STM32 MCUs Products

Is there a simple way to prevent that the STM32F0 is supplied parasitic through the protection diodes of the GPIOs? The device seems not to provide a brownout reset circuit, or am I wrong?

We use a STM32F0 in an application with increased safety requirements. The power supply is secured by a simple fuse and we have to assure that the STM32F0 is in reset state when the fuse is blown (EN60335).Since we have a second power supply in the s...

Any ready to go Linux images for STM32F4/F7?

Hello,are there any ready to use linux images for STM32F4/F7 beside the 2.4 uCLinux image for the f4 disco from 2013? https://github.com/fdu is a good start, but I can not get uBoot to recognize the files on the SD card.

Dear Member, I want to parse GGA,GSV,ZDA,VTG,RMC,GLL,is my container not enough ?Sometimes I can parse it sometimes I miss......?line_buffer[2048];uint8_t      rxBuffer[768];      str=strstr((char*)GPS.rxBuffer,"$GPGSV,");            ProcessNMEALine(...

The address of the variable is the same

i using FreeRTOS.MB_Coil_Counter is a global variables and tmp is a variable in interrupt function of uart!why the address of tmp matches the address of MB!thank everyone

Hou to move the interruption vector table and make STM32F407VE work 32KB ahead.

I need 32KB of flash memory space to store data. As the smaller memory blocks are in the beginning, it sounded logical to use the first two blocks and move everything else 32KB forward.To achieve that I first edited the file STM32F407VE_FLASH.ld to c...

STM CUBE IEEE 1588-PTP drivers

Posted on May 07, 2018 at 20:15I cannot find PTP drivers in the CUBE software package. We have in house PTP stack developed which needs PTP driver interface. Does STM provide drivers for Ethernt PTP-module? It would be even great if STM can provide ...

PUTCHAR_PROTOTYPE question ?

Dear Members,Is it possible that I use two UART with  PUTCHAR_PROTOTYPE ?I have used UART3 with  PUTCHAR_PROTOTYPE for talking with PC,I want to use it as well for talking with modem (UART1)Thanks
