copy float's binary content into uint32_t
Hello,I am trying to copy the content of a float variable with memcpy into uint32_t variable. unfortunately the binary content changes after copying. it should be 0xfff00000, like in the float variable. Does anyone know why this happens and how can I...
STM32H7B0 SWO over ITM doesn't work
Hi!I have a problem setting up Serial Wire Output over ITM. I followed every tutorial on the Internet (including this forum) and I still haven't made any progress. I run the MCU on 280 Mhz: In Pinout & Configuration -> DEBUG I configured Serial Wire ...

I am trying to do RTC wakeup interrupt using STM32L412RBT6 microcomtroller in baremetal c, but the interrupt is not firing, below mentioning my code.int main(void){ LedConfig(); Tim6Config(); RTC_ClockConfig(); RTC_Init(); /* Loop forever */ while(1...
SPI TXE or RXNE never goes to 1
helloI am using an STM32F7 series microcomputer.with SPI peripheralsIf writeable, write to the data register,After that, if it is readable, it is reading from the data register.The image in the code is like below,Writeable, readable loops infinitely ...
SPI Clock goes low when Cable Select does
Hello, I am interfacing with a peripheral where code exists for Arduino, but using it as reference for STM32. The SPI mode is 3. The Arduino code works, so I am attempting to reproduce it's methods for communication. An issue I am seeing is tha...
