hi, I'm trying to do the FFT using the CMSIS DSP V1.15.0 libraries but I get a graph with random frequencies...I have a CM4 microcontroller(without FPU) I implement the below code and get random frequencies.I test the same code on a CM7 microcontroll...
Hi,I have a question regarding the possibilities and best practises of the early wake interrupt generated by the window watchdog.Is it possible to use the EWI to refresh the watchdog? And if so, is it actually a good idea and reliable?To describe the...
Hi there, I am working on a project using the STM32H755 zi that has 1 USBC port, can we use the same port for uploading the code, UART Communication and powering the device instead of using ST-LINK? Or is there any way to use ST-LINK for communicatio...
Hello, I'm using the STM32F469NiH6 to try and do a certain number of SPI transactions (let's say 12 bytes) at regular intervals without core intervention, using Timers and DMA. And I have a couple of questions concerning this (I have had a look into ...
I set up EXTI so I get interupt on the correct pin GPIO B.6. But I cannot get it to wake up from stop1 mode. I call WFI and RTC wakes upp the processor regularly but EXTI will not. Reading the reference manuel it says any interupt should wake the pro...
I already installed the latest stm32cubeIDE(version 1.15.0).when I was trying to create a new stm32 project, the error present as below:So I want to install install software package first, but the help->manage embedded software package is no response...
Hi,Master:Question：When the finished product cannot be debugged with jlink, I want to save and trace the function stack information through the firmware. When there are some accidental exceptions, I need to use the function stack to more delicately l...
Hello all,I am attempting to read the direction bit and have observed a surprising behaviour. Let’s say my encoder was set to the reverse direction. If I attempt to move the encoder in the opposite direction, the direction bit doesn’t update until I ...
I could cry... ("rrrr", the more I dive into latest STM MCUs - the more I get frustrated - LOL)The datasheet for STM32U5A5, LQFP64 package, tells me: there are PB15 as SAI2_SD_A and also PC12 as SAI2_SD_B.But the CubeMX does not let me configure thes...
Hi ST,i have an inverter project designed with stm32g474xx and there is a "h-bridge" topology in the system.Can I create a uni-polar PWM to get three-level output while controlling this topology with hrtim1?Can hrtim1 create uni-polar pwm outputs (18...
