How can I Turn a Pwm signal in to a High (one) in the same pin?
I´m using a PWM signal and the complementary with TIM1(timer1). The Pwm´s complementary singal is going out from pin A7, then I want to turn off the pwm signal from that pin and turn on a HIGH value (one) in the exact same pin (A7). I want to do tha...

HRTIMER input frequency
Can the HRTIMER input frequeny be lower than the maximum value given in the datasheets? E.g. on a G74 with HRTIMER input at 125 MHz, steps would be nice 250 ps versus 188.2... ps at 170 MHz.The functional description "HRTIM timer is made of a digital...
How to detect interrupt by a timer?
Hi all,I know how to program a time base interrupt by a timer in HAL, but now I'm learning about do it in CMSIS, with a STM32F303CCT6 MCU.My question is, in RM0316 doc, page 287, it talks about the Interrupts and Exceptions Vectors, wioth a total of ...

hi i working on stm32h743vit to have two uSD card Simultaneously i use fatfs and SDIO 1 and SDIO 2each sd card working in Single mode for SDIO 1 and SDIO 2but i merge and change something to work correctly but in main just mount work ....i cant find ...
Resolved! STM32H743 Cortex-M7 core revision?
Hi!I was wondering which ARM Cortex-M7 revision does the STM32H743 uses.Does all the H7 family use the same core rev?Asking because we currently have a STM32F746 and we want to avoid de single stepping bug while debigging from the r0p0 and r0p1 core ...
STM32L4 Wrong MSI speed
Hello! I noticed a speed error on MCU L476 and L433. When setting MSI frequency to 1 MHz, the frequency is 1015.5. (Auto trimered by LSE, LSE enabled and work well) At higher frequencies, the operation is normal. What could be the reason?
Hi everyon! It is my first time to programming STM32 mcu and my task to send sesnsors data to a server. I chose to use mqtt protocol for this task. I find eclipse phao mqtt client which written in c language. Can somebody tell me how can i use this lib?
I set up mcu with CubeMX ethernet is used in MII mode.
