erasing flash stm32f779ii

I'm trying to erase sectors 11,12 in the STM32F779II, I have been running into that problem for one week without a solution.So Right now I'm trying to check if there is ANY write protection on sectors 11,12. But There is NO write Protection error.How...

Is GPIO Ports RCC->AHBENR.IOPxEN required to be set to allow AF functions to operate.

Am trying to reduce the power consumption for STM32F0xx & G0xx applications.Reading the documentation it is not clear if I can disable a AHBENR.IOPxEN bit in the RCC blockonce a port is configured and still retain any GPIO port Alternate Functionalit...

SPI Rx double buffered DMA triggered from a GPIO

Using an STM32H743Zi I'm trying to receive 32bits of data from two SPI interfaces triggered at the same time from an external GPIO at a fairly high rate e.g. ~200kHz. Trying to use double buffered DMA receive.I started by trying to get an external GP...

Why the current measured form the microcontroller(Stm64 Nucleo L433RC- LPSleep mode) differ from the current value written in the datasheet?

I am using STM32L433RC -p microcontroller for current measurement. The current in the microcontroller was measured using X Nucleo LPM01A module.I was doing current measurement for Low Power Mode(Low Power Sleep Mode).The current value given in the da...

How can I use i2c to communicate two STM32F103

I want to i2c to communicate two STM32F103. one of them will be a slave and other will be master. But program is stop on this : void SendI2CByteData (I2C_TypeDef* I2Cx, uint8_t SlaveAddr, uint8_t Data){ __IO uint8_t temp = 0; I2C_GenerateSTART(I2Cx, ...

STM32F412 SPI DMA data bit-shifted

Hi.First of all, the essence of my problem is already described here - https://community.st.com/s/question/0D50X00009XkiXu/spi-dma-data-corruption?t=1567119350874In my case bug happens randomly and not very often. It could be one corrupted transactio...

Is STM32F103C6 can bus terminated?

I have two blackpill boards with STM32F103C6 MCU's on them, I want to explore using can bus between those two units and am wondering if I need to add termination to the cables or if those pins are internally terminated when configured for CAN.All the...
