Hi, I would like to develop an Ethernet device with an ARM uC. I am using a raw lwIP on it. Latter I would like to use more devices which are connected to a switch. A PC which is also connected to the switch will send a broadcast message which starts these devices. My problem is that the devices should start the working at the same time. The starting time difference between the devices should be under 10 uSec. Is it possible without PTP? Can you give me a development direction? My current example program work with a timer. The timer periodically 10ms trigger an Ethernet interrupt, but this 10 ms cause my starting problem. Can i use a simple Ethernet interrupt instead of timer?
