Resolved! Why is there no implementation of Low Level drivers for MDMA on STM32H7xx.
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...
Resolved! STM32H7 USB audio difficulties
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...
How to quckly test CAN module using SPL?
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...
To what voltage should the D+ line be pulled up when designing USB connection in STM32? +5V or +3.3V? All documentation and dev board scematics says it's 3.3V, but it didn't work.
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...
Touch screen USB STM32F1 example
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...
Custom HID Device (Joystick)
Hi there,I have an old joystick which i want to convert to a custom hid device, the stick has three shiftin registers (cd4201) which i am reading using spi1. I know these shift register are being read cause i am sending it to serialport3 (just for de...
Resolved! HAL_FLASHEx_Erase does not work for STM32L496VE due to incorrect FLASH_BANK_SIZE and FLASH_BANK_2 being declared
We have designed a custom bootloader solution that works on multiple STM32 devices, however when we attempted to use it on STM32L496VE we realised HAL_FLASHEx_Erase did not clear the flash, even though it returned HAL_OK.On further investigation, it ...
How to enable pdm2pcm middleware?
STM32F4-DISCOVERY board: I need to read from the mic (MP45DT02) and I was trying to use the STM32CubeIDE to generate the initialization and I cannot get to enable the pdm2pcm middleware. I have tried to configure I2S2 (no errors) but still pcm2pcm is...
stm32f407 - timer10 interrupt handler called with delay
Dear ST community,I am running stm32f4-7 with FreeRTOS, and lwip, I am running TCP server by use of LWIP and some other application logic. I need to generate PPM signal (8 PWM pulses with different length) every 20ms. For this purpose I am using time...
