Hi,I am using a STM32H5 as SPI slave DMA (the main clock is at 250Mhz and SPI clock is at 160Mhz)... I am trying to receive data (2072 Bytes) from a master with a clock of 4Mhz and I am having some OVVERUN is this normal. When the master clock is at ...
I have STM32G070RBT6, a timer is set to give interrupt every 1 second, in interrupt i am incrementing a variable timer_var1 then in main file while loop i am dividing this by 10 and assigning this value to another variable TIMER_NOW. Now when timer_v...
Hello everybody,I try to get canbus communication on the blue pill+ under zephyr to work. I use the canopennode sample. I got the following overlay: / { model = "STM32 Minimum Development Board (Blue)"; compatible = "stm32_min_dev_blu...
Hi there,I have been using STM32 nearly 10 years.I did modification according to company requirements. But it doesn't mean I am very good at C,C++ or else. I understand coding if it'd in C or C++ format. I understand mathematics, logics and conditio...
I've seen other posts to resolve the compiler warning of "elf has a LOAD segment with RWX permissions", but I'm receiving this warning only when calling functions in RAM using the .RamFunc segment attribute. From the map file I've verified the functi...
Is it possible to use UART3 as the bootloader interface on this chip?I’m able to communicate with UART3 (so the hardware connection seems fine), but I’m unsure about the baud rate—does the bootloader autodetect it, or is it fixed? The bootloader work...
Posted on October 16, 2014 at 14:31Hi everybody!I'm going to use STM32f429 with external SDRAM (IS42S16400J 64MBit) in my project. I'm trying to make FFT for 32768 input buffer, my function calculate it in about 250ms.Functions in CMSIS LIB do it mu...
I am designing a board based around the STM32F030RC, and noticed an apparent discrepancy on IRQ18 between materials.STM32CubeMX allows both TIM6 and TIM7 to generate interrupts, and the stm32f030xc.h file it generates defines TIM6 as IRQ17 and TIM7 a...
hi everyone,Does stm32 have any ptp integration manual? For example, I would like to use a DP83640 with an integrated ieee1588. And this phy contains PTP/SFD interrupt pins. Are there any pins in stm32h7 family or stm32f7 family for this interrupt? O...
I am developing a application for Battery based 4G GATEWAY so most of the time I want my micro-controller in sleep mode.I am using Standby Mode as I require least power consumption.The requirement I need is I want to wake micro-controller at specific...
