Enabling freeRTOS should not require setting system time base when using LL

By default, when using HAL, it is required to set another time base source instead of SysTick as it is used for freeRTOS, but when using LL for all the peripherals, it shouldn't be necessary as LL does not use SysTick interrupt as HAL does.I think th...

USB host doesn't support hubs but some dual function keyboards work - how?

We are still waiting for USB Host Hub support (will it ever arrive?) but in the mean time I'm trying to understand how some keyboards with built in touchpads work but others don't. Obviously, if they have a built-in hub and the keboard always connect...

Is there HAL version macro defined somewhere?

I need to know HAL library version number during device firmware build process. Is there something like __HAL_VERSION_1_9_0__ or similar defined in the HAL library code?Thank youDan

Where can I find a driver for TLV320AIC3204IRHBR audio codec for STM32F779NIH ?

Jumping to bootloader from user code in STM32L476

I am trying to implement a procedure to update firmware in a STM32L476 by jumping to the bootloader from user code. I am able to connect Boot0 to 3,3V and enter the bootloader just fine. But trying to jump there from user code seems to be giving some...

DFU_Standalone project

I am trying to implement the DFU on STM32. So taking the following project as reference.Everything working well.DfuSe_Demo_V3.0.6STM32Cube_FW_F4_V1.25.0\Projects\STM32F429ZI-Nucleo\Applications\USB_Device\DFU_Standalone\SW4STM32But when I reallocate...

NUCLEO-H743ZI2 bootloader Issue

Hi,I have shorted BOOT0 pin to Vdd of Nucl0-H743ZI2 and wanted to issue bootloader commands over I2C bus(PF0 & PF1 are used).I am observing RED led to be turned ON as soon as bootloader is loaded and i am not getting ACK from H743 . But if bootloader...

Using f_write in a loop to write multiple chunks of data, doesn't seem to work

I'm using the following code: //100KB buffer uint8_t testBuffer[100000];   for(int i = 0; i < 100000; i++) { //Fill buffer testBuffer[i] = 'U'; }   BSP_LED_On(LED_BLUE);   for(int z = 0; z < 5; z...

I've downloaded a patch to STM32Cube_FW_L0_V1.11.0. Now that it's downloaded, what should I do with it?

Firstly, I downloaded STM32Cube_FW_L0_V1.11.0 and, following the instructions in the documentation that came with it, extracted it to a folder. I presume that this is all I need to do to enable using within STM32CubeIDE - simply navigate from the ID...
