Fc9-type-7-icon.png Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.

Fc9-type-7-icon.png Simulate Comms
Allows the simulation data to come from the panel GUI or relayed via an injector component.
