−	Make sure that the auto-generated code is created as intended and that you don't run into a DBC or the auto-generation issue. In other words, the auto-generated code should compile on all controllers.

−
−	Your GIT repositories will be audited to assess how much contribution you have made to your GIT project. At minimum, there should be something checked-into the main branch to demonstrate that you know how to use GIT.

−
−	~~=== Assignment ===~~
−
−	Write a schedule that is a list of your team's milestones. This is a tool for you to assign responsibilities and deadlines for your project's milestones. In general, this should list out when the team as a whole expects a certain functionality to be delivered.
−
−	The grading will depend on how well you have assigned your milestones and if the goals are measurable. For example, milestones such as "interface sensor and send sensor data over CAN messages" and "add a filter for the sensor data" are measurable goals, whereas, "interface sensor", and "send data" are too generic and un-measurable goals.

−	~~= CAN TX / RX using Auto-gen code =~~
−
−
−	~~=== Assignment ===~~
−
−	~~Work in groups of 2 by assuming one board is the DRIVER while the other board is the MOTOR or SENSOR.~~
−
−	~~The objective of the assignment is to demonstrate CAN data handling using the auto-generated code. Follow these steps:~~
−
−	*Define a DBC message that your controller sends (TX)
−	*Define a DBC message that your controller receives (RX)
−	*Attempt to recover the CAN Bus (from Bus OFF) at 1Hz (both Boards)
−	*Send the TX message from BoardA at a fixed frequency, such as 10Hz
−	*Attempt to receive the RX message (on BoardB) at the designated frequency, and light up an LED when the message enters the MIA state
−	*Prove that the MIA handling is occurring as intended (simple LED test by disconnecting the board that sends you a periodic message).
−	*Prove that valid data is being received and reacted upon (such as displaying received sensor reading on the LED display)
−
−	This is a powerful assignment that demonstrates how to send and receive data using the auto-generated code that is derived from your DBC file. This will be the stepping stone of the overall CAN communication that will occur in your project.

−	* There should be a "Red Link" that I created for you to edit; Red-link means that "This Wiki article doesn't exist yet"
−	*: Make sure you are logged into the SocialLedge Wiki, and then click to edit this page
−	*: Rename one of these bullet points to your project name (use a wise name for your project):
−	*: Tag your project with "F17" or similar, such as:
−	*: <nowiki>[[F17: Spartan and Furious \| F17: Spartan and Furious]]</nowiki>
−	*: Click to save this page
−	* In a separate window, [http://socialledge.com/sjsu/index.php/Autonomous_RC_Car_Project_Report_Template browse to this page], click "Edit" and COPY the entire Wikipedia markup
−	*: Now click on the red link that belongs to your project
−	*: Paste this template for your project, and work on setting weekly goals in your schedule section.
−	*: Save the template
−	* Now go back to your project's Wiki page, click "EDIT"

−	~~= Periodic Scheduler =~~
−
−	~~=== Assignment ===~~
−
−	~~INDIVIDUAL HOMEWORK:~~
−
−	~~Easy homework, use the periodic tasks to add two functions that they call, run your program, and then do the following:~~
−
−	*Modify main.cpp to configure the periodic scheduler, and leave the terminal task present that you will use later in the assignment
−	*Design a Software based "filter". The simplest one could be to average a few readings but read and research more on Wikipedia (they even have Psuedocode)
−	*Add the two new "Sensor" periodic callbacks, one at 1Hz, the other at 10Hz
−	*: In the 10Hz callback, design a Software filter to filter the Light sensor readings
−	*: In the 1Hz callback, print out the filtered sensor reading.
−	*Do more experiments with the "Logging" capability
−	*: Log some data using LOG_INFO() or similar message from file_logger.h
−	*Use "info 5000" command to see CPU utilization for 5 seconds.
−	*Use "cat log.csv" to view the log file data.
−
−	~~Attach your output to Canvas along with your code.~~

−
−	~~= LED Switch =~~
−
−	~~=== Assignment ===~~
−
−	~~Work in groups of 2 and use existing API under '''gpio.hpp''':~~
−
−	* Interface an external LED (such as P2.1) to "Board A", which we will refer to as "LED Board"
−	* Interface an external switch (such as P2.2) to "Board B", which we will refer to as "SW Board" (switch board)
−	* Connect the LED Board and SW Board together using "Port 2"
−	*: Example: P2.0 of LED board connects to P2.0 on the SW Board
−	*: Do not forget common ground
−	* LED board Software is simple, whenever P2.0 (which is interfaced to the SW Board) is detected HIGH, light up its LED (on P2.1), else turn it off
−	* On the SW Board, use "External Interrupt" API (eint.h) to detect when the switch gets pressed
−	*: The callback should simply turn a flag (global variable) to true
−	*: The callback '''''MUST NOT POLL''''', and '''''MUST NOT DELAY''''', and '''''EXIT IMMEDIATELY''''' since it is an interrupt function
−	*: Use period_init() function to initialize the callback. This initialization function is only called once before starting the RTOS
−	* On the SW Board, use the periodic callbacks, and when the flag is true, toggle the P2.0 for at least 500ms
−	*: Turn on the periodic scheduler at main.cpp
−	*: Deploy your code to periodic_callbacks.cpp (like 10Hz function)
−	* Bonus points: Use a binary semaphore in the interrupt, and have the 10Hz task wait on this semaphore with 0 ms block time. See the FreeRTOS video about the binary semaphore
−	*: Note that if you use a periodic callback, you will have to use zero block time for the semaphore since you do not want to block in a period function.
−	*: '''[https://www.youtube.com/watch?v=grXuVMttVuU: Binary Semaphores]'''
−
−	~~For the demo:~~
−	* The SW Board should detect its switch press by an external interrupt and toggle its P2.0
−	* The LED Board should detect its own P2.0 and light up the LED
−
−	This assignment demonstrates the use of external interrupts, and how to interface different boards together. Furthermore, you should have learned the concepts of different tasks that you can run in FreeRTOS. In general, you should never have to poll for events, and you should use interrupt functionality as much as possible. Turn in ONE SUBMISSION per group with the following:
−
−	~~Only turn in the relevant source code, such as main.cpp~~
−	~~Indicate at the top of the file who you worked with. (Do not have the other person turn in anything)~~
