Conflict when I use interrupt and RS232 component.

[WalkOver]

Hello !

I have to drive two servo motor and receive 14 octet at 19200 bauds with the RS232 component. As soon as I receive data, the servo motor position change without any reason.

To drive my servo motor, I don't use your examples program. I use only one interruption (TIMER0) and I set RA0 for exemple. Then I put a delay ( delay_10us(FCV_POS_SERVO); ) and I clear RA0.

Is my problem comes from here ?

Other question : Is the RS232 component uses interruptions ? Maybe my problem comefrom here too. How can I receive data without disturbing my servo motor ?

Thank you for your help !

PS : I wait for the V4 very impatiently !!!

Hello

It sounds like it could be something to do with your software delay. The RS232 is all hardware based and does not use interrupts as standard. Maybe Sean's servo example would work better as this is purely interrupt based and doesnt use any software delays. What value are you using for the RS232 receive timeout.

Thank you for your quick answer !

I try different value between 2 and 200 but I didn't see any change.

I will try to understand the Sean's example program and adapt this to mine.

Have a nice day
