    Cool on the LC's will eventually have to pick a couple up. Anyway was still in the process of doing debugging - turns out two things - the 3.2 breakout board I put together yesterday I missed some solder joints. ...

    Thanks - think I may have found the problem but no guarantee. Have more debugging to do - going to test it on my old reliable setup up that I have been using except I am going to change to wire1 since wire is tied up.

    Ok.. slave.events is there and I just uncommented the line out in the master for teens_gpio.events. Hoping that was it - have to check sda/scl now. Oh boy, nothing ever works out of the box for me :) but on the other...

    Got it. Oh, one more question, where does i2c address 0x22, come in? Reason why I am asking is that I am not getting anything from i2c and trying do some bebugging :) and SPI transfer is awfully slow?

    yeah I forgot. So I would do: { Threads::Scope scope(MST_QUEUE); Wire.beginTransmission(0x22); Wire.write(text, sizeof(text)); Wire.write(text1, sizeof(text1)); Wire.sendTransmission(); } and...

    Had to ask. I recognized the test sketch and wanted to reduce it to its basic form - easier to understand and not get confused. Yeah I noticed how it mimics the library. Going to give it a try today and let you...

    Tim - know I put a lot into the last message. But I did trace what was causing the doubles - it was the MS5637 pressure sensor causing the problem. Depending on the OSR selected there is a built-in delay (per...

    MS5637 pressure sensor update: 1. No osr level works at 200hz. 2. At 100hz the max OSR that you can use without double hits is OSR_1024. Mike

    UPDATE: Without the Baro at max OSR I can run the IMU at 200 hz without a double. Going to play around with the OSR to see where it impacts

    I'll give it a try after I play around with uNAVIns a little more. There are a couple of test cases I want to go through on that. I still want to get back and figure out to best use the SPI_MSTransfer with the other...

    No I haven't. Don't think its a NVIC issue. Baro's are notorious for taking time to get an stable accurate reading. You have to use a high over sampling rate but that comes with a large delay in getting a reading. I...

    Now back to the program. I do something similar to "parameter " when updating the baro sea level pressure. Basically, all I do is in the case block for the command I do Serial.parseInt() and then you can test on the...

    Hi Tim The T3.5 is running at 168Mhz as well as the slave. I just changed to 100Hz updates for the IMU and still getting doubles, here is a sample: ---Lp#:21771 IMU#:70 > 1S:100030800 > IMUcc:683196 >> Mcnt:64 >>...

    Hi Tim, By the way when I said I was running at 100hz I was wrong. Somewhere along the line I must have changed it. The problem I was seeing was because I was running at 500hz :). Changed it to 200hz and running as...

    Will give it a try later. I am only running at an SRD of 9. By the way are you printing odt.average() or just odt?
