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...
I am now ready to write to flash when receiving a file upload via my webserver. However, I read that when erasing or writing to flash, flash reads are blocked. I can see this causing problems. The LwIP_IAP example which was written for the F407 mu...
I have built an HTTP webserver on my STM32F407 custom board. I have multiple pages working. One of the pages lets the user select a file using the browser and upload it to the webserver. All of that is working. My issue is that when the upload co...
We are currently using Keil uVision.
According to the STM32H745xI/G datasheet, the 64MHz HSI is accurate to +/- 0.3 MHz around room temperature, so +/- 0.5%.During testing, I noticed about 10-20% of my UART characters were getting dropped. I then looked at the signal on a scope and noti...
Hello,Is it possible to use USB full speed (12 Mbit/s) combined with audio class 1.0 to transfer 16bit audio data sampled at 384ksps ? According to my calculation, I need to transfer 768 bytes/ms over USB:384000 * 16 = 6144000 bits/s ...
Hi!I don't know really how to explain this. But I have enabled CANBUS and it works very good. I also have activated USB and it works too.But since I have changed the preemption from 0 to 1 for CANBUS RX0, I have no ability to use USB connection.I cha...
I have been using USB_FS for some time now and recently added the EXT13 IRQ for the user button in the STM32L5 DK. I set a task to toggle a pin when the button is pressed and noticed that if the USB is running, the event does not wake the user button...
I used ThreadX and USBX in the project. When I only use USB as a HID Device, STM32 can transmit data to the PC 1000 times per second, but when I use USB as a CDC+HID composite device, the transmission frequency of HID is greatly reduced. Will increas...
I successfully used USB DFU on STM32H7, and I want to perform the same operation on STM32F105. I learned from the manual that the system BootLoader address is 0x1FFFB000. But when I try to jump into USB DFU mode, windows prompts the device descriptor...
