X-CUBE-CLASSB on STM32F072, STL_StartUpCPUTest causes hard fauilt
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...

Software configuration of SPI NSS to run multi-slave one master SPI system for STM32L412 chip
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 ...
Finding issues in initializing the USB as CDC in the STM324x9I-EVAL board.
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...
During nand flash erase, uart interrupt doesn't work properly.
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...
Bug in HAL libraries when using multiple DMA request to different channels of same timer
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...
Chip selection for 2-port CDC host
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.
STM32L412 VDDUSB Disconnect
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....
How to compare bytes received in a uint8_t?
I have a STM32F103C8T card, I am developing an application that receives a byte array by usb / serial.I have a variable "uint8_t USBBuffer;" in "usbd_cdc_if.c" which stores the bytes.My question is: how can a non-vector variable receive an external m...
