Hi everyoneI'm trying to get the ADC1 running with a DMA transfer on the STM32H757ZI. The goal is to measure 10 channels with 8 samples each and transfer these measurements to a separated SRAM1 buffer with DMA, each time the conversion sequence has b...

Hello,I am trying to receive an unknown length of data on a UART on a STM32H7A3I have declared a buffer to receive the data and aligned it :#define UART_RX_BUFF_SIZE 256 ALIGN_32BYTES (static uint8_t uart_buff[UART_RX_BUFF_SIZE]);Then as I am working...

From the latest ST emailshot:https://www.st.com/content/st_com/en/ecosystems/MadeForSTM32.htmlWhat, exactly, are the "quality" metrics?In particular, what does a "strong" customer service actually mean?There are some current "partner" products with n...
Hello, I'm currently working on an STM32G031G8U on a custom PCB. I can't really debug the code as I don't have access to ST-Link or SWDIO/SWCLK pins.I haven't managed to set TIM1 internal clock to 128 MHz as stated in the reference manual (section 5....
That's how I would understand it. When I set the output as open drain I need an external pull-up (or pull-down) resistor. Is there a reason I SHOULD use the external resistor? If so - what does this configuration option (pull-up, pull-down) mean exac...
