Title: A10 lime connect microphone
Post by: joinsnc on June 12, 2014, 04:13:57 PM
I need help to connect a microphone to a10 lime.

I have seen that there is a micin1 on gpio1 and linein on gpio4.
I have bought this microphone that is amplified: http://www.adafruit.com/products/1063 (http://www.adafruit.com/products/1063).
It has three pins (1 ground, 2 out, 3 vcc)
I have made this connections:

1)
mic pin 1 --> ground a10 lime
mic pin 2 --> micin1 a10 lime
mic pin 3 --> vcc 3.3 a10 lime

2)
mic pin 1 --> ground a10 lime
mic pin 2 --> lineinl or lineinr a10 lime
mic pin 3 --> vcc 3.3 a10 lime

neither 1) nor 2) have success.

Can someone help me to correctly connect this microphone on a10 lime?
I need some other hardware?

thanks in advance.
