Vexnet 2.0 (white keys) no joystick calibration

[jgraber]

After using Vexnet Upgrade Utility V4.1.2 and Cortex_V4_22.bin, I find that vexnet 1.0 (black) usb keys will do the joystick calibration (button 6up + config) as normal, but the new Vexnet 2.0 (white) usb keys do not.

Has anyone else noticed this, or have a workaround for Vexnet 2.0?

Hello jgraber,

Thanks for taking the time to visit our forum.
Yes, the calibration procedure changed with the VEXnet Keys 2.0
Basically the user no longer needs to tether in order to calibrate. Attached is the new revision of the instructions.

Let me know if you require further assistance.
Regards.

Vex staff pointed me to updated documentation on page 9 of this document:
http://www.vexrobotics.com/276-2192.html Quoted below:

I suggested they search for “joystick calibration” on vex.com and update every place that shows up.



6. VEXnet Joystick Calibration Procedure:
   a. When using (old black 1.0) vexnet keys, the Joystick must be linked to the microcontroller using the Keys.
   b. WHen using (new white 2.0) vexnet keys, the Microcontroller must be turned off.

c. Hold the “6U” Back Switch depressed.
d. While the “6U” Back Switch is depressed, use a small Allen Wrench (1/16” or smaller) or similar small straight tool
to depress and hold the CONFIG Switch.
Hold both Switches depressed until you see the Joystick LED Flash red and green – you can now release both
Switches.
aThere is a 10 second time limit to complete the following steps 5 and 6.
e. Move both Analog Joysticks to the maximum position desired in all 4 directions – Up, Back, Left, and Right.
– If a movement is not detected in all 4 directions, a timeout will occur after about 10 seconds and the
Calibration Mode will be discontinued and the VEXnet LED will briefly flash red.
– The Joystick LED will continue to flash red and green during the calibration process.
f. After movement is detected in all 4 directions, the Joystick LED will be ON and solid green.
aTo save the calibration, depress and release the “8U” top button.
If the calibration is accepted and saved, the Joystick LED will start flashing fast green for a few seconds.
aIf the calibration is not saved, a timeout will occur after about 10 seconds and the Calibration Mode will be
discontinued and the VEXnet LED will briefly flash red.
aTo cancel the calibration, depress and release the “7U” top button. The Calibration Mode will be discontinued
and the VEXnet LED will briefly flash red.
aIf the Calibration Mode is discontinued or saved, the Joystick LEDs will resume their normal function after the
VEXnet LED briefly flashes.

f. If Joystick Master Firmware is downloaded into the Joystick, the Joystick will need to be recalibrated.
