softtoytrev 0 Report post Posted November 14, 2018 There are a heap of on-line sketches that require using your I2Cdevlib and the MPU-6050 libraries, so having installed the I2Cdevlib off the GitHub website, I get the above message when trying to compile to a Arduino Nano that requires the I2Cdevlib and the MPU-6050 libraries. I have removed the I2Cdevlib several times, and restored the libraries to different locations, however I now always get a message that says "include jendef.h file not found or not installed compilation terminated". I originally downloaded the I2Cdeclib in August and used the library with no problems, however I re-downloaded the library recently and find that it is now unusable. Can anyone help me with this issue please? Hutch_s_I2C_Accelerometer.ino Quote Share this post Link to post Share on other sites
