Where can I find the relation between the OSPEEDR register different value (Low, Medium, High and Very High) and the frequency of the signals I want to use?

Hello ST Microelectronics community,I'm using a STM32H743ZI and I'm currently working on configurating properly the different I/O I want to use.To do so I need to set the set the pull up/down, open drain,etc. And also the speed mode.I could not find ...

STM32l073RZ dual boot, bank 2 not work.

Dear.I work with stm32l073RZ and I have a blinking led code and that code works on bank1, but it doesn't work on bank2. The strangest thing is that I also used the sample code for a flashing led from stmcubel0 and it worked. I think it may be because...

About the calibration of the ADC on STM32H747

I am currently trying on the linearity calibration and I am following the protocol (down below) but I do not understand where I am supposed to get the saved linearity correction factor bits[159:150] (step 3)? Every single ADC register is 32 bits at m...

STM32F412R HSI clock calibration with LSE

Hello,I'm looking for a way to calibrate HSI by using LSE. I've found some documents that describes the way. My situation is a little bit tough. I can't change PCB and I can't draw a way from LSE to TIM5 - channel 4. I'm looking for a way which will ...

I use STM32H735 and her backup memory at 0x3880_0000 (4KB). All works OK if I use SCB_CleanDCache_by_Addr(0x38800000, 4096) after a write. Is it possible to disable dcache in this area ?

I tried to configure MPU using standard configuration generated.I tried this codeMPU_Region_InitTypeDef MPU_InitStruct;   HAL_MPU_Disable();   /* Configure the MPU as Strongly ordered for not defined regions */ MPU_InitStruct.Enable = MPU_REGION_ENAB...

I Have a source code written with C++ Math Calculation(.cpp + .h files). I can run it on desktop by compilling .dll/ .exe or .OS. Is there any chance to compile or run this code on STM32F4 Discovery Board. What should ı have to do?

SCK Active during CS High

I'm making use of the STM32L433 and using SPI to communicate with a LLCC68 from Semtech.I've noticed that my SCK is active after my CS goes high.Is this normal behavior?Code Snippet for SPI Write:LLCC68_StatusTypeDef spiWrite(uint8_t* data, uint8_t s...

Hi There, I have the SMBUS example code for STM32L4R5ZI-Nucleo. As per the spec this code should be fully compatible with STM32L496z-Nucleo. However, when I flash the example FW from STM32L4R to STM32L496 the SMBUS functionality does not work.

STM32F070 Standby Mode (Not waking up...)

I wanted to test the wakup pin on the stm32f070f6.I have set pin PA0 to SYS_WAKUP1 and gave it the user name "WAKE". Before the user while loop I call: HAL_PWR_EnableWakeUpPin(WAKE_Pin); HAL_PWR_EnterSTANDBYMode();To enable wakeup (I thought) and put...
