I am working on Ethernet in STM32H745 MCU and using STM32CubeIDE. I want to connect 100 such MCU to LAN. How can I assign a different MAC address to all the MCU? Do STM MCUs have a built-in MAC that I can use, or is there any other method to assign d...
Dear:I use stm32f407+ lwip as tcp server, then the client request freq with 30Hz ,the server will not reply after a time , then the client will retransmittion after 200 ms(see 1.png,3.png),but the data is added to Ethernet DMA, TxBuff(see 2.png), ...
Hi,I'm using STM32 family for a very long time for lot of clients. My clients want to use linux system just for the screen and the wifi capabilities and I want to use STM32H7B3I-DK as reference and design cheaper and more stable system (I dont like t...
hello dear forum,I want receive varying no of char from UART in IT modeHAL_UARTEx_ReceiveToIdle_IT() function is good but how to know amount of received chars ?thank you
Hello Community,I'm working on stm32u5(B-U585I-IOT02A). B-U585I-IOT02A has two digital mics, and St officially has an example of BSP to record audio.So after taking references from: https://github.com/STMicroelectronics/STM32CubeU5/blob/main/Projects...
in main.c int connectionClosed = 0; ... Setup routine of socket ... while(1){ sin_size = sizeof(struct sockaddr_in); new_socket = lwip_accept(s_create, (struct sockaddr *)&client_addr, &sin_size); if (new_socket > 0){ msgSize = sprin...
I want to implement a complementary PWM pattern using the deadtime feature of the STM32G474. I found this example:Interestingly, the deadtime is not implemented with the on-chip deadtime feature, but with using multiple compares. Why is this?Is the s...
I am writing SW in python to eventually program the STM32G051K8 over the UART from a BeagleBone Black (BBB). For testing I am doing it from the PC with a TTL-232R-3V3-WE USB to TTL Serial adapter. At the moment I am making routines for each command...
I will mention at this point that I am connecting to a known working CDC device. I know it is working because I can connect the same port to a PC, and it enumerates properly, and I can pass data to/from the device.In module usbh_core.c function USBH_...
I should add, does the DMA process itself carry on in the background. I realize that the statement is blocking.
