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...
Hi everyone,I have published a small bare-metal USB-C Power Delivery sink example for STM32 MCUs with the built-in UCPD peripheral:https://github.com/robobtnet/stm32-usb-pd-baremetal-sinkThe goal is to keep it minimal and portable:- no FreeRTOS- no S...
I am working on SDRAM execution using FMC on STM32H563ZI (NUCLEO-H563ZI board) with external SDRAM connected through FMC interface. Our target is: Execute application sections from SDRAMPlace heap and stack in SDRAMEnable automatic scatter-loading/...
Hello everyone! I have a problem with reterning ticks in line "measure_speed_rpm = speed_reference / LL_TIM_GetCounter(TIM2);". speed_reference is const variable and equals 15000000. When I looked at Serial Monitor, it's indicated: (picture)That's me...
Hi Community, I'm a new Developer/ for ST Microcontrollers, Now Im currently using STM32H723ZGT6 (NUCLEO - 144). Im currently working on ethernet (LWIP), the ping is not working for this code that i have generated . I have seen some youtube channels...
Hello STM32 Community,I am developing a system on the NUCLEO-N657X0-Q using ThreadX and NetX Duo and I am having a hard time to make the ethernet work. I want to implement a web server in my system but I cannot make the Ethernet communicate.Problem:I...
Split from this thread My firmware is based on this ccid usbd driver https://github.com/STMicroelectronics/stm32-mw-usb-device/blob/master/Class/CCID/Src/usbd_ccid.c . The issue that I face, the PC finishes receiving data immediately after receiving...
