I want to send data on SPI3 via DMA in TIM2 ISR but something is wrong. The data sent is always 0. Can someone please have a look what I miss here? This example is made for STM32U5 Nucleo board with CubeMx.
Even though it is not really advertised as having changed a lot, it looks like the U5 increased the throughput of the PKA unit nearly 3 fold (upper L5, lower U5):Is this really the case or did the way of obtaining those numbers change in between (e.g...
Hello,I would like to measure the period of a square wave (around 1 kHz) with a timer in input capture configuration. I am using TIM5_CH3 on pin PA2 (nucleo G474RE).I would like to receive a bit of help in debugging my code since i am not able to mea...
Hi, I am a newbie in stm32. I am trying to receive DMA from USART1,USART2,USART3.But I am confused as how to do it because, all of them go inside same routine of DMA. Therefore how do I distinguish between different usart. my controller is stm32f103c...
Is there a way to programmatically exit from mute mode ? It seems that MMRQ can only be written to '1' to put USART in mute mode, but there isn't the possibility to return to a 'normal' behaviour by software. Any info to share ? Thanks
I have a programme running under Cube IDE. How can I run the MCU and its peripherals without powering up the ST-Link and its components on the DISCO board. Thanks for your help.
Hello,this used to work, but when I tried this project again, it doesn't work anymore... Not sure what happened, but I'm exploring what is wrong... I run xpack emulation that has own GDB server.I'm handling project under CubeIDE and I'm trying to con...
Hello, First time using the forum so apologies if I mess something up...Long story short I wanna get a microsecond delay, I know 2 ways of doing it:1) I can start a timer with default cube values and use a function like:void delay (uint16_t delay) {...
