Stamplot adalah aplikasi untuk ploting, indikator, data logging, dan serial data control dari microcontroller. Konfigurasi penuh dari microcontroller atau melalui PC berbasis macro files.
Basic stamp dari parallax sangat favorite, hampir dengan semua microcontroller yang berkomunikasi dengan PC menggunakan serial port.
Stampplot sangatlah serbaguna :
1. 8 sample yang siap digunakan untuk monitoring dan kontrol
2. Mem plot sampai 10 analog input
3. Mem plot 8 chanel digital
4. Men Save file plot dan jpg image.
5. Template data ke dalam ducument lain
dll. bisa dibaca sendiri di situs resminya disini.
Disini saya mencoba untuk menghubungkan Arduino severino dengan Stampplot, karena arduino mendapat julukan stampplot killer.
Dari situs stampplot/makerplot ada beberapa program sample yang sudah bisa langsung dipakai ke arduino
filenya dalam bentuk .txt. Caranya tiggal di copy dan dipaste kan ke arduino program. Dibawah ini programnya :
/*
MP_BasicInteractiveControl
Performs basic interaction with MakerPlot Interactive Interface to
read the slider for the setPoint and control virual LED0 if alarming.
Plots analog values of input and setpoint and
digital values of switches and LED state.
The circuit:
* potentiometer connected to A0.
Center pin of the potentiometer goes to the analog pin.
side pins of the potentiometer go to +5V and ground
* LED connected from digital D9 to ground
* Pushbutton swithes on D2 and D3 going to ground.

}
void flushBuffer()
{
Serial.flush(); // flush serial buffer (may not always flush?)
while (Serial.available()) // manually empty as well, read as long as bytes in there
Serial.read();
}
dari keterangan progamnya ;
* potensio dihhubungkan ke A0.
Center pin dari potensio ke analog pin.
sisi kanan dan kiri potensio ke +5V and ground
* LED dihubungkan ke digital pin 9 to ground ( bisa dirubah programnya ke pin 13, jadi sudah tdk perlu wiring LED lagi )
* Pushbutton switch ke D2 and D3 com ground.
seperti ini :
Kemudian kita upload programnya ke arduino. Ternyata cukup mudah, tidak ada hambatan sama sekali rangkaian dan program bekerja sangat baik. Tidak salah jika arduino dijuluki stampplot killer.
Sample programnya tidak hanya satu, kemudian juga ada video tutorialnya. thanks Arduino & Stampplot
