STM32 MCUs Products

I would like to know To configure the I2C bus of STM32F439 in receive and transmit mode, which bit must be Set/Reset and in which register it is located, and how it is append to the Address byte...Thanks

STM32Cube SPI interrupt example project does not work on STM32H743 ?

In order to investigate the SPI issues on my own setup (based on STM32H743 Nucleos) I gave a try to the SPI example project in STM32Cube 1.4 (SPI_FullDuplex_ComIT). Compiled and debugged with Keil 5.28.In this example project Slave and Master exchang...

Where can I find typical DNL and INL error profiles (X axes would be Vin and Y axes the error in LSB) for STM32L0 12 bits ADC, ideally with and without HW oversampling.

SDRAM configuration for 216MHz sysclk.

Hello, with a STM32F7508-DK board, all examples using SDRAM have the sysclk to 200MHz, therefore the FMC clock to 100MHz.I am trying to enable sysclk = 216MHz, and FMC = 108MHz, so I followed the SDRAM user manual, and configured the following settin...

STM32L4 External SRAM problem

HiI am working with a STM32L496G_Discovery board and Cube IDEI am having problems with the external ram. I have called BSP_SRAM_Init();and defined an array in that ram spacefloat testInput[TEST_LENGTH_SAMPLES] __attribute__((section("._myvars")));In ...

Problems using full-duplex spi with DMA and STM32F4 as slave after 10 cycles.

Hi,I am trying to comunicate raspberry pi (master) and stm32f4 (slave) trough spi with dma. I am using HAL_SPI_TransmitReceive_DMA. The comunication seem is working fine but time to time (when 10/8/6data has been receive/trasnmit +-) my stm32 trasmi...

Division by zero exception flag not set in STM32H7 FPU

I'm digging into the FPU of a STM32H743 (Nucleo board, Keil IDE).I've checked that the FPU is enabled in register CPACR.I've compiled the following dumb code:volatile double test = 0;   test = 1.0 / test;If I look at the assembly I've got:VDIV.F64 d0...
