Hi I want to use Promiscuous Mode with LWIP+STM32H743.I want to be able to capture frames not sent over to my IP address.Is it possible?Thanks
What is the difference between HAL_FLASH_Lock and HAL_FLASH_OB_LockAndrzej
we have several device with STM32H753, and they are talking to each other, over LwIP.one of the devices is the master who charges on the protocol communication between all other peripheral devices.the master send a ack message to each device in a loo...

Hello everybody!Is anybody tried to connect an STM32 to an KSZ846x (for ex. KSZ8463 - 3 ports ethernet chip MAC+PHY) chip? I have a very strange issue. I am able to communicate with the KSZ chip using MIIM and also over SPI, and I am able to start th...
Hi I made a custom board with "stm32f746". This board has a 32MB sdram (MT48LC16M16) and a "800×480" lcd. I use from STM32CubeIDE and touchgfx. I want to allocate 2MB of sdram (from 0xC0000000 to 0xC0232800) to frame buffer of lcd and I need to use r...
