Question

I just got my Pittle and after installing all the nesesary drives I tried to compile WriteInstinct.ino the IDE gives an error that says "Error compiling for board Arduino Uno."  what board is it?

Hi @Ben so let's do it step by step.

Something is wrong with the content of MPU6050 library folder (C:\Users\SOL_K\Documents\Arduino\libraries\MPU6050). It should contain those files:

Seems like you have there something else. Can you remove the folder and carefully add it one more time? Here is the steps in 4.2.2: https://bittle.petoi.com/4-configuration

Just to clarify, after completing instruction 4.2.2 you should have MPU6050 folder as above and the \Arduino\libraries\I2Cdev folder like this:

Try this and then we can tackle connectivity issue

@Ben Good news! To check if you have proper drivers for the board please see in Device Manager. See if you get anything like CH340 when you connect USB cable with programmer attached (programmer to Bittle connection not required)

If not then install driver from: https://translate.google.com/translate?sl=auto&tl=en&u=http://www.wch.cn/download/CH341SER_EXE.html

Thank you @Dobromir. That fixed the compile problem, I had to delete the directories for the two libraries I had already installed, after installing from your link it worked. Now I just have the problem of the Arduino IDE not seeing the Bittle port. After work I will try using the Bluetooth board to connect to Bittle.

You need to remove previously installed I2Cdev library. Ideally, you could remove all the libraries under Documents/Arduino/libraries and reinstall the libraries used by OpenCat.

Hi Dobromir, I did what you suggested and it still fails to compile.

Here are is a screenshot of the new directory:

and here is a shot of the IDE showing port grayed out when the Bittle is plugged in:

here is a picture of Bittle plugged in: Bittle does make a buzzing noise a few seconds after its plugged in (not sure if bad board?)

This is the error message after the directory move:
