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...
We have a custom board with an STM32F407 on it. I used CubeMX to create the project and enabled HTTPD. I used the example LwIP_HTTP_Server_Netconn to get a webserver running. I have a few pages working including a dynamic page. Next step was to c...
Hi,I am trying to send and receive the float variable between STM32H745 and my PC. I can only transmit and receive strings. Is it even possible to handle any type of data rather than string. Thank you.
