Hi! All.
It's a first time operating the ADS1192 for me.
My question is that I can not measure the voltage 2.42 V or 4.03 V on the pin 9 (VREFP).
From the datasheet on page 22, internal reference,
the output of pin 9 (VREFP) must be the 2.42 v (CONFIG2.VREF_4V = 0) after the initial power-up,.
But I just have a 0.0 V on the pin 9.
Is there a something wrong with ADS1192?
I'm a newbie, so any help would be most appreciated.
p.s.
Maybe, I think it's a related with above question.
Although I should measure the DRDY(pin 22) which is toggled after the initial power-up whatever register value,
but I can't see any signal just DC 3.3 V.
What is the check points with this trouble?
