Posted on August 22, 2017 at 12:25The device is STM32F746NG-DISCO, and I measure the execution time of single instruction by this ways:int a=0; int b=255;while(b--) { a++; }make breakpoint and watch the value of States. And by this, I found that for...
Posted on August 20, 2017 at 21:37Hello! I'm using spi peripheral on STM32f042f6p6 and faced with strange situation: spi works only if system clock is PLL and HSE is PLL source. I have tried HSI, HSI48, with them spi does not work at all: neither tr...
Posted on November 09, 2015 at 05:13Hello, I am trying to use the STM32F4 HAL Drivers to read a 50 Hz PWM input signal and an A quad B encoder signal on an STM32F4 Discovery board, but the TIMx_CNT register is NOT incrementing on the external trigg...
Posted on August 22, 2017 at 10:37Hello!I am implementing a state machine which is driven by interrupts on the STM32F437IIT6.The interrupts occur as a result of using the HAL_SPI_Transmit_DMA() function.While testing my program i have noticed that w...
Posted on August 22, 2017 at 09:46We are using quite a few stm32 MCUs from 401 to 439, and our program becomes more and more complicated. In order to avoid possible deadloop, we have used watchdog to rescue the system, basically it is working well n...
Posted on August 22, 2017 at 09:07I need to restart my application without starting the bootloader or any reset (Watchdog, Soft-Reset,....).Processor: SMT32F207Bootloader start address is 0x08000000, application is starting at 0x08020000.The recomme...
Posted on September 18, 2015 at 23:30I have been working on porting code for a STM32F405 based board to a newer board that uses the STM32F446. I have been having troubles getting USB to work. See [DEAD LINK /public/STe2ecommunities/mcu/Lists/cortex_...

Posted on August 18, 2017 at 13:33Hello,I have an issue when trying to exit from standby power mode on the STM32F091CB MCU.I want to use 3 wake up pins (EWUP1, EWUP2, EWUP7 set in PWR_CSR register).One of this pins (EWUP2) is already high when enter...
Posted on August 21, 2017 at 06:48Hi.I would like to use FLASH Data(Write, Read, Erase) in Flash memory of STM32F301C8T6. I follow to an exampleSTM32Cube\Repository\STM32Cube_FW_F3_V1.9.0\Projects\STM32303C_EVAL\Examples\FLASH\FLASH_EraseProgram\MDK...
