as already posted before, I have 2 different version of this eval board.
Is it possible to get the scheme of this board?
Hello, I ordered 2 of those from a reseller.
They are more or less the same, except the pcb of the first board I ordered is rounded and the FSKIN and FSKOUT pins are inverted.
I have an Arduino Nano and I connect them using the following instructions:
FSKOUT → D3
GND → GND
VCC → VCC
FSKIN → D6
AREF → D7
First of all, they are all correct?
Then… I tried the androino application from website http://androino.blogspot.com/
And it is not working.
I am using this cable http://www.cdiscount.com/high-tech/accessoires/cable-audio-video-cd23384/f-1062802-auc5412810123384.html
It provides 4 rings.
So I tried to perform some hardware check.
I tested the reception of data incoming from my pc to Arduino using this simple tool:
That allows to modulate bytes in FSK. I am able to receive data correctly. Only the first card can correctly receive data.
Then I wanted to try to send data to my PC from Arduino.
I just connect my speakers or a tweeter to see if something is received… Only the second one is able to do it…
Is it necessary to build a custom cable to cross microphone and speaker lines?
No public wish lists :(
