STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi everyone,I expected to get a faster multiplication processing using the arm_mult_f32 function than a normal multiplication like val1*val2. However, when I tested it using the SysTick->VAL I get a bigger processing time for the arm_mult_f32 functio...
Hello,I'm new to all this, first-year uni student and still learning java. I'm working on someone else's code for the uni motorsport club in c++ and the original coder has left.Currently, we detect the wheel speed using a hall effect sensor and captu...
Hello,I connected my STM32 board and it's blinking.However, I get "Found 0 stlink programmers" when I run st-info --probeI am running Catalina 10.15.2.Would anyone know how to resolve this? I looked for info/drivers but did not find anything.st-info ...
I have a master Node with NEC MCU (https://www.manualslib.com/manual/109966/Nec-Pd78052.html?page=289) which commincates with a slightly modified I2C protocol called SBI. I would like to make a SLAVE node, which communicates with the above mentioned ...
Can LPTIM1 be used to wake the STM32H7 from CSTOPoperating mode?From RM0455 the "RCC APB1 low-sleep clock register (RCC_APB1LLPENR" has the following bit: However the above mentions CSLEEP, not CSTOP which is a lower power operating mode.I think I ca...
I started getting this message when I try to debug my code. However, there are currently no breakpoints in my code at all. I have gotten this in the past and I deleted and redownloaded the IDE which I really do not want to do again. I am running i...
I am using the Cube IDE to put the STM32H723VET into standby (which to my knowledge is the lowest power consumption). The code below is what I use, I just want to make sure this is doing things correctly and I haven't missed any settings or anything...
Hello,I'm struggeling a bit in understanding the whole features of possible RTC improvements. General information, right now I'm using a STM32L051 and a external 32,768kHz Oscillator for the RTC. It's working in general, but the OSC has +/-30ppm whic...
Hello,We are using STM32G431KBU6, and we would like to incorporate Hardware SSI, i.e. send data via DMA, or at least send every 32 bit chunk via DMA.So far we were only able to do implement Software SSI (an interrupt per host clock).Your advice is ap...
