Transceiver Communication
•Used two Linx EVM-915-250 transceivers with evaluation boards with breadboard to attempt communication between the two devices

Transceiver Communication
•Fed 4V input supply to Vcc•Created arbitrary analog pulse (square
wave) on function generator as input to transmitting transceiver
•Checked receiving end to observe signal

Initial Results•Function generated signal seen to be fed
through receiving input of one transceiver•Output of same transceiver showed periodic
but non-square wave signal• Input of second transceiver showing same
periodic signal•Thoughts: Square wave signal was not
being sent properly; need to try to use Raspberry Pi to create digital signal to send
•May require more complicated circuitry

Next Step• Use Raspberry Pi tutorials to allow for
complete interface with transceiver/understanding of implementation
• Research Raspberry Pi with LCD screen as possible solution to user device
• Reasoning: Using Raspberry Pi with testing implies knowledge and experience already gained – makes sense to continue using in final product
• Also fairly cheap and looks appealing at first glance
