I am working on an STM32N6 hardware design, and have reviewed both development kit reference designs (MB1939/MB1940). Both designs use the same power supply scheme, when using internal SMPS it has 2x 3V3 regulators and 3x 1V8 regulators.I am interest...
Experimenting with STM32F427 and STM32F446 I found out, that the RCC_CR.HSEBYP bit is *not* reset by Software reset. It is reset only by NRST and Power-On reset.While applications where this could lead to problems (i.e. where HSE clock source is chan...
Hello sir/miss , According to the STM32H7 datasheet, the range of the HSE external crystal oscillator is 4M - 48MHz. However, when we used the STM32H7IIT6-EVAL evaluation board and replaced the original 25MHz surface mount passive crystal oscillator ...
Hello,We are using the RTC wakeup timer and I have noticed that sometimes the WUTIE and WUTE bits are not being set. We are using HAL_RTCEx_SetWakeUpTimer_IT() HAL function to enable the timer. In stepping through the HAL code, it sets the RTC_CR_WUT...
Hello Community,We are currently evaluating the STM32H562IGT6 microcontroller for our development project. During our review of the device’s pinout, we observed that several GPIO pins are designated as FT (5‑V tolerant). We would like to request clar...
Hello, I've just received my custom PCB with an STM32H743VIT6 MCU. It has a Samsung eMMC connected to the SDMMC1 interface (MMC 8 Bits Wide Bus) : (I'll link the eMMC datasheet below.) I'm encountering some issues while initializing the device with ...
According to the STM32 datasheet, the maximum clock frequency of TIM6 and TIM17 is shown as 64 MHz, while that of TIM1 to TIM8 is shown as 200 MHz. There is a conflict in the documentation, so please confirm which one is correct. (DS14258 Rev6,page 1...
So on the page https://www.st.com/content/st_com/en/stm32-mcu-product-selector.html i cannoy filter out STM32 products which have higher resolution ADC converters built in, i need high resolution input (>16bits or eq SD) and there is no way to select...
We are working on a bare-metal application using USBX on an STM32N657X0H3Q device.In CubeMX, we configured USB1_OTG_HS under Connectivity and enabled USBX in Middleware. However, when we execute the following function: static void MX_USB1_OTG_HS_P...
New question = New thread. Split from this post. Hi mƎALLEm, Thanks for the support, I was able to successfully perform UART-based flashing. For the actual use case, I need to flash the STM32F767ZI Nucleo using the CAN interface. I have a PEAK USB-to...
