"Hi Kevin,
We are counting that You will find the reasons of those self tests differences.

MP 2128G2 Heli Sensors calibration

Hello Everyone!I try to run the autopilot MP2128HeliG2 in trueHWIL setup. After load a simulation to the xPC Target computer I run the Autopilot and I got a lots of errors from sensors. The message…Continue

"Hi Janusz,
I don't know why your ST1 only rises four times and your pitch gyro signal rises three times while mine rose one time and fell 6 times. I will investigate this further when I have time.
"The J44 plug we have from fixed…"
"Hi Kevin,
After self tests it's look like the ST2 is the same. The ST1 rise only four times. And the Pitch gyro signal only rise three times. You can see the exact shapes in the attached bitmaps.
The J44 plug we have from fixed wing setup…"
"Hi Janusz,
"I was wondering about this connection of S5. Because i didn't have anything connected in S5 on servo board, so maybe this is the source of this Fatal Pitch gyro error. I checked manual and I saw that for Servo 5 I have to…"
"Hi Janusz,
Regarding the POST pitch gyro failure issue:
I'd like you to check both the self test (ST) signals and the pitch gyro signal.
1) J21/J23 pin 3 is ST2. It's normally 0 and goes to 5 V three times during the POST "testing…"
"Hi Kevin,
This appoach works and Matlab model were built correctly, so thanks again for Your help.
"And since this is a helicopter, servo 5 is collective pitch so make sure to make the S5 connection on the servo board."
I was…"
"Hi Janusz,
"Could You maybe know where we can find the configuration options for this xml files?"
This is because the .mat file contains the path. The .mat files are temp files that you can delete.Please delete all the .mat file and…"
"Hi Janusz,
"So do we need to invert the direction of those servos?"No, I wouldn't worry about that since it's flying fine." And then simulate fixed wing finally could take off. It traveled correctly between waypoints, and I…"
"Hi Kevin,
In the mean time i tried to run this verified model for fixed wing autopilot directly in Matlab simulink program. And when I built the project it didn't finish because of some error during creating xml file. Could You maybe know…"
"Hi Kevin,
When we bought autopilot MP2128HeliG2 in this year we got also the 400Hz servo-board so I connected it to the whole setup. We still have the older servo-board for the fixed wing autopilot so we can switch it if it is needed. When I changed…"
"Hi Janusz,I did not realize you are using the new 400 Hz servo board. With this, the fast servo mode MUST be set to fast servos 1-10. So go in to your VRS, flight B tab and set fast servo mode = 5 - Fast servos 1-10. Then transmit that VRS to your…"
"To make results of this experiment more clear, when I used any of those four sliders the xPC values didn't respond. They didn't react for seting zeroes, and also the values didn't stabilize when sliders goes to the left or right side.…"
"Hello Kevin,
When I follow with this procedure i didn't get any visible reactions from Target PC readings. The Ailerons and Rudder swith between -30 and 30, Elevator was constantly 30, and Throttle swich between 0 and 1. I checked…"
"Hi Janusz,
I'd like you to check the servo outputs from the autopilot which are input to the digital interface.
Perform the standard startup procedure.Connect in Horizon and wait for ready.Do not click POWER ON in THWIL center.Disconnect…"
"Hi Kevin,
I used the parameters file from previous positive callibration proces. You were right, i used the older vrs file with similar name. Now i checked cerfully the file names and uploaded the correct one. During simulation,…"
"Hi Janusz,
Did you transfer over your calibration factors from when you did the calibration awhile back?
In the POST log, I see that the default report is the GGGG (GPS report). But in the VRS that you were supposed to…"

Good Day,
How is everything with you, I picked interest on you after going through your short profile and deemed it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on:(mrsstellaabudheir@gmail.com ) for the full details.
Have a nice day
Thanks God bless.
Stella.
