I call this function a very large amount of times through out my entire program however in just one spot I reliably get a Hard Fault when it's called. When this line is executed, the fault occurs. (*hi2c->pBuffPtr++) = hi2c->Instance->RXDR;I called t...
Is there a "Cube-way" of making one-shot timed (RTC-alarm) wakeups from standby such that the RTC clock is not reset?
helloI am using stm32l4 series microcontroller with keil mdk arm 5 programing.Had successfully completed the booting process by manually setting boot0 pin and resetting the device using flash loader demo tool. Now i wanted to do the same without manu...
Hi all,I am currently learning how to interface with a USB using an stm32f2 as a host.I am using the fatfs library and it is working quite well.I have a question relating how removing a USB from the system. Similar to Windows for example, they have a...
Hello everybody,I'm not familiarized with hardware's industrial production. My question is about the serial (UART) built-in bootloader that comes with the Blue Pill development board. If I would like to create a new custom circuit, and print 10 test ...
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...
