STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Using HAL_UART_Transmit_DMAUSART is in async mode, 115200,8,1,-DMA: Data width = byte (nothing else works)Any clues as to what could be happening here?Thank you!Ned
Hi. I am going through the STM32 Step by Step instructions, as well as going through the "Description of STM32F7 HAL and low-layer drivers" manual. I am using the STM32756-EVAL board so I have made some appropriate changes based on the pins and ports...
Hi everyone,A new issue has occur and have no idea as to why the transmission would be sometimes corrupt. I try sending the word "Hello World" as a test, however sometimes I would receieve the word but sometimes I would receivbe garage values that va...
In the RM0454 the chapter 14.9 is "Temperature sensor and internal reference voltage". It explain how to compute the actual VREF+ using the internal reference voltage. And the ADC has a VREFINT channel.But I can't find VREFBUF.In the datasheet (DS127...

Hi everyone,I am currently trying to learn rust embedded thanks to 3 stm32 based developpement board :Nucleo with STM32F103RBSTM32F3DISCOVERYNucleo with STM32F411REI have no issue with the first two ones but I can not make work the F411RE with gdb & ...
Hello,I am facing an issue with nCS pin of QSPI on STM32H747BIT.Reference manual indicates that SCLK is supposed to wait one period after nCS fall before starting operations :But I do not observe this wait on my board.*Yellow is the clock *Blue is th...
at the datasheet:LDO only - can work with VOS0SMPS directly cant work with VOS0.SMPS on and supplies only the LDO - ?
