Dear Sir.we have some identical boards based on STM32U585 . The RTC is configured to produce 32.768 KHZ at pin PA8.On one board the same code will not pass the code will not pass the /* Wait till LSE is ready */ while (READ_BIT(RCC->BDCR, RCC_BDC...
I am getting this following error while trying to debug the Custom Board.please help me find out what is the meaning of this error.Thread #1 [main] 1 [core: 0] (Suspended : Signal : SIGTRAP:Trace/breakpoint trap) 0x1fff5a30 <signal handler called>(...
What is the correct Vhys parameters for STM32F2xxx MCU I/O ports?It looks like as wrong datasheet values here (DS6329 Rev 18): https://www.st.com/resource/en/datasheet/stm32f207vg.pdf#page=102The published values are too big.Please double check the c...
I want to connect my MCU with a module which has a specific way of communication. Module sends messages of variable number of characters, where period between two characters is also variable. My idea is to use timer in order to overcome this problem....
Greetings!I am working STM32F691 . I want to flash images to QSPI flash memory without using tftp . Requesting you to kindly help us with procedure/steps for the same.Thanks in advance
I am using FMC on STM32F765NIH7. Using the HAL library for FMC, which copies the data byte by byte into the NAND register, what happens is that almost any interruption during the data exchange can lead to incorrect receipt of them. So that interrupts...
I have fail using multi UART while using with the ring buffer,but using the HAL function testmulti uart is fine,i using the Keil c(MDK) complier check and i test if cnacel the HAL_UART_Init(&huart3) or other one is fine ,and i look for other of the s...
Hi,I would like to know about the STM32F091's RTC accuracy and frequency error information.Is the RTC accuracy or frequency error factor affected only by crystal?Is the RTC accuracy or frequency error factor affected by MCU itself?Is it any ST docum...
Hello, I am using Nucleo-H743ZI ,I am using timer1 to trigger ADC.My APB1 clock frequency is 240MHz and my ARR register is 240 of timer 1. So my sampling rate of ADC should be 1Msamples/sec. To check it I am toggling a pin whenever ADC conver...
