I need to configure the system clock using registers for 48mhz without external crystal, I already have it configured and tested with stmcube ide manager, but I need to decrease the flash memory and ram, as they are critical.i have this configuration...
I tried to redirect printf function to SWV. At first, I was not successful at doing so, until with some modifications and conditions it is working now:The core clock is 280 MHz but I have to set the core clock to 140 MHz in SWV configuration of CubeI...

The following document explains the DSP library for STM32F10x which contains the functions for the PID controller, is it compatible with STM32G474RE? If not, would you please guide me about its implementation on a microcontroller? https://community.s...
100khz Oscillator for LSE input. The OSCillator works right bcz I test the waveform by scope.but stm32h7b0vb cannot get lserdy bit set.Seems I m the 1st Person meet the situation.plz help me. Thanks.
HELLO EVERBODY i want to test the canfd communication on my nuclue-h753 in normal mode, my goal is to transmit data from canbus1 and receive it on canbus2 and vicaversa i configured both CANFD1 AND CANFD2 on the board with classic can configuration ...
Hi there,I'm using DMA to circular sample ADC channels. I'm getting the ADC complete interrupt - its all good. The question is, how do I set the sampling rate of the DMA, let's say that I need those samples every 2 milisec - how to I set the DMA to p...
I'm completely baffled as to how to make DMA and sleep mode work together on an STM32F0. I presume though that the issue is not family specific. It appears when the CPU enters sleep mode via the WFI instruction, DMA stops working. If a busy loop is u...
For whatever reason, I can't delete this post. It is closed, see resolution below.--------------------------Hello. We made a board that powers the VBAT pin of a STM32L431RCT6 directly from a coin cell battery. The LSE and RTC work well. But we reali...
I want to make i2c monitor that can read data sent by slave with specific address (0x42). So monitor has to capture sequence of1. Start2. Slave address (write)3. Command byte 4. Repeated start 5. Slave address (read)And then start reading actual dat...
