<div dir="ltr">Hi all,<div><br></div><div>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.</div><div><br></div><div>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 <a href="https://github.com/inforisorse/fprpiled">https://github.com/inforisorse/fprpiled</a>. Anyone have a reference on reading HP video from RPI? </div><div><br></div><div>Rgds Darius</div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Jun 7, 2018 at 2:01 AM Brian <<a href="mailto:vmst@golden.net">vmst@golden.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">The brief description of your project suggests that it may not need "hard<br>
real-time" , since you are planning to write to flash memory or send the<br>
data over an RF link. Hard real-time usually implies receiving input data<br>
and responding with an output control in a timely and predictable manner. <br>
<br>
Your application seems more like data logging where you don't want to lose<br>
any data , and in that case Linux will suffice if you use a 1Gbps Ethernet<br>
link which I have tested using Synapse and handles data at roughly 800Mbps<br>
using Free Pascal.<br>
<br>
If you have access to hardware such as FPGA , or some special hardware ,<br>
then preconditioning the data using buffers removes the need for hard<br>
real-time and Free Pascal running under vanilla Linux will more than<br>
suffice.<br>
