Hello Coders!:

I am searching for a 1 page of pascal code on a Raspberry wiht WIFI
stick to receive strings from the TCP/IP socket and sent them through
a I2C bus and the other way arround, Receive from i2C bus and sent
them through a TCP/IP socket.

To create a ah-hoc TCPI/IP connection between a old laptop and a
Raspberry. Where multiple MCU´s can be connected to the 26 pin GPIO
port on the RPI to i2c.

THe MCU´s Code is written in www.mikroe.com pascal. And the Laptop
code is done in borland delphi.

Also for that a game pad is connected to the Laptop with system
components from www.torry.net.

Greets,

Later to post a question howto view a FFMPEG from a Raspberry in a
delphi/WIN32 window.

I suggest that you start with Synapse based on this post. There are
other possibilities like LNet.

You will examples of how to send/receive TCP/IP.

To send/Receive I2C you probably need to access a C library that can
do this - you should find examples of those as well as how to access a
C library from Lazarus.

Good luck!
