BV4205-ADC
The BV4205 is an IC that has 10 channels x 10 bit ADC and is controlled using the I2C interface. The full datasheet is here.
Here is some code submitted by Ian that will control the BV4205 using an Arduino:
Wire.beginTransmission(0x31); // join I2C, talk to BV4206 by Addr 31
(7bit) = 62 BV addr (default).
Wire.send(0x01); //select channel command
Wire.send(0x00); //ch.0
Wire.endTransmission();
Wire.beginTransmission(0x31);
Wire.send(0x02); //do conversion
Wire.endTransmission();
Wire.beginTransmission(0x31);
Wire.send(0x04); //result of conversion
Wire.endTransmission();
Wire.beginTransmission(0x31);
Wire.requestFrom(0x31, 2); //get 2-byte
while(Wire.available() < 1);
for (int i=0;i<2;i++){
data[i]=Wire.receive();
}
Wire.endTransmission(); // leave I2C bus
// combine 2 bytes into 1 unsigned int, value 0-1023
