Right here, we will use ‘Tenacity of Vision‘. Now you must have got across this expression already just before. Yes, this is usually the same technique which can be used in cinematography (display pictures so quick that our human brain cannot differentiate any lag bétween two consecutive images). Likewise, when we mux even more than oné SSD, we dispIay only one SSD at a time, and we switch between them therefore quick that our mind cannot distinguish between them.
Lets state each display will be energetic for only 5 milliseconds at a period, i.elizabeth. it gets lit up 1/0.0045 moments a secs, that's approximately similar to 222 instances/second. Our eye cannot feeling a modification so quick, and thus what we see is usually that all the displays are functioning simultaneously. What will be actually occurring in the equipment is usually that the MCU provides ‘1' to the pin (remember, giving ‘1' to the base of a BJT shorts the Extractor and emitter junction?), which will be connected to the base of the transistór of the respective displays, helps to keep the port ‘ON' for 5 milliseconds, and after that transforms it off once again. This method is place in an countless loop, so that we find the display regularly.

Configuration bits For PIC18F4550. Configuration bits are special bits used for controlling different features in the Microcontroller. These are read during startup/reset and enable or disable different hardware features based on the values of bits.
