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-conn-icon.png Simulation
Fc9-type-7-icon.png Simulate Comms
Yes: Accelerometer data will come from the simulation component sliders. No: Accelerometer data will come from the CAL component - I2C or SPI - API etc
