B4R Question help with console command

[electronik54]

hi guys..
i am new with arduino.

i was wondering if it was possible to send commands to arduino over serial comm... for example if i type setDo 1 1 on hyperterminal connected to arduino it will set DO 1 pin to high..

all that i was able to do was read just a single character. i need is some help or some push in right direction.

Are you using AsyncStreams to read the data?

hi E54
It is better to be specific.
1. Read the string in Arduino
2 or the return value in B4R
Etc etc.
Also sometimes 2 line code snip will give us even better idea of what and how you did it.

OK I'll assume that you send the string setDo 1 1 with B4R to the arduino.

the arduino code must read ALL characters in the string before it 'parse' the line into variables. setDo, 1 and 1.

secondly it is not good programming practice to separate values with spaces as it could limit future features. We use the '~' as seperator because the chance of that in a 'sentence' is about NIL.
