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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...

Posted on June 02, 2017 at 10:44Hi everyone,I cannot connect the STM32F405RG MCU with ST-Link Utility and IAR Embedded Workbench.I need your help, How can i connect MCU again ?I tried Connection Settings --> SWDMode --> Connect Under ...
Posted on June 01, 2017 at 18:53Hello to the community,Due to an error on a board routing I have ended with a bunch of boards with the RX and TX pins of USART1 incorrectly routed to PB4 and PB5 pins of STM32F103.I wonder if there is any human way of...
Posted on May 30, 2017 at 11:26Hi,I am using the NUCLEO - L053R8 circuit board.I question about 5 V tolerant function.A pull-up resistor driven by 5 V is added to the port of PA_8.In this case, when setting the open drain setting, 0.1 mA flows.Howev...
Posted on June 01, 2017 at 22:54Hello world,i got an STM32F410TB which somehow freezes after a special external failure. In my application the powersupply voltage is gone for about 60-70 ms. The buffer capacitors are discharged and the supply voltag...
Posted on June 01, 2017 at 20:44After waking from a WFI instruction, it appears my GPIO and possibly other processor configurations have been changed and are not correct. The Reference Manual implies Sleep Mode does not affect any settings. I see tw...
Posted on June 01, 2017 at 13:10HiI am a new ingineer (still student in ingineering school) and I need to test the possibility to use some optical fiber sensor in order to mesure a mouvement (inside a black cavity or by reading a black and white rul...
Posted on June 01, 2017 at 11:40Hi St Community,I’m working on CAN J1939 protocol, with two STM32 F103RB - Nucleo64 and two transceivers (MCP2551). I’m looking for decrease the data rate to 250 Kbits/s but I have no idea of how to do that. Shoul...
Posted on June 01, 2017 at 07:51Hi all,I am using stm32f030RC controller,for my application need to print the float values on the hyperterminal.Printf is working fine for text,charters & interger values.i am using stm32cubemx generated code & atolli...
Posted on June 01, 2017 at 13:45Hi all:I wonder how UART error handling works when using DMA on an STM32F4xx, although I do use STM32F0xx microcontrollers too.If a parity or frame error pops up, what is the best way to handle it? I guess you cannot ...
