Hello Friends,Most STM32 based Evolution / Development Board has Crystal 32.768 Khz and Boot switch connected. In my Custom design board , I do not need RTC Function and Bootloader to load.8 Mhz Crystal is used for Master Clock. Can I remove 32.768 k...
Hello,I’m currently working with the STM32F103VET6 and experimenting with different peripherals to better understand how RCC, GPIOs, and timers interact — both from the block diagrams and the HAL layer.I've observed some unexpected behavior in the fo...
Hello,I have got an STM32U5G9J-DK1 and I want to use its VBAT pin which has been connected to the signal VDD_MCU, which is internal to the board, via solder bridge SB29. As far as my understanding of the data sheet goes, the VBAT pin is supposed to b...
On my dual-core STM32H747IGT6 I've got the CM4 doing data acquisition and processing, it's taking its output and storing it into shared memory (multiple possible destination buffers - some in SRAM1, some in SRAM2) for the CM7 to pick up. It's workin...
I am trying to do OTA programming modifications using the DUAL bank feature of my STM32U575 IC with 1Mbyte of memory.I have successfully done this when the program starts in BANK 1 and I reflash BANK 2. I change the User Option byte to OB_SWAP_BANK_E...
Hi guys, i am an embedded firmware engineer, with a lot of projects on stm32 micro controllers, including the communication protocols, battery management systems , ultra wide band, and EV charging, i wanted to know if i can post or share my projects ...

HiI use CPU pin 6 as ADC input ADC_IN12. I take measurements every 100us and save them to buffer[100] via DMA.I have a 1M+10k resistor divider connected to ground to the ADC input.I measure a rectified sine wave signal within 0..2V.To my surprise, af...
Hello,I have two questions regarding the STM32U0 series and the RM0503 reference manual:1/ HSISYS Divider ConfigurationIn RM0503, for the STM32U0 series, it is stated that HSISYS is a clock derived from HSI16 after division by a value from 1 to 128.T...
Hi, I am using STM32L476RG-Nucleo64 boards for one of my ultrasound projects. Basically, the process is:1)Send 2MHz pulses with pwm2) Sample 1000points with 8-bit interleaved ADC(500 each) and DMA3) Send ADC data through SPI.4) Wait TIM3 to trigger a...
