Debugging Programs The DMC-18x2 provides commands and operands which are useful in debugging application programs. These commands include breakpoint, single line step through, and interrogation commands to monitor program execution, determine the state of the controller and the contents of the controllers program, array, and variable space. Operands also contain important status information which can help to debug a program.

Trace Commands 

The trace command causes the controller to send each line in a program to the host computer immediately prior to execution. Tracing is enabled with the command, TR1. TR0 turns the trace function off. Note: When the trace function is enabled, the line numbers as well as the command line will be displayed as each command line is executed. Data which is output from the controller is stored in an output FIFO buffer. The output FIFO buffer can store up to 512 characters of information. In normal operation, the controller places output into the FIFO buffer. The software on the host computer monitors this buffer and reads information as needed. When the trace mode is enabled, the controller will send information to the FIFO buffer at a very high rate. In general, the FIFO will become full since the software is unable to read the information fast enough. When the FIFO becomes full, program execution will be delayed until it is cleared. If the user wants to avoid this delay, the command CW,1 can be given. This command causes the controller to throw away the data which can not be placed into the FIFO. In this case, the controller does not delay program execution.

Error Code Command

 When there is a program error, the DMC-18x2 halts the program execution at the point where the error occurs. To display the last line number of program execution, issue the command, MG _ED. The user can obtain information about the type of error condition that occurred by using the command, TC1. This command reports back a number and a text message which describes the error condition. The command, TC0 or TC, will return the error code without the text message. For more information about the command, TC, see the Command Reference.
