Arduino and External ADC ADS1015 samlping rate?

[nagesh15]

Hello all,

              I am using Arduino Uno and external ADC ADS1015 for data acquisition. I want to set the SPS of ADS1015 to 3300sps. Is it possible to sample that at this speed? Currently, it is sampling at approx 100sps. How can I increase SPS in Arduino, or do I need to change the microcontroller? Is there any microcontroller available that is faster than Arduino and possible to acquire data at a high SPS rate (more than 3000sps)?

Hardware: Arduino Uno and ADC ADS1015

Software: Arduino software

Hi Nagesh15,

in this case your speed is not limited by your MCU but by your communications bus between your Arduino and PC.  I’m guessing you are using serial comms?  Maybe consider try using an Arduino with Ethernet that is comparable with Linx.  Also would you be willing to share your code?  I have been having many issues getting my ADS1015 working in Labview.  I continually get an output of all 255’s with nothing connected.

Thanks for your time!
