Hii, This is the first time I'm working with a dual core H7. My Board is Discovery kit with STM32H745XI. l reserch very much but there is nothing about Ethernet on STM32H745. No example no asking questions. l cant find.l need to Tcp Connection on Eth...
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...
