Hi,I am porting an application from the STMF429ZI to the STMH753ZI and have noticed that the STMH753 is slower when reading the GPIO inputs compared to the STMF429. In one function, multiple GPIOs are read to gather 16 input states. Measuring this fu...
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...
