Oke Trik Open Port Rxtx Windows 7


Hai sobat IoT yang super canggih ide-ide kreatifnya..
Diblog kali ini saya akan memberikan tutorial untuk membuka  RXTX di Windows 7. Pengalaman pribadi saya dan tim dulu sangat kesusahan dalam membuka RXTX  atau Open Port RXTX di windows.  Setelah berusaha saya berhasil membuka atau Open Port Rxtx.
Setela kita berhasil Open Port RXTX tentu sangat membantu kita untuk mengambil nilai yang di Arduino untuk kepentingan pengolahan data atau kepentingan lainnya. Berikut adalah tutorial Open Port RXTX di Windows 7:
  1.  Buka rxtx di windows 7
  2. Download library rxtx

Untuk Windows :
RXTXcomm.jar dicopy ke tempatinstalljdk\jre\lib\ext
rxtxSerial.dll dicopy ke tempatinstalljdk\jre\bin
rxtxParallel.dll dicopy ke tempatinstalljdk\jre\bin

rxtxParallel.dll dicopy ke tempatinstall => window/system/system32
3.Buka NetBean IDE 7
4.  Coding
