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 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 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 ...
Posted on May 30, 2017 at 20:54So, a stm32 Nucleo (little sticker indicates -F411RE) was left on my desk. I looked at tools and got System Workbench installed. I figured a first test (of myself, the board, and the tools) would be to modify LED bli...
Posted on October 26, 2016 at 08:45Hello experts, when compared the block diagrams of STM32F7 and STM32H7, STM32H7 seems to have no ART accelarator. Cannot software access to the internal Flash without any wait cycles? Best regards, Yasuhiko Koumoto...
