Freematics One


I bought a freematics one along with emulator.

I tried to upload the emu327.ino( on the free one device but I got this error.


Arduino: 1.8.0 (Linux), Board: "Arduino/Genuino Uno" /home/e0000081/Arduino/Learned/L1/L1.ino: In function 'void loop()': /home/e0000081/Arduino/Learned/L1/L1.ino:88:35: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings] sendData("$OBDATGRD\r", 10); ^ Sketch uses 2994 bytes (9%) of program storage space.

Maximum is 2048 bytes. avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied Problem uploading to board. See for suggestions.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. *******************************************/
