Incomplete isochronous IN transfer

I am working on enabling feedback for the PLAYBACK endpoint using STM32H750XB. I was successfully able to control the packet transfer between host and device based on feedback data sent to host, it plays for hours, no issues at all, no rollovers, no ...

Does anyone use LL library to generate PWM ? I am trying to generate 4Mhz PWM on the STM32F401RE. Any help will be appreciated ? A sample code will be very helpful.

Need to get an inaccessible STML041 into the embedded bootloader via UART, driven from an STM32L051xx. Need a documentation that describes: 1) getting from my app into bootloader mode via UART, 2) use BL to re-flash the L041 with data from L051.

I'm a newbie to STM products. Lots of experience with other vendors, and am used to seeing example solutions that go from point A to point B. STM seems to provide tool descriptions (and I understand why given the combinations of tools, versions, pr...

I have an STM32H735G-DK and I am trying to figure out which of the example projects show how to use the ADC_IN connector (CN1)?

STM32F446 crashing when calling xSemaphoreGiveFromISR from within USB ISR (CDC_Receive_FS)

I have a stm32f446 setup with a virtual com port. I using a task with FREE RTOS. The task is blocked by waiting on a semaphore (xSemsphoreTake). In my CDC_Receive_FS routine I am simply calling xSemaphoreGiveFromISR when ever this function is called....

OTG USB differences between CPUs

Looking at stm32 USB library for USB device (not host)( particularly for 32F769) I noticed in source code, different approaches between core ID 300A and core ID 310A. However I found no documentation that explains that versions. Does someone know wha...

How to Test for Brownout?

I have a USB HID product based on the STM32F205. We've built thousands of them. However, recent builds have shown about a 5% failure rate where the device fails to enumerate (some of this 5% might fail 50% of the time when power cycling, some 90%+). ...
