Eto na. Dumating na mga RF modules ko. Sa sobrang bagal nung unang order ko, umorder na ko sa iba so may 5 akong sobra. Yung isa binili na ni Glutnix.
Since the RF module runs on 3.3v as per datasheet I've implemented some levelshifting. Kinaya naman ng voltage divider so I used 2 resistors 4.7k and 10k. All output pins going to the RF module from arduino goes to their own voltage dividers. The output of the RF module goes directly to the pin of arduino. Arduino will still see 3.3v as logic 1 so no need to have a 3.3v to 5v level shifter.
The module uses SPI so medyo madali na, and may arduino library.
The test setup is 3 arduinos.
One Arduino is set as NodeID#13 (I can specify any node number). This is used in the data packets. I've set this to send a packet every 500ms.
A second Arduino is set ast NodeId#17. This one will send a packet every 100ms.
A 3rd Arduino is the main receiver, it will also send a packet (para manggulo ng airwaves).
Eto yung video ng capture of packets. Note that there's a sequential packet ID so I'll know if there's a missing packet or not.http://screencast.com/t/5rM39PBqtKq
