Funny statement in STM32C071 datasheet
Section 3.20: "It requires a precise 48 MHz clock that is generated from the internal high-speedexternal clock source"So we have "internal external" clock source. ;)

Resolved! Unable to Configure STM32H7B0VB for SDRAM
For my current Project, I decided to go with the STM32H7B0VBT6 from the STM32H7B0VB family. However the 1.4MB SRAM of the MCU was too little for me, so I've chosen to go with an external SDRAM (IS42S16400J-7TLI [64 MBit | 8 MB). Now I wanted to get t...
USART not working when using HSI in STM32F769-Discovery
Hi, I am new on STM32 and I started a product prototype using STM32F769-Discovery. I developed all software using default clock configuration, which uses HSE. Now I want to change to HSI, but USART is not working ( Not true, only works when board res...
Resolved! STM32H562RGT6 RAM address order
Hi,we are examining if we can apply our March-C test to the STM32H562. It is tailored to the RAM address order of the STM32F446. Unfortunately, the documentation does not seem to provide any hints here. Is there a difference in RAM address order betw...
MPU on STM32H755
I'm having a hard time figuring out how to configure the MPU of my microcontrollore in order to have this behaviour.I've a framebuffer in ram that is big 384KB. I've modified my linker in order to have the framebuffer starting at location 0x24022000T...
MCU is not recognized as USB storage device
Hi all - I'm new to the STM ecosystem and I've been stuck on an STM32H743/ Micropython issue.My (custom) board can upload Micropython firmware via both SWD and DFU. So DM/ DP work.VCC measures 3.21V, maybe a little low, maybe just my DMM.I'm not able...
Resolved! Serial SPI in one slave
I have two MCUs and I connected them by SPI, one of them is master and another is slave.On slave MCU, I used two SPI1 and SPI2 and I connected them serially by wire, sometimes connect and disconnectthem by S1, I want to ask is it possible to have thi...
Resolved! Use of ADC
good morning everyone, i am trying to use the ADC of the stm32h745 disco. for that i connected my ADC to a breadboard with a potentiometer. I wanted to change the value of the potentiometer so i can see on my computer the values. I got inspired by th...
Resolved! E-Stop by resetting
I'm using Nucleo32-F303K8. I'm running low on pins and can't upgrade to a bigger MCU. I was thinking of using NRST pin as an E-Stop. Would that be a good idea? The GPIO pins would be externally driven low or high while under and after the reset, espe...
Resolved! STM32G0B1 FDCAN message Cycle time fluctuating
Hello, I am using STM32G0B1, i have implemented the FDCAN communication but the issue i am facing with the cycle timei have set the cycle time for 500ms i.e. every 400ms CAN messages will be transmitted. every thing works good until i am not receivi...
