This Forum is Dedicated For all The Object Oriented PIC Lovers .......... The concept behind OOPic is straight forward. Use preprogrammed multitasking Objects from a library of highly optimized Objects to do all the work of interacting with the hardware. Then write small scripts in Basic, C, or Java syntax styles to control the Objects. During operation, the Objects run continuously and simultaneously in the background while the scripts run in the foreground telling the objects what to do.

Re: [oopic] Re: Using ultra sonic sensor with the oopic

There are 7 A2D lines on the ooPIC - The ooPIC R and ooPIC C use the
upper 3 for LEDs and buttons but the ooPIC S has all of them available.
The ooPIC does not read PW well and serial I/O is not its strong suit.
I've used the MAXSONAR units on other micros and there too I used the
A2D as the simplest way to get the data from multiple units.
