I assume the PULSOUT statements are for servo motor control (you didn't say). If so, these pulses have to be produced about every 20ms or the servo motors will shut down and their movement will become jerky. At 9600 Baud, a SEROUT statement can send about 20 characters in 20ms which will leave no time for the PULSOUT or anything else in 20ms. You could possibly handle 5-10 characters total between PULSOUT statements. Your best solution would be to use something like a Parallax Servo Controller (PSC) or a ServoPAL. These take over the PULSOUT function and issue the pulse every 20ms. In the case of the PSC, you control it using a SEROUT statement. The ServoPAL you send the first pulse and it just repeats it until you change it. Read the documentation for these for details.

·i do have the servo controller board that you mentioned.
· i think what confused me was the fact that i copied and pasted the·3 source code· programs, (the· servo,lcd and the speech board),all into the editor.
· can i do that so it's easier for me or no?
THANKS!!!·

No, you cannot do that. A program is written to perform a specific task. Adding more programs in doesn’t mean they will ever get created. On top of this you may have conflicting I/O pin assignments, constants and variable declarations.
