Re: Turn Raspberry Pi into a P.L.C (Programable Logic Contro

Hello, The etherCat module of "etherlabs" works fine on the raspberry pi ! Even without RTAI Kernel ! Of course if you want short bus time, by ex. for motion control, you should port RTAI Kernel on the raspberry pi... I test it with beckhoff EK1100 EthercatBus coupler and with EL1819 2 x 8 digital ...

Re: Porting Android

Ok...but i made 2 hypothesis 1) LibEgl is only to run java apps using OpenGL ES and Android HMI is separate => That not explain me why famebuffer is shared by console and Android HMI... 2) LibEGL and Android HMI are linked together by SurfaceFlinger.

Re: Project: Android JB 4.1 with Hardware acceleration

To enable the double buffering into bcm2708_fb.c

But don't know how vc support double buffering.
And we must modifiy/add page flipping function (panning)

I compiled and booted sucessfully JB on rpi.
