|Subject:||[lwip-users] Memory use for connection with callback function|
|Date:||Tue, 30 Apr 2013 13:56:01 +0200|
i've written a very effective IP handling task to safe memory and processing time in a system with a small memory footprint. For a most effective speed and handling I'm using netconn's with callback functions to just process what's coming in instead of polling each connection with a wait time of 1ms.
Unfortunately I've seen that each existing connection lowers the available RTOS memory by around 300 bytes as it seems to create a message queue in the system. Not being sure why such an amount needs to be used just for the callback, is there any way to get rid of this use – or even lower it? This is actually up to 3 kBytes for 10 simultaneous connections – memory which I don't have left …
