I am using homemade pc sw with Arduino (duemilanove 328). Arduinos own Ide works fine but my program does not. To check my settings first, I'd like to know what exact serial bus settings with it are.
Baudrate =9600
stop bits =1
parity=none
What else?
Have you problems using Visual basic with Arduino?
Baudrate: whatever you set it to in setup with Serial.begin(xxx) (Serial.begin() - Arduino Reference)
8 data bits
No parity
1 stop bit
Loads of people have used VB, Java, Python and probably every other programming language under the sun to talk to the Arduino. Try here for some examples: Arduino Playground - InterfacingWithSoftware

Stop or parity bits are not mentioned on (Serial.begin() - Arduino Reference) only baud rate. Arduino Playground - Java this is interesting and there is info about rest of the settings.
Not mentioned because (8 data bits, No parity, 1 stop bit) these settings are 'hard coded' in the Arduino serial core library function.
They can be changed by setting/resetting bits in the AVR processor's registers that control the serial hardware, but you would have to find the details in the processor's data sheet and set them up yourself in your sketch.
Only the baud rate is a changeable parameter in the Arduino supplied serial function.

Hello all, I have been trying to use an analog gauge to display cpu load like this Arduino Analog Gauge uchobby one (not allowed to use links, sorry)
Problem is that one tutorial is based on a former DIYlife tutorial ( show-pc-stats-on-analog-gauges)
and I am not sure which steps the arduino actually replaces. I have manages to link the gauge and arduino to PC via hyperterminal. I can get the needle to respond only to hyperterminal input but not input from LCD smartie5.4 (thus no cpu load display).
Is there anyone out there who has actually succeeded in doing this who can clue me in? Just trying to do a Hot Rod PC case mod and this is the only thing holding me back. Any help is appreciated!!
