4D Systems Raspberry Pi Library for Visi-Genie
Library for the Raspberry Pi to allow easy communication between 4D Intelligent Display modules running ViSi-Genie programmed from Workshop 4, and the Raspberry Pi.
This library is also required for the Raspberry Pi demo programs.
=======================================================
-
Added the following function:
genieWriteStrHex (int index, long n) genieWriteStrDec (int index, long n) genieWriteStrOct (int index, long n) genieWriteStrBin (int index, long n) genieWriteStrBase (int index, long n, int base) genieWriteStrFloat (int index, float n, int precision)
=======================================================
-
Added the following function: genieWriteMagicBytes (int magic_index, unsigned int *byteArray) genieWriteDoubleBytes (int magic_index, unsigned int *doubleByteArray)
-
Added additional Struct : genieMagicReplyStruct : cmd, index, length, data[100]
=======================================================
make
sudo make install
=================================
sudo make uninstall
=====================================================================
-
Connect your raspberry Pi up to the Internet and download WiringPi library from github:
cd
git clone git://git.drogon.net/wiringPi
cd wiringPi
./build
-
This will then download and install the wiringPi library, assuming you have git installed on your Raspberry Pi already.
-
If you encounter an error such as: error while loading shared libraries: libgeniePi.so: cannot open shared object file: No such file or directory do the following:
sudo ldconfig -v
This should solve the problem
- Please see here for more detail if you need to install git also (https://projects.drogon.net/raspberry-pi/wiringpi/download-and-install/)
=================================================================================
-
From terminal, launch leafpad (or your chosen editor) with root:
sudo leafpad
-
Nagivate to /boot/cmdline.txt and remove the following text (LEAVE everything else intact)
kgdboc=ttyAMA0,115200 console=tty1
-
Save the file, overwriting the existing one.
-
Navigate and edit /etc/inittab
-
Comment out the bottom line by putting a '#' symbol at the start of it, where the bottom line is:
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
-
Save the file, overwriting the existing one
-
Reboot your Raspberry Pi
