Posted on February 11, 2016 at 17:24Hi, I've tried to upgrade the firmware via DfuSe Demo, but it hungAfter this, I've discovered that my STEVAL-MKI109V1 board has bricked.I can flash it again using a Nucleo Board's embedded STLink. I could test it ...

Posted on November 23, 2017 at 13:11As the datasheet says, PC13 is used for RTC_TAMP1/RTC_TS/RTC_OUT/WKUP2, and you said previously that you are using the RTC. Try to enable the pull-down on this pin.

Posted on November 09, 2017 at 14:43You could use the BSRR register:while(1){ GPIOC->BSRR= (1 << 9); // Set bit 9 GPIOC->BSRR = (1 << (9+16)); // Reset bit 9}Another way to optimize is the use of bit-banding, because it doesn't affect another pins...

Posted on October 13, 2017 at 15:37You need to read 3 documents:- The specific Datasheet of the STM32 processor. Here you will understand the memory layout of the registers.- The Reference Manual for the family of the processor. Then you will see bi...

Posted on February 23, 2016 at 21:12I'm not sure, but maybe a solution is to drive the Vdd_IO pin low when using the SPI bus to communicate with the EEPROM. It's up to someone from ST to answer if it's reasonable.
