While developing code for my project, I started realizing that I am running out of space. I started commenting out random lines of code to see how much size they take up and I found out that devStatus = mpu.dmpInitialize(); takes up 21% alone of my program space!
I want to reduce that, so I found the function in the MPU6050_6Axis_MotionApps20.h library which I have attached below. My question is what exactly in the uint8_t MPU6050::dmpInitialize() function is taking up so much space? Is it possible to reduce the program size of this function?
My project uses an MPU-6050 gyroscope and accelerometer hooked up to an Arduino Micro.
It looks like most of the MPU6050 libraries include something like 2.5k of binary code and parameters for the MPU device, but that should only be about 10% of program memory space of a ATmega328...
I am using the library by I2CDev, and I am also using an Atmel32u4, which has a slightly larger bootloader size than the 328. But when I compile the code, with and without that line, I get a difference in program size of 6064 bytes. That seems like a lot!
