IWDG of STM32F103 work in hardware watchdog mode, by set MCU's option bytes.My question is "Once the option byte wrote, software need not start the IWDG by code, even after many times reset ( include software reset , PVD reset, IWDG reset) IWDG is ...
Posted on March 15, 2018 at 11:03Hello there, Using the BSP example code I have composed a function for reading data from an external QSPI flash memory. Here it is: https://pastebin.com/ZsGjfDGD I am facing a peculiar problem at the moment. When I r...
I wanna my design can back to working after EMC shocks.So I plan to use Hardware watchdog , with followed code under ucOS*************************** usrOption = FLASH_GetUserOptionByte(); if( (usrOption&OB_IWDG_SW) != 0) { FLASH_Unlock(); FLASH_Er...
I am using an STM32F429FI Nucleo board, and not able to communicate over UART with the confiiguration having 0.5 Stop bits and DMA being enabled.Is this a valid configuration? Data sheet suggests use of 0.5 Stop bits with SmartCard mode does it mean ...
