Hi. We found a serious problem in the behavior of the memory bus pins during reset.Our design uses an STM32H743I CPU and non-volatile MRAM/FRAM memory connected via a bus. We use the FMC controller to access the memory, the bus pins are set up, and ...
Hi,Can I connect a 32bit bus SDRAM to STM32H7 and assign the FMC IOs as I wish or should I stick with the Alternate functions of the GPIOs?Specifically: can I map 32 GPIOs to STM32H7 models with 144 LQFP package where the GPIO for D31, D30 etc.... (...
Hi I have an SD card working on a Nucleo-F439 board, but I can’t get it to work on the Nucleo-H729. I'm using the code from https://deepbluembedded.com/stm32-sd-card-spi-fatfs-tutorial-examples/, but I receive no response on the SPI interface during ...
How can i do the integrity check for flash and RAM in STM32H735?.Please guide me.
Hello.Is it possible to reset the product state from closed to openinternaly by the firmware on a STM32H563?Can i do this easy by rewriting the ProductState to 0xED, or do i need additional provision information or the provisioning password to do thi...
Besides, I don't know whether this configuration of MX is correct. /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_GPDMA1_Init(); MX_SPI2_Init(); MX_ICACHE_Init(); MX_I2C1_Init(); MX_RTC_Init(); /* USER CODE BEGIN 2 */ ...
The STM32H743 datasheet section 3.3.2 states that the TCM memories are zero wait state, implying that they run at the core speed of up to 480MHz. It does not make any claim about the rest of the SRAM. Figure 2 in the datasheet shows all the AXI and...
Hello,I am trying to update some code to use UART with DMA for receiving instead of the polling method.I want the implementation to work for messages of unknown length so I use the HAL_UARTEx_ReceiveToIdle_DMA function.I know that the maximum message...
Dear,Setup:We using a STM32H7B0 100pins.We use 1 ADC input at 1M samplesConfigured as 16bit, differential input, with an offset of 32768.We use a Vref of 2.5V.The other side of the differential input is 1/2 of Vref (buffered with a opamp)To sample th...
I just bought stm32 and i cant find any guides how can i enable led. I flashed pin PB7 so that it would output current
