I am planning to pre-program the flash memory of STM32 for production, how will the reflow oven affect the data retention of the flash memory? According to the datasheet the data retention is specified to 15 years @85°C and 1kcycles. Thanks!

Flashing a HEX file in STM32F4

Hi forum.. I developed a bootloader for flashing a hex file present in usb key. The text from the usb key is transferred via UART to another micro.. The bytes are then flashedin the flash area.. You can find the HEX file in the usb key here ..When I ...

Resolved! Hi, i am checking IPMB Supported MCU(MMC) Which should able to communicate with BMC Please advice

Resolved! What does 'Value Line' stand for? What is the difference to the 'non Value Line' devices?

Several MCU are described with the label 'value line' but I could not find an explanation what that mean. I assume it is related to a system architecture, right?

Hi folks.. I did a bootloader for the STM32F4 microcontroller.. I read a text file and I flash the bytes.. i really don't understand the following parts of the HEX file ,.. :020000040800F2 :040000050800ACB98A The other parts of the fix are addre...

Resolved! Hello Everyone, Please is it possible to trigger an adc conversion in DMA mode using external interrupt from gpio pin . I am using stm32f303re.

Where can I get the supply of STM32F407VGT6 in China? My company is facing bankruptcy due to lack of stock. Please help me! Thanks a lot! ! !

How can I measure encoder velocities using pulse width measurements (low RPM)?

Hi,I am using the STM32F303RBTx MCU and currently have a quadrature (4x) encoder set up on TIM2. You can find my STM32CubeMX configuration settings below: I would like to implement a tachometer for this encoder. I am aware of the method of periodical...

STM32G474 boots with FPU enabled when BFB2=1

We are using the STM32G474 MCU in dual-bank mode. In the options registers we have DBANK=1 and BFB2=0 or 1 depending on which bank we are booting from at the moment (we swap banks during firmware updates). We have found that when booting and BFB2=0 t...

Resolved! 32F0308DISCOVERY is Obsolete, is there a replacement that is compatible to the replacement board ? I already use 32F0308DISCOVERY but needed to buy an up to date replacement. Thanks.
