Resolved! Will CubeMX support freeRTOS for the STM32U5? It currently only has ThreadX. Will ThreadX support be expanded?
We are currently using Keil uVision.

Resolved! STM32H7 64MHz HSI is off by 4%!
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...
Resolved! Maximum sampling on USB audio class 1.0
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 ...
Resolved! When CANBUS interrupt is activated, then USB connection does not work - Help with priorities
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...
Resolved! Unable to wake task from event flag in ISR when USB_FS is enabled using CMSIS OS 2 on STM32L5
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...
HID IN data transmission frequency is only about 10 times per second
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...
STM32F105 DFU BootLoader does not work
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...
Resolved! Having issues getting POST (upload file from web browser) to work in an STM32F407 project
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...
How to transmit and receive float type variable with TCP LwIP?
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.
