Connecting Rabbit uP (RCM6700) to Geeknesia



Posted on November 15, 2015 at 1:19 PM


Selama ini platform hardware popular yang digunakan sebagai device untuk koneksi IoT ke geeknesia adalah ESP8266, Arduino, Raspberry Pi dan Intel Galileo. Penulis menggunakan Rabbit uP sebagai alternatif untuk IoT terutama untuk solusi industrial.




Dalam pemilihan hardware harus disesuaikan dengan kebutuhan user. Banyak platform hardware dapat digunakan untuk proyek IoT namun ketika hardware tersebut dipasang 24 jam secara penuh faktor reliabilitas merupakan pertimbangan khusus.

Selain platform yang telah ada Rabbit uP menawarkan kemudahan fungsi-fungsi multitasking dan koneksi ethernet untuk dalam sebuah solusi IoT. Prosesor Rabbit telah digunakan pada proyek-proyek infrastruktur dan teruji di laboratorium lulus uji EMC (EMS dan EMI), power disturb dan lain-lain sesuai dengan standar internasional.

Basic tutorial Rabbit uP dapat di baca di : http://www.rantonic.com/page/1/rabbit-community 

Skenario proyek dasar ini adalah konsep komunikasi machine to machine (M2M) satu arah antar processor Rabbit melalui geeknesia dimana apabila kondisi Led menyala pada satu Rabbit harus diikuti oleh prosesor Rabbit lainnya nun jauh di sana melalui cloud geeknesia. Pengantar proyek ini merupakan langkah awal penulis untuk membuat sebuah industrial IoT gateway dan remote I/O controller berbasis IoT. Komunikasi menggunakan http method 'GET' json format.

Program Rabbit menggunakan Dynamic-C. 

PERHATIAN : Ada beberapa list program yang tidak digunakan, karena di-edit dari koleksi program yang ada...:P...list sebenarnya mungkin lebih pendek namun agak malas membersihkannya....
