I am trying to create c++/c program to AnalogRead using and ADS1115. I have seen that wiringPi has support for ADS1115 but i could not find any sample program to start with. Can anybody link guide me to some sample code to read from an ADS1115.

  • Jack, I am a python guy and only know about python programming examples, such as those by AdaFruit: github.com/adafruit/Adafruit_Python_ADS1x15/blob/master/…. AdaFruit uses libraries so it is easy for newbies to start quickly. I usually go to their library's GitHub page and learn how they write the init, setup etc, and DIY my own python programs. I usually think that start prototyping with python, and later "translated" it to C++ is time efficient.

  • i am trying to benchmark the language first before fully committing since i would need as fast as possible sampling. I know that python is inherently slow compared to C++ thats why im trying to check if by how much.

  • I agree with your approach. But I vaguely remember ADS1115 max SPS is less than 1k, so it is for sure the bottle neck, and using C++ won't help.

  • I might wrongly remember the max sps of ADS1115. Just now I checked another 24 bit ADC ASD1256 and found it is 30kSPS. I also remember that 8/12 bit ADC can do 2k SPS, but not sure.

  • datasheet say its programmable 8-860 SPS, python produced me only 50 samples in 1 second(by default i did not try to change anything yet) and i need around 300-400. so im seeing what C++ can offer. i would prefer coding it in python too since it makes the other parts of the program easier.

I have found this github that forked the arduino's ads1115 library to be compatible with the raspberry pi.
