LJP Posted September 11, 2020 Share Posted September 11, 2020 I need to collect data for vibration analysis. I have a windows laptop, labjack u3-hv, and a mpu6050 accelerometer. I was able to find a way to hook up to my raspberry pi 4 however there is no timer on this so i have no way of actually knowing my sample frequency. I know next to nothing about coding for daq. I was given example code for matlab that should work. When i run the code i get: Opening U3 Unable to resolve the name LabJack.LabJackUD.DEVICE.U3. Error in u3_MPU6050_Example (line 28) [ljerror, ljhandle] = ljudObj.OpenLabJack(LabJack.LabJackUD.DEVICE.U3,LabJack.LabJackUD.CONNECTION.USB,'0',true,0); >> I was given 3 matlab files. One calls on the other two to run. I have all 3 in the same folder. When i run the code my labjack led does not flicker. I need to be able to collect this data so if you recommend different hardware or software that will work better for my application i am open to any input.
