Hi all, searching on web i found the code for implementing a Kalman filter. I'd like to implement it in codesys in ST, but im not so skilled in coding so i dont know how to translate that code in ST. Can someone help? This is the code: float kalmanFilter(float accAngle, float gyroRate) { float y, S; float K_0, K_1; KFangle += DT * (gyroRate - _bias); P_00 += - DT * (P_10 + P_01) + Q_angle * DT; P_01 += - DT * P_11; P_10 += - DT * P_11; P_11 += + Q_gyro * DT; y = accAngle - KFangle; S = P_00 + R_angle;...

thank you Thomas! I correct with the full name of the function and it works!

Hi, i'm trying to use a function from oscat library. If i use it with CFC it works, but in ST not, for syntax errors or something similar. I get the error "oscat_basic.ATAN2" is of type FUNCTION and cannot be instantiated. Can someone tell me the error(s)? Thanks, BR

Hi all, someone can help me to understand why PCF8591 doesn't work? I tested with python and it works, so connection are ok and i2c works, but in codesys i dont see any value, I add some image maybe someone knows where is the problem. I used the example https://forge.codesys.com/forge/talk/Runtime/thread/8981ce928a/#0518 , installed the device (by creating the .devdesc.xml file), installed the library and run. There are any parameters to change or some operation to do before? I also test MPU6050...

I not sure but probably i solved disabling remote GPIO in RPI setting.

Hi all, i have some problems with GPIO on RPI4. I set-up a simple system to test codesys but it doesn't work. I have only 1 input (pushbutton) and 1 out (a led). I also test the MPU6050 and it works correctly. Testing with python everything work fine, but with Codesys can't see the input when i push nor the output using a blink module. I started with the example GPIO.project, i change the GPIO board with the B+, i set GPIOs parameter input\output for the related channels, i declared in I\O mapping...

it works, ;-) Thank you,

see now that my codesys downloaded on 23 @19.55 was 3.5.16.10 Downloading last version, thank you, BR

Hi Edwin, i download and flash an sd with the image [ ] 2020-05-27-raspios-buster-armhf.zip i installed it, everything seems ok,but the issue persist, after few second raspi stop the connection. What's wrong ? Thanks, BR Matteo

Hi all, i tried to do some research on forum but can't find any operative suggest on the possibility to integrate a gps module into rasperry PI and manage it with codesys. Does anyone knows if there are documentation\library\example project or something to start? thanks, BR Matteo
