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....
