Problem with TIM1 configuration of STM32F303CD

Hi, I want to configure my TIM1 to use it for driving a bldc motor. I have made several configuration in the registers, but it won't work. TIM1_CR1bits.CEN = 0; //Timer enable TIM1_CR1bits.DIR_= 0; TIM1_CR1bits.CMS = 0b01; TIM1_...

How to get the STM32F7 CAN peripheral out of passive mode

I have several slave devices devices hanging off connected to an STM32F7. When I power cycle the slave devices, the REC field in the ESR is greater than 128, causing the EPBF bit (in passive mode) to also be set. If I reload the chip, ESR is cleare...

Please give some help on L1 cache and MPU

Hello,I am working with STM32H7, Nucleo board and Atollic TrueStudio. I have a test routine processing an array of data that is in flash, test routine is also in flash. Around it I set and clear a portbit and measure execution time. Now I wanted to s...

PDR/POR reset once shortly after startup

Posting here as accidentally posted under wrong topic and was deleted...I am using an STM32F429 on a custom board. The chip is resetting once shortly after starting up, around 10 secs. I put this code at the beginning of the main function: if (__HA...

STM32R9x support HyperRAM/HyperFLASH 1.8V?

RTC Time is not incorrect randomly after the MCU is waked up from Standby mde

Hi ST team,I was coding on STM32L431 chip and got a problem about the RTC time.The problem is that the RTC time is not synchronized with my input randomly after the MCU is waked up from Standby mode. The following descriptions are the detail.[Reprodu...

Posted on November 10, 2013 at 07:51Is it possible to decode a mpeg4 file in stm32f407 .at least 15 fps & 320x240 pixels.till now  i can decode jpeg pics quite fast . if its possible is there any open source library to do this?i have looked at ffmpe...

Create a position independent executable (firmware image) that can be run from more than 1 location in flash?

Hi,I'm currently developing an application on a STM32F103 MCU that is capable of upgrading its own firmware over CAN. The flash memory is split into 2 partitions and the when the currently active application receives a FW update it copies it into the...

TIM2 exact timebase settings

Dear all,I'm using the STEVAL-PCC009V2 based on a STM32F103RBT6 microcontroller, set to work with an internal clock frequency equal to 72 MHz so CK_INT = 72 MHz (refer to figure 100 of RM0008 Rev. 19, pag. 367/1132).I need to obtain a 10 ms time base...
