Hi everyone!I am trying to get the lowest power consumption from the STM32L073ZR in STOP Mode.I run my tests with the board powered from external source E5V (no USB connected).I have two Ampere-meters:one measure the current IDD of the microcontrolle...
Posted on August 03, 2017 at 20:26Hi, recently in a project I need the GPIOs on STM32 to operate on 1.8v logic level. By quickly looking through datasheets, it seems many of STM32 can do so, for example, to STM32F407VG, if provide 1.8v to VDD, it ru...
Hi Team,This IC STM32H745XI will support the following power supply configurations 1) Direct SMPS power supply which gives to the core domain 2) Direct LDO power supply which gives to the core domain 3) SMPS ->LDO-> Core domain(1.8v or 2.5v) 4) Exte...
I want to know how to split the flash memory of the stm32f103c8t6 , The one part of memory is used to store the firmware & other part is used to store the settings & configuration through external user interface exe file. Please any one help in thes...

Hello,This is for the STM32H7, but may be applicable to other STM32 chips.Is there a way to do a continuous DMA stream from a UART without requiring an expected size?I would like to be able to set up a receive buffer with DMA in circular mode, and ju...
freqError = static_cast<int32_t>(readRegister(REG_FREQ_ERROR_MSB) & B111);C has no static_cast, so how can I convert the above code to C?(It 's C++, from Arduino)
I'm using QuadSPI in indirect dual-flash read mode to transfer data from an external chip (not flash memory). According to reference manual, when FSIZE = 0x1F and DLR = 0xFFFFFFFF, the transfer should continue indefinitely.However, with STM32H743ZIT6...
