Sequent Microsystems designs and sells Automation Systems using Raspberry Pi. All our products use STM processors. We use about 10,000 processors per year in different configurations. Generally we do not have any quality problems, but occasionally we...
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...
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...
Hi,We have STM32N6570-DK and are testing camera input, video encode and write to SD cardWe have not been able to make the "VENC_SDCard_Appli" example work, the SD card just contains zeros.The "VENC_SDCard_ThreadX" example does work however, resulting...
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 wanna use the development board STM32N6570-DK for taking a picture with MB1854B. i am quite new for DCMI and DCMIPP. i just want to read the image through the pipe1 of dcmipp but i dont know how to config the MCU in .ioc file. Can anyone exp...
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...
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...
