    Dear Friends, Thank you for the knowledge you share here. I've worked for quite a while on this library, checked different versions. now I have connected my Neo-m8n module(UART) and Mpu9255 module (SPI) to an Arduino board. I can collect data from the sensors, they look fine. but every time I...

    Youhoo! I have solved the compiler problem, using a combination of Arduino, VS Code, PlatformIO + reconfiguring some compiling flags. Also one should add the ElapsedMillis.h to a few libs. If You guys have any interest on ESP32 , I can share. Now I can compile and upload it. I can read the mpu...

    Hi I really enjoyed the way you guys lead this project. Thank you for your sharings. I am trying to make a stabilized structure, like a pedestal or gimbal. I have used an MPU9250, but need to increase the stability, specially solving the dead zone near 0 degree. so I decide to add a GPS module...
