# CODESYS V3 MEGA-IO driver v2.0.0.0
This driver is a IoDrvFB based wrapper around the CODESYS Raspberry I2C MEGAIO driver v1.1.0.0 by [Sequent Microsystems](https://www.sequentmicrosystems.com/index.html).

* To optimise I/O dataflow, some small codechanges to the I2C MEGAIO driver v1.1.0.0 were neccessary, 
* 100% Open source,
* 100% Pure IEC 61131-3 code (ST)

Sequent uploaded a video about the Mega IO Industrial for Raspberry Pi, check it out :

# I2C address setting
Start your Raspberry Pi with te MEGAIO attached.

* Run sudo i2cdetect -y 0 => You should now see a table with the connected i2c slave address.
* If Run sudo i2cdetect -y 0 does not work, Run sudo i2cdetect -y 1

The MEGAIO default address is 16#31 (41dec).

# IO interface
The IO interface of this driver has been reworked to accomodate a simple but more powerful approach:

* Simple I2C Address Parameter access;

* Hardware I/O Mapping instead of function block calls in your program
