2. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Operate the Tumbler Using a Jumper Pin  Performance Objective: Using a Cortex microcontroller and EasyC V4, operate the Tumbler successfully using a jumper pin.  Enabling Objectives:  match the following parts to their description and/or function: VEX jumper pin, VEXnet Joystick, USB A-A cable, EasyC V4 for Cortex, VEXnet USB adapter key, USB to serial cable, Default code  sync VEXnet joystick and microcontroller  install VEXnet adaptor keys  describe the process to download the Default code  explain the purpose of the Default code  explain LED codes on the microcontroller and joystick with potential problems

3. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Sync the microcontroller with the Joystick  In order for a VEXnet Joystick to control a microcontroller, they must be synced  To sync you will need a USB A-A cable

4. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Sync the microcontroller with the Joystick  Plug one end of the USB A-A cable into the USB port on top of the microcontroller  Plug the other end of the USB A-A cable into the port on the back of the VEXnet joystick

5. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Syncing  Prop the Tumbler up on a block so that none of the wheels are touching a surface NOTE: This prevents the robot from making unexpected movements  Switch the microcontroller to ON

6. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Sync the microcontroller  The lights on the microcontroller and the joystick will blink and flash  The LEDs labeled ROBOT and VEXnet on the Joystick and microcontroller will turn green indicating that the synchronization is complete  Because the joystick is not switched on the Joystick LED on the Joystick will be red(this is ok for now)  If this is the case, your robot is now synced! (if not, see your instructor for troubleshooting or continue to the troubleshooting slide)

9. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Download the default code  The Default code is what come preinstalled on the microcontroller  The Default code allows you to operate the microcontroller without having to write a program  The Default code will not typically be loaded because most of the applications require a unique program to be written and downloaded

10. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Download the default code  First you will need the orange USB to serial cable  Plug the USB end of the cable into the computer  Plug the serial end of the cable into the port on the back of the joystick labeled Program

11. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Download the default code  Open the easyC V4 Cortex software from the start menu or desktop icon  Begin a New Standalone Project  Select Joystick Project (WiFi)  Click OK

12. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Download the default code  On the top menu bar of the EasyC V4 software select Build and Download  Choose Download Default code  Click yes to download the Default HEX File  Close the window that pops up reminding you to upload the master code

13. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Download the default code  The HEX File will now download onto the microcontroller  Click OK on the window informing you that the file has downloaded  Close the IFI/intelitek loader window

14. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Insert the VEXnet USB Adapter Key  Now turn off the Tumbler.  Remove the USB A-A cable from both devices  Insert the VEXnet USB adapter Key into the microcontroller and the Joystick

15. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Using the jumper pin  Your Tumbler should be operating in Tank mode now.  The left side motors run in the same direction when the left joystick is pushed  The right side motors run in the same direction when the right joystick is pushed  One or more of your motors may be turning in the wrong direction  If so, place a jumper pin into the corresponding digital input of the motor port

16. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Using the jumper pin  If you want to operate the robot in arcade mode (one joystick controls both the right and left motors) place a jumper pin into digital input 12

17. Available at: www.etcurr.comLesson 1.3 – Operate the Tumbler using a Jumper Pin Finished  If after syncing your microcontroller and joystick, downloading the Default code, and using jumper pins if necessary, you should be able to drive your Tumbler around!  Congratulations!
