Hi guys.I have 2 GPIOs, one is used as a PWM, the other one is used as ADC.and the peak comes in the falling edge of the PWM singal.and the plus width is only like 2us.I want to get the value of the peak voltage using ADC.The problem is, if I use a i...
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...
