Hello ,I have some questions about MC33774 :
1.How long does it take to do application measurement with 18 cell terminal measurement and 8 AINX measurement? I want to know the the scan time. I looked up it in the datasheet found two times I don't know which one is right.
Application timed continuous and tappmeas
2.After send first capture command how long should we wait to read the measurement ready status? We send the read measurement command between two capture commands and wait about 18 ms to read measuremnt ready status .But it always not ready for the first time . We want to know why and we have to guarantee to get a ready result every time we read. I attached the logistic data file for this problem.
3.We used the BalPause funtion in application measurement When we send the first capture command set this bit to 1 .Then we send the second capture command and change it to 0. But we can only got the voltage data for the first measurement after that the data became invalid value(0x8000). We want to know why and how to fix this problem?
We have checked the time between we sent two capture commands. It is 40ms and it take 660ms to send the next pair of capture commands. Is it OK ?
The attachment file is the SPI data we captured with logisc analyzer for problem 2.
Please help us check it.
Thank you for taking your time help us with these problems.
