Usage

After installing and restarting the node-red you will see on the node palette, under the Sequent Microsystems category the "16inpind" node. This node will output the state of one of 16 inputs if the channel parameter is between 1 and 16 including. The node will output a bitmap of all 16 inputs if the channel parameter is 0. The card stack level and channel number can be set in the dialog screen or dynamically thru msg.stack and msg.channel.

Important note

This node is using the I2C-bus package from @fivdi, you can visit his work on GitHub here. The inspiration for this node came from @nielsnl68 work with node-red-contrib-i2c.Thank you both for a great job.
