Mengakses RFID ID-12 atau RDM6300 / RDM630 Menggunakan CV AVR ( Code Vision AVR )

Mengakses RFID ID-12 atau RDM6300 / RDM630 Menggunakan CV AVR ( Code Vision AVR )

              Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara mengekses RFID RDM630 / RDM6300 atau RFID ID-12, sebenarnya keduanya hampir sama output datanya maka dari itu pakai program ini bisa untuk kedua reader tersebut, yang perlu diketahui yaitu output dari reader ID-12 sebelum di filter adalah misal |||F6000657A780## maka dari itu harus dilakukan filter, jadi data dimulai dari pointer nomer 3 sampai 12. Untuk RFID RDM630 atau RDM6300 sama saja tergantung output yang didapat dan dilakukan filterisasi.untuk lebih jelasnya berikut adalah skema dan programnya.

b. RFID Reader ID-12

c. RFID Reader RDM6300 / RDM630

d. Program CV AVR
