Using E$-$Blocks $-$ Flowcode v$5$ Using E$-$Blocks $-$ Flowcode v$5$

Create a flowcode program which turns on all pins on PORTB sequentially for

$0\mathrm{.}2$ second.

Example:$-$ Turn on RB$0$ only for $0\mathrm{.}2$ seconds, then RB$1,$ then RB$2$ and so on$.$

When RB$7$ has turned on$,$ then the cycle must repeat back at RB$0,$ RB$1$ etc.

Hint:$-$ Create a variable say count which is used to drive PortB where you initialize

the variable count to $1$ and then multiply it by $2$ on each iteration of the loop. You will

also need to take into account when the count variable overflows, so it starts back at

B$0$ after B$7$ illumina

Modify the previous exercise $1)$ so that when RB$7$ turns on the next light to turn on

is no longer RB$0,$ but RB$6,$ then RB$5,$ RB$4$ etc. The idea here is to create a Night

Rider Effect on the lights.

Hint:$-$ Use a variable which is called say count$\_$dir which detects that you are

counting up $($count $=$ count $*2).$ When the count value reaches $128$ you change the

variable count$\_$dir to $0$ and then count down $($count $=$ count $/2).$
