Hi everyone;I have select;In cube mx -> middleware and software packs -> X Cube Algobuild -> DSP LibraryHowever , there is no dsp libraries in my keil project.And there is no .lib in the folder.I have re-generate for several times, but it did not tak...
HiI am working on project that receive several I2S streams from MEMS microphones. I found that "audio level" from second microphones pair had higher level then from other. After some analysis and SD lines swapping i found that I2S data received by se...
Hello, I configured CAN communication between two STM32F446RE boards. The code works in Loopback Mode, but not in Normal Mode. I did not use an external CAN transceiver, as I read that direct communication is possible on the STM32F446RE. What I have ...
Hello,I want to use a STM32H7S3 at 1V8 but was wondering whether I could still use VDDA at 3V3 in order to be able to use the internal voltage reference. I know that this was impossible on a lot of older MCUs, but I can't find any information which p...
I have an STM32L452 rigged to use an external clock so we can keep the RTC running. Schematic attached.X2 is a clock from SiTime, programmed to be 32.768kHz. C36 is a supercap acting as battery backup. I used STMCube to generate the startup code to f...
Hi, I'm new to this, so bare with me :) I'm following the UM2421 - getting startet guide for the P-NUCLEO-IOM01M1, and everytime I connect the USB to my PC, I get the FAIL.txt where it says: The interface firmware FAILED to reset/halt the target MCU....
Hi, Currently we have received our first prototype batch of board with the STM32H7S7Z8J6. There is external flash and ram on the board also, but first we want to try a simple test where we will just use the LTDC interface without touchgfx to make the...
Hi, when configuring the Lora stack it requires RTC in free running mode along with some alarms. I am looking for ways in which I can get epoch time in my application layer. Thank you for any comments on thisRegards
It only gives the bit and the description: Bit 22 HDRXGNEQEN: Enable HS Rx gain equalizer 0: Disable the gain equalizer 1: Enable the gain equalizer But what does it actually do? When would you want to use it? Thanks
Hi,I am using STM32H563ZI to design a new product, there is a SDRAM(W9825G6KH-6) connected to the MCU with 16bit width bus. The SDCLK is 125MHz while the MCU running at 250MHz. The read and write to SDRAM address space are both OK. But the read writ...
