Hello, I made board with STM32H7 and i am running UHS example.First time i always get 48MBps write and 65MBps read, but at the second debugging i get only 8MBps read/write speed, and i have to remouve card and insert it again to get back to that blis...
It looks like I made a fatal mistake by connecting the NRST pin to the PA0 pin on an STM32F778AIY. This is a part with no internal voltage regulator for the core so the PA0 pin acts like a power on reset. This hasn't caused problems with power cyc...
Does anyone know if I can change the PWM signal period in the main loop? after initializing the timer in Cubemx?
I want to create files in this flash drive with a stm32f303 program and i want to transfer these file on pc in real time ....

In my software, I usually extend the 24bit SysTick handler to 32bit with the tricks shown in the code segment below. Using such a do-while construct as shown in "GetSysTickCompleteVal" I usually prefer for the fast access to volatile interrupt data, ...
i am using STM32L4S5 series controller which contains 2MB flash. recently I got a problem like Read out protection activated. Because of that i am not able to read write as well mass erase also. And then i read the options registers from 2 boards (on...
Thank you for new I2C interface, this really is supergreat compared to the cumbersome STM32F4 solution. My new STM32H7 I2C code is only about 20-30% of the STM32F4 version - I use a state machine and needed > 10 partly extremely cumbersome states in ...
Hello,I have a very weird behavior...When trying to access external synchronous PSRAM.I see the clock and cs change only if I stop and starts stepping inside the while(1) loop below. When doing "go", there is no clock nor CS changes.I tried to add de...
Hi community,I'm using the STM32F072 Discovery kit (https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-mcu-discovery-kits/32f072bdiscovery.html).The ST-LINK/V2 embedded de...
