Software procedure to calibrate the ADC" is enough for products with "Extended calibration m...
We have both a very RAM constrained and space constrained board. So the OctoFlash chips are larger then i would like. So being able to XIP off a spi flash that only has 4 SPI lanes would be very helpful. I just don't know the ramifications of s...
Hi, I'm designing the board for STM32H755IIK6. My power supply plan is SMPS + LDO, since I want to use 480MHz speed. I wonder if there are better recommendations about 2.2uF VCAP placement. There are three VCAP pins, but two 2.2uF capacitors are ins...
When I write code, should I keep the microcontroller on, or turn it off and only turn it on when I want to test the code?
Hi,we are using the STM32H7R7I8T6 MCU with an Infineon S70KL1282 HyperRAM Chip attached on XSPI1 and configured via CubeMX, we are looking for an example for the correct timing/parameters to use the RAM Chip in memory mapped mode as Graphics RAM.Our ...
Why is it that when I set the clock frequency of the STM32 to a high frequency (180 MHz), the code will crash, but when I set it to a low frequency (72 MHz), the code can run normally?
