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...
Background of a problem:I am using ST low level libraries for USB OTG and USB HOST. I wrote my own USB class for ASIX USB-ETH adapter based on template and CDC class. The problem was that solution presented by ST driver was to slow. I could only send...
My APB1 Clock Frequency is 42Mhz.Init:hcan1.Instance = CAN1; hcan1.Init.TimeTriggeredMode = DISABLE; hcan1.Init.AutoBusOff = ENABLE; hcan1.Init.AutoWakeUp = DISABLE; hcan1.Init.AutoRetransmission = DISABLE; hcan1.Init.ReceiveFifoLocked = DISABLE; hca...
Hello,I have a PDM MEMS microphone that I am reading in I2S master receive mode. I am trying to take this data and put it in a FIFO buffer and then output the data over UART using DMA. I must be confusing the buffer sizes because I get mostly zeros...
I'm writting a very time-critical application for the STM32F334, where I have to control 4 power converters (mostly 3, one is time-shared another power converter). And recently I saw some ways to optimize code, like this://*********** 1360ns ********...
Hi everyone,How can I calculate cross power spectrum density by using cmsis dsp library with stm32f407 discovery board.
Hi all,I have a project for which we need as fast as possible drivers so we use as much as possible the LL drivers . Yet it seems that there was no implementation of LL for MDMA, even if it seems that all other DMA managers have theirs.Anyone knows w...
Hi there, I'm trying to make a basic USB audio speaker from an STM32H7 Nucleo board. I am fairly familiar with the USB audio middleware having studied it for a few days, but am not having much luck receiving audio data. I intend to use the built-in...
Hello! I'm working on project requaring CAN node. I decided to quckly check if the periphery is configured correcltly. For this purpose I connected two pull-ups resistors to Rx and Tx pins and tried to see some bits on the oscilloscope.I configured G...
Hello everyone, I have been learning to work with USB connection in STM32 and while my research I've noticed that some schematics have D+ line pulled up to +5V, when in stm32 dev board schematics and in AN4879 it's pulled up to 3.3V and that's what I...
Good morning,I am trying to develop a touch screen screen controled by a STM32F1 and connected to a PC throught USB port.My doubts are related with the USB comunicationI've found many examples for USB comunication as Virtual COM or as a Mouse/Joystic...
