I would like to write and read into the EEPROM of the STM32F407 Discovery, but I can't figure out which section of the Reference Manual to look at.First of all, is there an EEPROM on the F407 Discover?If so, in which section/document can I find it?Sh...
We are using STM32U575VGT6 and declared some variables in SRAM4 region of MCU. But not able to see the values in watch or memory view of IAR IDE.Debug further and found that STM32U5xxxG.ddf file do not define address zones for SRAM4 region.If we add ...
We are planning a circuit were one PCB needs to be charged from another one. The first will have some capacitors whereas the second has a battery. This means the charging should be as power conscious as possible. We tried to find out what the consump...

I found some bugs in the CubeMX generated code.Does it forget reset the `state` after SDIO DMA TX? when I query the TX state by `HAL_SD_GetState` always get wrong result. Dose SDIO DMA mode forget clear the transition state to SD card? when erase the...
I have STM32F407VG board and it has error in flashing time see screen. I have STM32F407VG board, and it has error in flashing time see screen. Yesterday was everything ok but today is broken, I don't know why!I found a solution https://community.st.c...
This is the first time I have used an STM32F4 board.In the Discovery kit with STM32F407VG MCU I see "one digital microphone", but I don't understand if it's already integrated in the board or I have to buy it separately.If it is included, can you tel...

Hi, i'm trying to read voltage through voltage divider circuit, o/p voltage is 3.2, but i could read only around 2.7, can some help whats wrong with the codenote: R1=6.8K ohm and R2=12K ohm.im attaching circuit and code. HAL_GPIO_WritePin(GPIOB, GPIO...
I need help in implementing a solution. I'd like to implement a system that measures elapsed time (ET) between two digital input (DI) pulses. These two signals will be on different channels. There are 4 sets of signal, therefore I need to measure fou...
