General description

The goal of this project is to provide communication between PC and vehicular platoons using specifications of Zigbee network stack as a base.

Oscilloscope settings

  • Use trigger in Normal mode, set it to descreasing edge of MRDY signal, timescale 50 us and y scale 1V, trigger to 1.5V. After using reset sequence, the data comes after cca 780-800 ms.

Function description

Notes

  • After reset sequence to measure the first initial communication on the oscilloscope, wait for cca 500 ms. The first drop in SRDY is just a disturbance, not the indication to be ready to receive data.
  • B1 USER: User and Wake-Up button connected to the I/O PA0. On SmartRF05 Evalution Board: P10-19.
  • LD7 detects MRDY position: if MRDY is low - LD7 is on, if MRDY is high - LD7 is off.

Random ideas

  • There are several ways for applying power to the SmartRF05. The power source can be selected using the power source selection jumper on header P11 (1-2 for battery, 2-3 for USB). SRDY signal doesnt change according to expectaion if USB was selected as power source.
