Thanks a lot Richard for the reply.
I will try to indicate what I am trying to implement .... using my limited English language.
My program applies a correction to a dc power supply by changing the duty cycle of pic pwm output. After that a change command is sent to power supply, I have to read the results from the power supply new output by reading the INA219 data: I must be sure that the reading is refered to the end of conversion to avoid any overcontrol. I also need to average ( about 128 samples ) to get a stable data reading.
I am not able to understand how implement this operation by studing the INA219 data sheet... it could be that I do not understand it well.
Thanks in advance for any help on this matter.
Regards,
Ambro
