Hello ST community,I'm currently working on a circuit utilizing an ATS240C-E Crystal with a 22pF capacitor for an STM32 microcontroller. I'm curious about the necessity and implications of including a Rext resistor in the output of the crystal oscill...
HiIs there any info available regarding source sink current of analog comparators on the STM32G4 series.The datasheet doesn't contain any info on this although the drive current of Opamps is mentioned as 500uA.TIA
In the Datasheet it says:"The VREF+ pin is double-bonded with VDDA on some packages. In these packages theinternal voltage reference buffer is not available."Does this implicitly mean all packages which do not explicitly have a VREF+ pin can not use ...
Hello.I am developing a system using STM32H7A3LIH6Q with CubeIDE.I use the SDRAM with IS42S16800J-6BLI,I am trying to use the BSP in the firmware package STM32Cude FW_H7 V1.10.0 as it is the same as STM32H7B3I-DK.I have a question here.In stm32h7b3i_...
I have purchased STM32F103c8t6 microcontrollers from three different vendors, but they are behaving differently.I am working on CAN, and on the microcontrollers from one vendor, it is working properly. But on the microcontrollers from other two vendo...
Hello,i have TFT with resolution 800x480 @ 24bpp connected to the STM32F767BIT6 with external SDRAM IS42S16400J-7TL.The MCU is running on 216MHz, thus FMC on 108MHz, SDRAM as CAS latency = 2 and LTDC pixel clock 19,2MHz(able to run on 24MHz too) with...
Hello everyone.I'm experiencing an issue with STM32CubeIDE. Everything worked fine until this morning when I installed the update to version 1.15. Now I cannot connect to any of my ST Links (3) which previously worked on my PC.I'm running Cube on my ...
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...
