Hello,We are using FMC interface.Is it that the access must be in the same size of the memory data bus ?In software, the bus width is defined as following:MemoryDataWidth = FMC_NORSRAM_MEM_BUS_WIDTH_16; and the access is 16 bit as following:So, is it...
Hello ST community,I have some troubles using Quad-SPI interface in STM32H7 micro.I need to communicate with a custom part using quad SPI mode (4 data lines). The interface is configured for indirect mode and DMA is enabled.In a super-simplified case...
I'm using a Nucleo-H437ZI2 board. Set up a simple project in STM32CubeIDE with the latest firmware for H7. I enabled both Icache and Dcache, no MPUI create a uint16_t array of 12,900 elements as a buffer for an ADC conversion using DMA transfer into ...
Hi. The stm32f103cbt6 processor in the debug section of the stm32f429 discovery card is burned. I have provided a new processor. where can I get the original debug code. thank you.
Hello, I am using NUCLEO-F429ZI. Can I use software to power off controller?Regards,
Whtat are major causes for emi emission. during emi test we are getting spike about 3db at 180Mhz, The product has wifi, sdram, spi flash. the mcu Stm32f446zej has 24Mh crystal and system core clock is 180Mhz.how to use Spread spectrum clock generato...
In AN4566 the maximum sampling rate of the DAC of a STM32F407 is claimed to be 10.5 Msps but I'm not able to get any faster than 7 Msps before it starts to skip samples.The clock of the STM32F407 is set to 168 MHz.TIM8 triggers the DAC via TRGO.DAC1 ...
Hello community,I am trying to use the capture feature on the comparator. I want to use it in low power mode. Right now I have something similar to the logic below:enable capture; //just to say that the capture interrupt is enabled here while(!capt...
Good afternoon,I have a stm32l432kc microcontroller on a custom board with two voltage supplies:1) A LiPo battery where I use a regulator to supply 3.3v to power everything and 2) A coin cell battery to only provide power to the RTC within the micro....
