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...
Hi,I have some difficulties to configure USB device using OUT EP double buffering (used with CC class).While using simple buffering we get slow transfer rates (1 out o 2 packet NAKed), when I use HAL_PCDEx_PMAConfig(PCD_DBL_BUF), USB transfers hangs....
Hello community,is there example codes reflecting the application note (AN4112) for the capacitance measurement?Thank you.
Hi, we've got the class B self test library running on our F072RB, with one exception. If we include the call to STL_StartUpCPUTest() inside STL_StartUp(), then a following call specifically __CRC_CLK_ENABLE(), will cause a hard fault. We did some d...

I am hoping to understand more the process behind this. From what I understand, the NSS can be in either a hardware or software configuration. Reading the reference manual [Section 40.4.5], it appears that if the NSS is placed in software management ...
I am trying to establish communication between windows 10 and SMT324x9I-EVAL board through USB by setting USB in CDC class.For starting with, i have used example application given with stm32f4 peripheral library package(en.stm32cubef4\STM32Cube_FW_F4...
Dear allDuring nand flash erase, uart interrupt doesn't work properly. (same SysTick_Handler)Let me know why this is happening.nand flash erase source :for(Addr.Plane=0;Addr.Plane<2;Addr.Plane++){ for(Addr.Block=0;Addr.Block<2048;Addr.Block++) { HAL...
I am having a problem getting two DMA requests started for the same timer. One capture is an IC (input capture) and the other an OC (output compare). See the following code snippetHAL_StatusTypeDef status; status = HAL_TIM_OC_Start_DMA(&htim3,TIM_CHA...
I need a 2-port host that can bridge 2 CDC slaves. What is the best chip for doing this? I don't want to spend much time doing software development like writing CDC drivers.
I am using STM32L412RB for a low power application.VDD: 1.8VI have a 3.3V regulator that I would like to only turn on when I am using USB. According to the datasheet (https://www.st.com/resource/en/datasheet/stm32l412kb.pdf pg 19), VDDUSB = 3.0 to 3....
