When writing to RTC and then reading back, my year is always off - writing 18 gives me back 21. Tried adding delays up to a second between instructions, no joy. Using Cube and MDK, RTC is running LSE 32768 and works fine otherwise. Both read and writ...
I need to transfer data between two micro controllers - both short commands and large blocks of data.The STM will receive and so will be the SPI slave. I intend to use DMA.The SPI master will transmit either short or long packets and so need a way to...
I'm using STM32CubeMX Version 5.0.0 and am trying to get the WWDG (Windowed Watchdog) working on a F7 series MCU.The STM32Cube code did not appear to function. It only initialized the WWDG, but nothing more. I searched online and found that others we...
Hi, I have being trying for weeks now to get PTP timestamps with no much luck.Q1. Is there any example code available? The user manual (en.DM00314099.pdf) is rather confusing.For example in 57.9.7 Programming guidelines for IEEE 1588 timestamping it ...
I receive some data from a terminal. Say I send 1234 on the terminal.I set a break point onvoid EP3_OUT_Callback(void){ packet_receive = 1; Receive_length = GetEPRxCount(ENDP3); PMAToUserBufferCopy((unsigned char*)Receive_Buffer, ENDP3_RXADDR, Receiv...
Hello friends.I try imeplement freemodbus on my project. And I have a problem with connect. My task is here:/* ------------------------ Defines --------------------------------------- */ #define REG_INPUT_START 1000 #define REG_INPUT_NREGS ...
I am looking at the code here that has the algorithm for producing the device serial number reported when the MCU is in USB DFU mode.https://github.com/libopencm3/libopencm3/blob/master/lib/stm32/desig.cThe document they reference there, https://my.s...
I want to forward all data received at the VCP with USB FS to UART how can i implement this specific in code?I have been searching for long time for this and i have not found any good example of it.Can you please help me?Until now i am doing this lik...
How can i forward data which i received at my COM Port via USB FS to a UART of my Choice?I already send data to UART5 and i measured it with an osci and its workinghar buffer[] = "TEST"; HAL_UART_Transmit(&huart5, buffer, sizeof(buffer), HAL_MAX_DELA...
Hi there.I'm trying to set up my NVIC but I'm not able to understand how they work.I'm using two timers, GPIO and UART. I used the function HAL_NVIC_SetPriority and set the next priorities:TIM 1 -> (Preempt: 0, sub: 0)TIM2 -> (Preempt: 1, sub: 0)UART...
