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...
STM32F730 and STM32F722, might be more other variants updated usb hs otg register map, added ULPISEL bit in OTG_GUSBCFG register. However, it is not going to be set when choosing external hs phy in cubemx. The problem causes external phy not working ...
Hello everyone,I started working with my Nucleo yesterday and made some CDC app (programming with on-board ST-link USB and using on-board User USB to check if it's showing in Windows device manager). I am quite sure it was there each time I plugged t...
I am trying to set up an STM32F412VE chip using the DFSDM peripheral to read from a PDM microphone.My goal is do do standard double-buffering of the DMA output, switching buffers upon completion so DSP can be done while new data is being streamed in....
Hi, I generated a project for STM32F429 in CubeMX 4.27.0 using USB_OTG_FS and USB_OTG_HS (internal) as Mass Storage Host Class. But in the generated project, USB_OTG_HS does not work in (FS) mode. While searching for the error, I noticed that in the ...
Posted on December 02, 2015 at 19:36Hi to All, I would like to share my experience to create test application and measure the USB performance for both FS and HS with external ULPI PHY (USB3300) on STM32F4 MCU series. To do that Olimex STM32-H405 boa...
Hello,I have an application developed on top of a Nucleo Board (F446RE). This application uses the STM32 serial lines connected to the STLink MCU and accessible on a computer through an USB VCP.The F446RE Uart is initially set @ 921kbps and is workin...
Hi,I have STM32F767 - Nucleo kit. I implement FreeRTOS, lwIP. And I create this connect.struct tcp_pcb *server_pcb; struct server_struct { uint8_t state; /* current connection state */ uint8_t retries; struct tcp_pcb *pcb; /* pointer on the ...
The driver has been successfully installed and used on my computer to communicate with the STM32F769NIH eval kit over a microUSB to USB2.0 cable at full speed (the STMicro chip being the device and the computer the host). I then took the STM CDC driv...
Hello,I am searching for this since 2 days but the only things I found are missleading. This (https://www.st.com/content/ccc/resource/training/technical/product_training/98/89/c8/6c/3e/e9/49/79/STM32L4_Peripheral_USB.pdf/files/STM32L4_Peripheral_USB....
im having trouble to send a bytes packet with CDC_Transmit_FS function.For example: CDC_Transmit_FS((uint8_t*)SendArray1,512);Doesnt work for me, it sends garbageBut if i sprintf bytes and send them in a loop, it works perfectly, but it sends data in...
