Hello Community,I am using STM32H745 controller in one of my project.I am trying to send data from M4 core to M7 core using SRAM. To test the same I am increment a variable and writing to 0x10040004 location from M4 and reading the same location (als...
Hi,I am planning to implement DALI on STM32G MCU, I have looked at the documentation but all the example projects are with STM32L1 or STM32F1 and the library provided by STM is based on IAR workbench. My questions are Can I implement DALI Slave on ST...
I am troubling to write and read data from external SDRAM & NOR Flash in our custom made hardware which has STM32F429 controller.Thread is disconnecting while debugging & writing & reading operation not succeed.Can you please explain the all steps in...
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 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...
