STM32 MCUs Products

Hello, I need to receive, from usart, a non kown amount of data, is there any implementation of DMA ring buffer for HAL library and stm32f407? Thank you.

STM32H743 UART read/write to/from PC and MCU

Hey there,I was wondering where I could find some resource materials for configuring UART to read and write to serial or if I could get a hand with it. Using CubeMX, I've enabled USART3, USB_OTG_FS, and and the USB CDC middleware, but still can't see...

SDIO (with DMA) does not respond after inactivity

Hello to the community!I've run into a strange problem on my STM32F7:I init, mount and open a file directly after the uC initif I read this file often (from my main() while(1)), I never have read problems (it can works for hours)if I don't read the f...

STM32G071CBT6 LQFP48 package. Internal voltage buffer available? Seems not!

Can Bus store message

Hi all, I’m trying to test the can bus function with the STM32F042, I’ve studied all the Datasheet but I’m trying to find the best solution for an efficient store for incoming messages..My question is if I don’t know the right amount of incoming ID ...

STM32L452xx: Memory mapping calculation

Looking at the datasheet of the STM32L452xx family, it's noted that SRAM size is 160K.The memory mapping on page 86 notes the address range from 0x2000'0000-0x2028'0000.But 160K is 0x2'8000 and not 0x28'0000, which would make the range from 0x2000'00...

[SILICON BUG?] STM32F3 DAC has 4LSB sawtooth with 1 minute period

Over the past month, I've been trying to figure out if the DAC in the STM32F3 actually has a silicon bug. I observe a sawtooth with an approx 1 minute period in the DAC output (as measured by the ADC on the same chip). The first large "tooth" is alwa...

DS12288 - STM32G474xB Datasheet - Errors

Page 118, Table 38 has "1.78" in Peripheral column instead of TIM1.Page 115, fourth bullet says "... is given in Table 39. The power...". The table number should be 38.
