I have a High Precision AD/DA board from waveshare with Raspberry Pi 3B (running on Raspbian). With this setup, I get a sampling rate of above 20KPS at my terminal display.

However, I can write only 27 samples in 1s in my CSV file. I am using this Python code for writing to a CSV file. It seems my code is not optimized for writing at a higher sampling rate.

Could you let me know how can I write the data to my CSV file above 10 KPS sampling rate?

Note: I use following statment for writing to a CSV file :

data=str(a[0])+','+str(a[1])+','+str(a[2])+','+str(a[3])+','+str(a[4])+','+str(a[5])+','+str(a[6])+','+str(a[7])+','+str(time.time())

Thanks
