Probably elementary stuff, but am brand new to ARM and STM32. I'm using a USB stack libusb_stm32 for learning. In this stack, when data arrives from the host PC, a callback in the USB ISR runs a function of mine to put the data into my queue. In this...
I'm connecting to a nucleo144 through configured pins and i2c connection a melexis 90640 (thermal scanner) I initially tried through Hal functions to call the device on the default address I had from the datasheet (0x33) but did not find it so I solv...
Hello,I've made several bootloader in the past without so much problem in the past with F2, F4, F7, but this time, I have some serious troubles with a STM32H743BI :)The bootloader (using the first sector, 128kb) reads a bin file from the SD card and ...
I am using STM32F722ZE MCU. I am successfully implemented micro SD FATFS USB Full Speed MSC.The problem is every time I plug the board to PC, it took so long, up to 40 seconds, for the USB enumeration to be completed.Can anyone help me to point out ...

Hello! I am trying to get the USART1 (only using as a UART) for the STM32F411CE. I have been doing some studying on the STM32407VG and got the UART to work with straight register manipulation. (That was done here: https://community.st.com/s/question/...
Hello, I am working on a project. One of the requirement is to be able to upload firmware and communicate with the microcontroller is via SPI interface. The layout of the project is as follows:1) There are 10 microcontrollers in total. Each running s...
Hello, I'm quite a newbie and I'm sorry if I don't understand something simple :\STM32CubeIDE 1.7.0, STM32CubeMX 6.3.0I would like to make a simple synthesizer on STM32F769I-DISCO. Right now I managed to modify the example repository "STM32Cube_FW_F7...
Hello together,I have a question regarding caching on AzureRTOS ThreadX/NetXDuo. At the moment I am switching from freeRTOS + lwIP to AzureRTOS ThreadX + NetXDuo. So far everything works but I have some questions regarding caching. I know that the et...
