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...
MCU: stm32f427Firmware Version: F4_v1.25.2CubeMX Version: 6.0.1The generated code for USB Virtual Com Class dynamically allocates memory (calls malloc) in USBD_CDC_Init. However, this init function is called under a IRQ context, and I don't think doi...
Hi guys,On USB Host Mass storage mode, I am creating a text file using (f_open(&myFile, "TEST2.TXT", FA_WRITE | FA_CREATE_ALWAYS function.For writing text into the file, I use sprintf(rwtext, "Hello World"); function to write the...
Hi.If you continue to receive packets while executing Uart for the first time, the operation stops.If there is some delay, it's okay, but if there isn't, it suddenly stops.However, if you update the STM32 directly, it will work again.It works even i...
Hello Sir,I am using the STM32H743ZI2 for the interfacing with ethernet. I am totally new to ethernet protocol. I have gone through the example lwIP_HTTP_Server_netconn and also setup all the things as per the readme.txt file .but result is not gett...
So I'm looking at the reference manual of STM32F723 to find out how to control the USBPHYC peripheral. Actually there is no programmer's guide in there like for most peripherals, so I can only rely on the register map to find anything out about it. T...
Hi,I'm having trouble understanding the function of NetX that reads data received from ethernet:static VOID _nx_driver_hardware_packet_received(VOID){NX_PACKET *packet_ptr; NX_PACKET *received_packet_ptr;INT i; uint32_t framelength = 0; ...
Hello everyone,What i am trying:I am trying to send a http Request (with a TCP connection and LwIp) with my STM32F746NG controller to my Respberry PI. The Webserver on that Raspberry Pi has a RestApi. So I can send a command with the http request. I ...
I have seen this with the SPI bus 6 months ago. It just just happened with the IIC bus. I am using Cube 1.12.0 and this maybe related to TKube.1 issue "Potential bug in I2C HAL layer (STM32Cube_FW_F4_V1.25.0) in I2C_MemoryTransmit_TXE_BTF() ?".I ha...
It is well known that STM32Cube IDE & MX both has quiet good support for FreeRTOS, but my question is a bit different and related to SafeRTOS, I'm just wondering if ST has support for SafeRTOS as well or not?!I'm well aware that SafeRTOS comes with l...
