Hi everyone!

I'm trying to get data from a sensor Xsens MT9-B connected through a RS-232 gate and I'm having problems with that. The sensor transmits a total of 25bytes at every 10ms at a baud rate of 115k2 bits/s. The first byte is for Preamble, the second byte is for Address, the third is for MID and the fourth is for Lenght. Then comes the Data that I want in a total of 20bytes. I just want the first 6byte corresponding to AccX, AccY and AccZ (accelerometers). The code in attach must work... but i'm getting nothing and I don't know what to do. Can anybody tell me what I'm doing wrong?


Here is the MT9-B Technical Documentation for more info.

Thank you all!

Hi,

i made a brief review of your code.

I think that your process needs a trigger and you miss a loop for reading the bits. I wrote some comments inside the file.
If it is a pure RS232, then take a look at the RS232RefProj.zip referent project here:

I hope you'll repair that sensor thing :)
