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...
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...
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 ...
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...
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...
I'm using STM32F446, I found one issue. In STM32F4xx_hal_uart.c, it stated that. ============================================================================== ##### How to use this driver ##### ===========================================...
I build the whole program by the IDE. Following is my code. I can read the CID of the card without select the fatfs middleware. The program report FR_DISK_ERR in f_open. The f_mount works fine.int main(void) { /* USER CODE BEGIN 1 */ /* ...
