I assume you are having problems with protocol that the sensors require. I’ve set the pullups with the suggested resistance values 1.

You just need to make sure both devices can handle the baudrate, which is always set by the master. Previous topic Next topic.

I got that yesterday You don’t need to match baud rates. You should be able to follow this and convert it over to MP. Is that the normal thing to do?

I need help!!! How to read from CMPS03 with HC12 thru i2c

Then I looked at my code and it was really 50KHz from a test I did the other day.

The Beagle analzyer provides a high performance monitoring solution in a small, portable package. Thu Sep 01, 5: Wed Sep 07, I thought it would take me one or two days to set up the compass, but it’s taking more than two weeks already I was measuring the signal duration on the oscope and it was giving me a frequency of 50KHz Also, after reading a couple of other posts involving problems using I2C, I’ve just made a note to myself to check the following: I’ve suggested that mE could produce a software product used in conjunction with the easyPIC to do this.
