Hello,
I am new to Arduino programming and just need a bit of help. I have recently bought an ARD-LTC2499 24 bit 16 channel board for an Arduino so I can take more analog serial read readings per second and also a wider range instead of just 0-1024. I just need help with the code.
The board: ARD-LTC2499: 16-Channel 24-Bit ADC Data Acquisition Shield for Arduino
The documentation: ARD-LTC2499 Library Reference
The GitHub page: ard-ltc2499/ard2499_example.ino at master · IowaScaledEngineering/ard-ltc2499 · GitHub
My current Code for analog read from a photodiode:
void setup() {
// initialize serial communication at 9600 bits per second:
pinMode(8, OUTPUT);
pinMode(7, OUTPUT);
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(8, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(8, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
digitalWrite(7, HIGH);
// read the input on analog pin 0:
int sensorValue0 = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue0);
}
Github example of the 24 bit board:
#include <Wire.h>
#include <Ard2499.h>
Ard2499 ard2499board1;
byte confChan=0;
void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
Wire.begin();
ard2499board1.begin(ARD2499_ADC_ADDR_ZZZ, ARD2499_EEP_ADDR_ZZ);
ard2499board1.ltc2499ChangeConfiguration(LTC2499_CONFIG2_60_50HZ_REJ);
ard2499board1.ltc2499ChangeChannel(LTC2499_CHAN_SINGLE_0P);
}
byte i=0;
void loop() {
// print the results to the serial monitor:
while(!Serial.available())
{
enumerateI2C(false);
delay(1000);
}
byte retval = 0;
Serial.print("eeprom mac = [");
Serial.print(ard2499board1.eui48Get());
Serial.print("]\n");
Serial.print(" write eeprom[0] ");
Serial.print(i);
retval = ard2499board1.eepromWrite(0, i, true);
Serial.print(" retval=");
Serial.print(retval);
Serial.print("\n");

Serial.print("read eeprom[0] ");
Serial.print(ard2499board1.eepromRead(0, true));
Serial.print("\n");

break;
}
if (i == 16)
{
Serial.print("LTC2499 Temperature");
Serial.print(" = [");
Serial.print(ard2499board1.ltc2499ReadTemperature(ARD2499_TEMP_F));

}
}
delay(1000);
}
byte enumerateI2C(boolean showErrors)
{
byte addr, stat, last_ack = 0x00;
Serial.print("Enumerating all I2C devices\n (Press any key to stop scanning I2C bus)\n-------------\n");
for(addr=0x00; addr<0x7F; addr++)
{
Wire.beginTransmission(addr);
stat = Wire.endTransmission();
if(stat)
{
if(showErrors)
{
Serial.print("0x");
Serial.print(addr, HEX);
Serial.print(": ");
Serial.print(stat);
Serial.print("\n");
}
}
else
{
Serial.print("0x");
Serial.print(addr, HEX);
Serial.print(" ");
last_ack = addr;
}
}
Serial.print("\n");
return last_ack;
}
I need to use this code but for an Arduino instead of their board. Any help would be amazing. Thank you very much.
All the best
