Reading Pan Angle from terminal.c
I am confused as to how to properly read Pan Angle in the terminal.c file inside of auto user_routines.c. Do I define
the Pan_Angle parameter inside of terminal.c or inside of user_routines.c Do I use an extern static unsigned int statement inside of terminal.c and still use another statement in user_routines.c? I tried to look through the code and did not find examples. 1) I have added a statement right below where Kevin is outputting Pan Angle in the print statement to calculate Pan_Angle. printf(" Pan Angle (degrees) = %d\r\n", (((int)N_SERVO - 124) * 65)/124); (Pan_Angle= (((int)PAN_SERVO - 124) * 65)/124); 2) Inside of terminal.c I have added static unsigned int Pan_Angle = 0; 3) What about inside user_routines.c where I actually want to be able to read the Pan Angle? A little confused with C-coding standards, |

Re: Reading Pan Angle from terminal.c
If you are declaring the variable outside of a function in terminal.c, make it an unsigned char.
In order to be able to access the variable in user_routines.c, put a Quote:

So, I have done the following and received the following error message.
Inside of terminal.c I have placed 1) unsigned char Pan_Angle Inside of user_routines.c I have placed 2) extern unsigned char Pan_Angle and I received the following error message. user_routines.c:566:Fatal [151] -internal p opulateExternalReferences() - symbol 'Pan_Angle' is not an external reference. |

Re: Reading Pan Angle from terminal.c
Do you have the definition of Pan_Angle defined within a function? Defining it outside of any function in terminal.c will make it global. Define it after the #include statements.
