Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
CubeMX USB MSC creates a large protocol stack to allow USB MSC to get to MMC memory device. This all runs directly from the ISR. We want as much of this to run in a user thread instead.My concerns are how will the low-level USB work with this kind of...
Hello Community,I can create projects with CubeMX and CubeIDE to transmit or transmit/receive USB Virtual Com data with a STM32F401CE.As soon as the I2C peripheral is enabled, the USB fails. Commenting out the added lines indicates that this is the ...
Hello We need to interface TDM bus with USB from i7 based embedded PC. I saw "STM32 USB Device Audio Streaming software expansion for STM32Cube" and I am consider using it. Let me put here our requirement, possibly someone can comment if what we need...
Hi All,I have ported mpu functionality by replacing port.c and portmacro.h.In code, we are creating task which toggling led after every one second.but this above code run only in debug mode only.while i am running code in run mode, task is not cr...
So far I have been using VCP in my project for about six months with no problems. But today I found it was not able to send a specific 'packet' of bytes.Here is the SWV printf output from STM32CubeIDE:Sending 10 bytes 255 254 5 0 19 0 0 0 24 106Note ...
Hi,I have created a CubeMx project for STM32F042K6. I am using following components:USBTSCIWDGGPIOTOUCHSENSINGUSB_DEVICEI just defined the pins and tried to compile but compiler says FLASH overflows around 2.5KI didn't even write one line of code. Th...
I want to customize System memory UART Boot-loader and will use as Flash Memory Boot-loader. Please share the System memory Boot-loader Source code or the link where it is available.RegardsVijendra
I'm planning to use the built-in ROM bootloader in an STM32F4 chip for DFU uploads and having a hard time figuring out how it works exactly (in particular what pins it initializes at what moment in the boot process, and what I need to do externally t...
I have an issue with STM32L462 when using the ROM bootloader via UART to enable readout protection. It just hangs after enabling RDP level 1 and requires power cycling to recover. With several other STM32 MCUs (F0, F3, H7, ...) this seems to work.The...
To save the least uA in one design I leave the VDDUSB unconnected until a powered USB is plugged in. When the 5V from USB is present a transistor enables the 3.3V to reach the VDDUSB pin.The code generated by CubeMX strightly calls MX_USB_DEVICE_Init...
