Greetings,I am working on a Firmware OTA module for STM32L4 series and for that I need a module to write the firmware into the internal flash memory since system bootloader is not available when RDP is enabled. I was wondering if there is already a m...
This is an example of what I try to do with the DFSDM without success.I want to apply a low pass filter with a frequency X to a square wave that I have sampled at 44100Khz with 1024 samples and that I have stored in an array (input), the result I wil...
Hey everyone. I am working on a project where I am attempting to detect a frequency of a signal using autocorrelation. I am doing this through applying FFTs and IFFTs. Basically, I have been running into some issues trying to get the correct function...
I am using the STM32F746 board and trying to program the microcontroller. However, the STM32Cube IDE software is showing an error, as shown in the figure. The "stlink_USB" and "5V" are connected.
Hello dear community,I’m working on a USB sound interface, using a STM32F7 and an external DAC chip offering 8 stereo output channels.Most of the DAC are offering multiple serial data inputs ports. For example, the Analog Device ADAU1966A is offering...
I have a use case for communicating with the SDRAM chip onboard the STM32G474E-EVAL1 board. Took a look at the board schematic https://www.st.com/resource/en/schematic_pack/mb1397-g474e-b04_schematic.pdf and an example project that came with the STM...
I am trying to use the HRTIM peripheral on the STM32Hh753VI as a PWM generator with variable duty cycle. I want to use Timer B1 on pin PC8.Firstly, I tried using Simple HAL functions:HAL_HRTIM_SimplePWMStart(&hhrtim, HRTIM_TIMERINDEX_TIMER_B, HRTIM_O...
I'm using a STM32H745 and running a bootloader on the CM4. In the bootloader I want to set the boot address of the CM7 using the user option bytes. Is this possible and if so, how should I do this?Kind regards
I have an STM32H563 communicating on I2C4 @ 1 MHz (fast-mode plus) to an I/O expander with no problem. However when I add a temp sensor (TI TMP175) to the same bus, communication doesn't work for the TMP175. The TMP175 communicates > 400 KHz only if ...
I am trying to set alarm canitnously in loop every 4min.But it is working only 5 time.Is there any way to set alarm cantinously after every 4 min.
