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...
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....
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...
Hey guys,I used ST CubeMX(v5.2.0) with TrueSTUDIO IDE in Windows 10 PC. My work is to generate a new project for STM32 F411E DISCO board and tweak and implement the examples given for STM32 F446RE board in the ST's FP-AUD-SMARTMIC1 software's projec...
Hi,I'm trying to dynamically change sysclk frequency in STM32L011xx. It's quite easy for STM32L4. All steps are described in detail in RM for L4 (here is what I extracted from RM: https://pastebin.com/KcCZNGAr) - my implementation here: https://githu...
I'm using the STM32H750. Using the discovery kit I developed a system that always boots into the system bootloader. When I start the application code using a dfu-util, the application code starts a USB FS CDC device and I can communicate with it as v...
what i noticed is if i create n no of files, only 8 files are displayed however the remaining files are also created but not displayed, i am using elm chans fatfs. What could be the problem why only first 8 files displayed on pc .Kindly let me know ...
