Hello community, I experienced a strange behavior, when when using the UART-DMA-mechanism.The MCU is a STM32L051R6T6, and I use CubeIDE with HAL-drivers.I receive a cyclic telegram of 40 bytes on both USARTs.The telegram starts with two detection byt...
hi,We're using the STM32F7 in our project and would like to flash over USB. In the host application we use USB for data transfer which works well. Unfortunately, I have had no success getting the device into the bootloader as we have no access to the...
Hello?As title, I want to know product with USB, FD-CAN, 2~3 DAC, etc.Problem is USB and HCLK are bound(using external clock), so that upper limit is determined to be low.(48, 96, 144 MHz in maximum 170 MHz)For that reason, to ask the question, is ...
I have 2 I2S ports. I have a masterclock from an external source.My clock config is set for external 24.576Mhz I2S clock.I have set up I2S1 in half duplex slave mode for an ADC. It is receiving data in DMA.I have setup I2S2 in half duplex master mode...
I am using STMCubeIDE latest and an F411CE.I used the MX wizard to enable USB_Audio class device set to 48000 s/sI configured an I2S with master clock on IS2.It plays whether I start the circular DMA in the AUDIO_Init function or in the AUDIO_CMD_STA...
I'm working on Over the Air and I have three components.Bootloader in first two pages (using stm32f09x) and applicaiton and then second application.I'm unable to jump to application from bootloader for a specific reason.I have one linker script, gave...
I have created project USB Virtual Com Device on STM 32F407. I set size of parcel = 32 byte. When i send parcel and befor parcel ends byte will be "0" STM 32 don't read bytes after "0". If no "0" byte always is OK. What doe's it mean? How get full pa...
Hi,I am trying to read a simple register via SPI4, when I am using the HAL function (HAL_SPI_TransmitReceive()), this function return a timOut. I did some debugging and when I transmit my data via the SPI (line 1344) I can see on my RXDR the value of...
Hello, Is there a plan to offer Azure USBX programming training in the near future via MOOC? Thank you.
I have the B-L4S5I-IOT01A STM32L4S5 Discovery Kit. I followed the article and an online video to enable Tracex, but these are calling out a different platform. The RAM starting address for my kit is 0x20000000, but running the program I see in memory...
