For now I have this topics<br><br></div>- Write driver using kernel NAPI (I already have a driver working with cdev API)<br></div>- Write new protocol and export to userspace as a new socket type (no ideia on this)<br><br></div>As example I'm using the linux socketCan, I want to do like they did, but with nRF24L01+. I have no ideia how this two topics touch one each other... Any documentation, simple examples, tutorials, guide lines, articles or irc chat on subject is welcome, I look on LDD3, but its outdated, I'm using kernel 3.0 for development, <br><br></div><div>As first version requeriment I want to send frames (32 bytes fixed) with sendto() and receive (32 bytes fixed too) with recvfrom()... Messages should be enqueued while sending, the driver need to iterate over a circular list of remote nodes, exchaning frames and delivering the received to userspace... <br><br></div><div>Something like:<br></div><br></div><div>for (;;) {<br></div><div> node *n = get_next_node();<br></div><div> send_frames_to(n); // <- send enqueed frames, unblocking sendto() caller<br></div><div> receive_frames_from(n); // <- deliver received frames to recvfrom() caller<br>}<br></div><div><br>Thanks in advance!<br></div>Cheers<br clear="all"><div><div><div><div><div><div><div><div><div><div><div><br>-- <br><div class="gmail_signature"><div style="text-align:right"><i>"Do or do not.
