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...
Hello everyone, when I was watching the stm32f429 routine, there was an example of upgrading the user program with the U disk. It was mentioned that the configuration of the user program needs to change the contents of the [toolchain linker file]. Wh...
We have some products in the field that have historically used DFUseDemo together with the Windows driver "STTub30.sys". That worked well as it is quite a concise tool that is easy to install.ST have replaced that with STM32CubeProgrammer which is m...
I made a High Speed USB DEVICE using USB PHY with STM32F207.When delivering data to the HOST, there are small-sized data (less than 512bytes) and large-sized data (more than 1Mbytes).At this time, I want to transfer small-sized data without using D...
I made a High Speed USB DEVICE using USB PHY with STM32F207.A data transmission test to the host is in progress, and transmission is possible up to the size of 0x7FFFF, but it cannot transmit more than that.When referring to stm32f2xx_ll_usb.c, the m...
We have a strange issue with the HID class, the USB Descriptors are returning different results on different laptops. Lenovo Think Pad is fine, Dell 5560 is bad. Has anyone seen this issue before? Maybe a MS bug fix or a Dell driver update? Thank...
I have been having much difficulty trying to port a custom USB HID protocol from a previous project using the STM32F405 to the STM32G431. Connection would initially be established, immediately followed by pipe errors. Eventually I found that if I dow...
While this question has been asked, I dont really see anyone directly answering the question. My design uses the USB3317 and STM32H743, and the USB3317 initializes but seems like some type weird issue. In the USB_DevConnect routine, once the SBx_DEVI...
Hi. I am using STM32L412KBTx for my application. I am using LPTIM for 150ms and 5s timings.The pattern is like 150ms-->5s-->150ms whenever data is received over LPUART.So, for first 150ms timeout value, it runs fine and when I start for 5s timeout va...
