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. It is written for educational purpose only.

• 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 :

Changelog

• v2.0.0.0 info

Initial release on cForge. See https://forge.codesys.com/drv/io-drivers/database/Home/ for details.

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 benefits

• Simple I2C Address Parameter access;
  

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

• Example Project with visualisation
