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

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
Available at: www.etcurr.com Lesson 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

Syncing
Prop the Tumbler up on a block so that none of the wheels are touching a surfaceNOTE: This prevents the robot from
making unexpected movements Switch the microcontroller to ON
Available at: www.etcurr.com Lesson 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)

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
Available at: www.etcurr.com Lesson 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

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
Available at: www.etcurr.com Lesson 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
Available at: www.etcurr.com Lesson 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

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

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

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

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!
