Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I'm using the L4xx HAL library and trying to set my SPI RX threshold value to 1/4 so I can receive a single byte response. From my research there should be a HAL function called SPI_RxFIFOThresholdConfig that will do this. When I put it into my SPI i...
Good morning,I have a problem sharing a variable between bootloader and application into my STM32F303ret6 uC. I need to write a shared variable to tell the bootloader that it has to wait for new firmware.I read many posts which suggest to declare a v...
I need to establish an Ethernet connection between two embedded devices. From a PC I can connect to my application or to the other device and exchange messages. How do I do this on my H750. How do I open a connection from my device if the IP and port...
i found in Cube/FW-packs some Audio class Device examples, but no one with Audio Host.i selected in Cube for H743 USB_HOST and Audio_Class, ok .and now : how to "play" on connected sound card ?
Hello, I have a STM32 Nucleo-64 development board with the STM32L476RG MCU on it.. I have made a small PCB that, among other things, brings the USB interface to a connector. I have implemented a simple USB configuration following some online tutorial...
The officially recommended recipe for lwIP on STM32H7 puts the ethernet DMA descriptors in SRAM1. SRAM1 is not zero'd by the default startup code.It's unsafe for the network drivers to assume that buffers and critical data structures live in .bss.F...
HiI found something strange in cmsis dsp source.I am using stm32f429 and LITTLE ENDIAN and cmsis dsp library V.1.5.1.in cmsis dsp library(arm_mult_q31.c) :void arm_mult_q31( q31_t * pSrcA, q31_t * pSrcB, q31_t * pDst, uint32_t blockSize){... whil...
I have found several other forum posts on this subject, and I've tried to follow them, but I'm still stuck. For some reason, SPI3 on my bl47eio1a never enters a ready state. It gets stuck waiting for a ready state before it ever can send or receive a...
Hello, I'm able to connect the STM32CubeMonitor-UCPD with NUCLEO-G071RB and X-NUCLEO-SNK1M after following the instructions in AN5418. I only changed port 0 Sink PDO1 to 0x020641F4.I want to use the setup as a sink and always want to get the maximum ...
