SPI write data at rising and falling edge
Hallo,is it possible on any STM32U5 device to write only a SPI or other serial stream, that sends data on rising and falling edge?best regards

ADC DMA wrong reading right pins used
Hi ST community.I am in the process of building an audio recorder similar to the one in this video (12 bit ADC to Wav via FATFS and SDIO)(223) STM32 Audio Recorder 2: SD Card || SDIO and FatFs stack - YouTubeI followed the instructions of the follow...
Resolved! STM32F030F4 and STM32F103C4Tx CHİP BOOT
I use the STM32F103C4 and STM32F030F4 chip. I design a card with these chips. How I can programmable these chips? If I add SWDIO, SWCLK, +3.3V, and GND pins to the card as a male header, Can I connect the ST-LINK v3 to these pins and program it direc...
Resolved! STM32F401 Using flash memory sector 0 as storage
Hello,I'm searching for a way to use sector 0 as storage memory but no luck so far.I'm using STM32F401CCU6 and I'm working on a firmware which have to save about 300 bytes in a no volatile memory. For this microcontroller family we have this memory m...
STM32U5 USB CDC-ACM device gets into state where it fails to respond to device descriptor request
Hi,I'm trying to resolve a issue I see occasionnaly where my USB CDC-ACM device fails to be detected by Windows/Linux host as it is not responding to the first device descriptor request until the system is fully reset.The scenario:STM32U575 (can repr...
STM32H7 SPI Slave Dynamic Message Length
Hi,I'm using SPI to communicate between two micros - one F103 (master) and one H750 (slave). The data communicated will be vastly different in purpose and size (e.g. from simple requests to firmware image download) and so the designed protocol necess...
STM32U575 UART stops working if set wrong baud rate at first and then if set correct baud rate
I have configured the STM32U575 UART baud rate to 115200. I tried to send the data from external utility tool with baud rate 9600, since the baud rate is wrong, there won't be any communication.Now if try to change baudrate to 115200 then also commun...
Optimizing FIR Filter Multiply Accumulate
Hello,I am trying to optimize a function for a basic FIR filter on a STM32H743. This is the function:inline float_t FIRFilter(const float_t* inputBuffer, const float_t* firData, const uint16_t size, const uint16_t currentBufferIndex) { float_t outpu...
Different USB iProduct descriptors for DFU in different processors
Hello,We use a couple of different STM32's in our products and update them over USB via built-in the DFU bootloader.I noticed that:for a STM32G491, the iProduct descriptor reports "DFU in FS Mode"for a STM32F302, the iProduct descriptor reports "STM3...
Resolved! Stack LoRaWAN (STM32WLE5CC)
Hi,We are starting a LoRaWAN project here at the company and we are going to use the LSM110A module that has the STM32WLE5CC.I would like to know if you have a LoRaWAN stack for this ARM processor (STM32WLE5CC), or a video demonstrating how to start ...
