Hi.I was working on my small pet-project, trying to develop USB mic on my stm32f4 discovery board. I was successfully completed this project but still not fully understand how it`s working. Function DCD_EP_Flush really confuse me.My device work as fo...
Im using STM32SD library on my stm32f407vet6 board. I want to make a logging system for my application. My initial logic is: on setup we count number of files in our root directory and create a new file named dataLog{fileNumber}. Then we write data ...
Hello everyone,I'm working on a project using the STM32F334R8 MCU to capture two rising edge signals with the intent of obtaining the CNT value at each signal's rising edge. My calculations and data are meant to be processed through an external inte...
Hi folks,I've got an F429ZI board which works fine, I've run a few samples and I've had zephyr applications running on it no problem. What I now want to do is set up my own small project using the bare minimum of third-party code to begin. I used Cub...
Hello everyone,My company bought a card ... We want to use the 4 bit SD card.I generated a System Workbench for STM32 project (FatFs) , without modifying anything in the GPIO, SDMMC or other properties.Compilation and programming is done without prob...
I was struggling to get LwIP TFTP server working on MCU boards (NUCELO-H743ZI). After debugging I have found:Why is TFTP_MAX_MODE_LEN defined as 7 (instead of >= 8)?Why is TFTP_MAX_FILENAME_LEN just defined as 20?So, it results in:sending (PUT) or re...
using stm32h753bitx controller and their latest HAL drivers. On the every reset RTC loses one second. It also loses time while the device in idle condition.My devices uses main battery power and coin cell battery for backup.Here's my RTC initializati...
I am trying to get the PCM1808 ADC working on my STM32H7 using Cube IDE, but get stuck regarding endianness.I understood STM32 is little endian and i2s is big endian. I am trying to receive 24 bit data via DMA but when reading my DMA buffer I am not ...
I using the stm32L4+MT29F2G01 and the latest Filex library from ST 2.0.0 (6.2.0 AzureRTOS). After the format, the performance is satisfactory for me (250ms write 2048B), but after saving a few files of about 1MB each, the efficiency drops sharply, th...
I am using the NUCLEO-G474RE along with the X-NUCLEO-SRC1M1 board to create a USB-C power delivery source. I am also using the "SRC1M1_Source" example project in the x-cube-tcpp software download.I am attempting to provide a 20V, 5000mA source to a U...
