[fpc-pascal] Realtime and freepascal???

[Darius Blaszyk]

Hi all,

Thanks for all the feedback I got. I am looking into different solutions
and admittedly I'm at a loss. For the data acquisition part I indeed will
not be using an MPU. Instead I found some good references to using arduino
in a master / slave setup. The master will poll all slaves over I2C and
transmit the data using a simplified xmodem protocol over RF.

One last point I have not covered is the use of video. For that I will need
an MPU and as it stands I am thinking about using a Raspberry PI. I found
this link on GPIO handling from FPC https://github.com/inforisorse/fprpiled.
Anyone have a reference on reading HP video from RPI?
