For this version, any number would do // motor_no : ID in which the motor has been connected // // Description // Arduino board does not deliver enough power, so it is necessary to use a H-bridge circuit/IC to control the motor. There are several types of H-bridge IC that do not all operate on the same principle. For example, the L298 requires the use of a PWM signal with current sense. The L293 uses two PWM to set the speed and direction. Ready-to-use Shields are also available. // // Remember that the PWM is 8-bit (0 to 255). The input of the block could accept any value, but it would saturate at +- 255. // // Examples // ok = open_serial(1,9,115200) // cmd_dcmotor_setup(1,3,1,9,10) // Setup DC motor of type 3 (L293), motor 1, pin 9 and 10 // cmd_dcmotor_run(1,1,255) // sleep(1000) // cmd_dcmotor_run(1,1,-255) // sleep(1000) // cmd_dcmotor_release(1,1) // close_serial(1) // See also // cmd_dcmotor_setup // cmd_dcmotor_release // // Authors // Bruno JOFRET // code_sent="M"+ascii(48+motor_no)+"1"+ascii(0); write_serial(h,code_sent,4); code_sent="M"+ascii(48+motor_no)+"r"; write_serial(h,code_sent,3) endfunction

\begin{document} The third and final part of the semester project focuses on the actual generation of formatted output from Latex input. There are 5 tasks for this project, with the divisions given to differentiate between required work point totals and bonuses. Note that you {\it MUST} utilize the {\it union} command to redefine the parsing stack in yacc bison. This project is worth 100 points with up to 15 bonus points. The tasks for the project are: \begin{enumerate} \item Basic Text Processing Capabilities (35 points total), including: Section Subsection Table of Contents (5pts), Line Spacing Single-Double-Triple (5pts), Page Numbering Styles (2.5pts), Horizontal Vertical Spacing (2.5pts), Italics Roman Fonts (2.5pts), Paragraphs Noindent (2.5pts), Right Justification (10pts), and Begin End Single Blocks (5pts). \item Advanced Text Processing capabilities (55 points total), including: Itemize Blocks (5pts), Enumerate Blocks (5pts), Center Blocks (5pts), Verbatim Blocks (5pts), Tabular Blocks (10pts), Table Blocks with Refs Captions (5pts), and Relevant Combinations of Blocks (20pts). \item Documentation, Log, Testing (10 points total). \item Bonus A: Nested Blocks within Single Environment \item Bonus B: Full-Blown Verbatim: All possible Latex commands that are embedded in a verbatim block (e.g., backslash, blocks, etc.) are ignored. \end{enumerate} The directory {\it home ug1 demurjs CSE244.SP94 Part3} contains a number of important files, including: \begin{verbatim} latex.l : A common latex lex file. latexp3.y : A yacc specification where verbatim works. latexp3code.y : A yacc specification with sample code generation. util.c : A number of C utility routines. generate.c : A number of routines used to generate code. \end{verbatim} Portions of these and other files will be discussed in class. The third part of the project is due on Monday, May 2, 1994. Please hand in the following: \begin{enumerate} \item The yacc bison specification for tasks 1, 2, and 3. DO NOT HAND IN C files! Also include copies of any relevant C files. Make sure that these are well-commented, clear, and organized. \item Documentation of your solution that includes: (1) any assumptions that you make regarding the output format and style of your document (e.g., margins, page number locations, handling underlining, etc.); (2) a log file that keeps track of all of your major design steps, implementation strategies, problems encountered (with lex yacc) and their solutions, aspects of the project that were easy hard, changes that were made to the grammar, etc. The key word is MAJOR design steps. NOTE AGAIN THAT YOUR DOCUMENTATION MUST BE GENERATED USING YOUR LATEX COMPILER!!!! \item Test cases and test results for all tasks, clearly marked and organized. \item The directory location for your files and detailed compilation instructions. \end{enumerate} {\it IMPORTANT:} Do not open your directory for access by the world until 7:00 p.m. on May 2. \end{document}
