Arduino Pro Mini to AR1000 FM Receiver Module over I2C

Wireless & IoT

Hey Folks,

Does anybody have any info regarding their experience trying to get the ar1000 working with arduino’s wire library? I’ve been trying to deconstruct the avr example code as I also try to make sense of the datasheet (has anyone seen the register map?). I can post code if anyone wants to take a look. Wondering also if anyone has experience with receiver modules by other manufacturers. Any and all info would be helpful.

Best,

~GM~

Here’s a snippet of code attempting to initialize the receiver. This is the first time I’ve used the wire library, so please let me know if you see glaring errors.

#include <Wire.h>

byte lbyte=0;
byte hbyte=0;

void setup(){
  delay(3000);
  int regval[18]={0xFFFF,0x5b15,0xf4b9,0x8012,0x0400,0x28aa,0x4400,0x1ee7,0x7141,0x007d,0x82ce,0x4f55,0x970c,0xb845,0xfc2d,0x8097,0x04a1,0xdf6a};
  Serial.begin(9600);
  Wire.begin();
  Wire.beginTransmission(0x10);
  for(int i=1; i<18; i++){
    hbyte=regval[i]>>8;
    lbyte=regval[i]&0x00ff;
    Wire.send(byte(i));
    Wire.send(hbyte);
    Wire.send(lbyte);
  }
  Wire.send(byte(0));
  hbyte=regval[0]>>8;
  lbyte=regval[0]&0x00ff;
  Wire.send(hbyte);
  Wire.send(lbyte);
  Wire.endTransmission();
}
void loop(){
  digitalWrite(13,HIGH);
  delay(100);
  digitalWrite(13,LOW);
  delay(100);
}
