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

* This IO driver replaces the FB based program calls with mappable hardware channels,
* 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 Microsystems uploaded a video about the Mega IO Industrial for Raspberry Pi, check it out :

## i2c address setting

### install i2c tools

sudo apt-get update
sudo apt-get install i2c-tools

### MEGAIO i2c address

Be sure the MEGAIO is 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).
