Filling%20the%20Pause

1
Filling the Pause

• Sound and Motion
• with the Boe-bot

2
Silent running

• for x 1 to limit
• pulsout left_servo, 850
• pulsout right_servo,650
• pause 20
• next

3
Melodic running

• for x 1 to limit
• pulsout left_servo, 850
• pulsout right_servo,650
• freqout speaker, 20, myfreq
• next

4
Getting a beep -- I

• Design a cycle
• LED 1 on for 600 msec (27 loops)
• LED 2 is off
• LED 2 on for 600 msec (27 loops)
• LED 1 is off

5
Getting a beep -- II

• Add a counter
• myc 0
• for x 1 to limit
• other stuff
• myc myc 1
• if myc lt 54 then eloop
• myc 0
• eloop
• next

6
Getting a beep -- III

• Make the transitions
• if myc lt 27 then myc_ge27
• low LED1
• high LED2
• goto myc_end
• myc_ge27
• high LED1
• low LED2
• myc_end

7
A more elaborate example

• While backing up
• Beep
• Blink
• Some code

8
Too many variables

• Define place holders for local variables
• Local variables for subroutines
• t1 var word
• t2 var word
• Rename these in subroutines
• Local variables for goforward
• tgx var t1.highbyte
• tgfreq var t2

9
A little bit about tone

• Tempered vs. Natural tone
• A code fragment
