C# and psc (parallax servo controll)

kybr

Hi,

im trying to control my psc directly from my computer with c# and without any basic stamp or anything. im using the serialport class in .net 2.0 , but cant get it to work.
when i send the psc the !SCVER command it just echos it, and i cant get the version number right.
i can controll the servos with the psci program from parallax ofcourse, so my setup is right [noparse]:)[/noparse]

what i got so far is something like this:

void main blablablba
{
SerialPort sp = new SerialPort();
sp.setcomport = COMX
sp.Write("!SCVER\r");
Console.writeline(sp.readline());
}
and that only writes !SVCER\r to my console....

anyone have some example code on how to get the version number just to get me started?
all help appriciated [noparse]:)[/noparse]

What are your other serial port parameters in C#?

i·have tried with·readtimeout 500, writetimeout 500, databits 8 and baudrate 2400.

I know NOTHING about C# so these are just random suggestions. Should the following:

sp.setcomport = COMX

perhaps be pointing to the actual comm port - say COM1 ?

What about parity, what does it default to? Given a choice, NONE is best.

i set i to com4 [noparse]:)[/noparse] the code i wrote was just an exaple.·i think the parity defaults to none.
but i will try to set it just to be sure.

Can you post your code as an attachment?

CJ

do you have a proper level shifter?

Who says you have to have knowledge to use it?

I've killed a fly with my bare mind.

I have used the mentioned SerialPort class without any problems.
