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.

[oopic] Re: Strange serial operations

Even with only this,

Do
If Serial.Received Then
buffer=Serial
buffer.Location = buffer.Location+1
End If
Loop

it still loses anything after 13 characters (total of 16 being sent).
It doesn't look like my load cell display can actually use any
hardware control. Its pin 7 & 8 are jumpered internally. Is there any
possible work around?
