control algorithm for LED shift register
Friends, which algorithm do you use to control the LEDs in this structure? I need your ideas. I have prepared a table of the LEDs' turn on order.
Nx_TCP_Echo_Server with static IP
Hello,I need the TCP Server with static IP address. I chose the Nx_TCP_Echo_Echo_Server example and NUCLEO-H723ZG board as a starting point. I use the STM32CubeIDE 1.19 with latest x-cube-azrtos-h7-v3-4-0 sample files. So I imported the Nx_TCP_Echo_E...
STM32 CDC ECM HOST Lib
Hello,I'm working on an adapter USB to Ethernet and it is working only as a DEVICE. Now I would like to do the same but I want my STM to work as HOST.Is ST providing the same code stm32-mw-usb-device but for host?Thanks,G.
