Has 38 inch reach with a dual bobcat type linear slides. Also a known bug.īuilt a prototype High hanging robot that tries to do it all. ROBOTC has no autosave after compile even if checked. Have yet to figure out the game joystick driversįixed the Joystick problem. The game joysticks did not work, except for channel 3. With the 75mhz legacy controller, got the expected results. I updated the firmware again per instructions and tried the operator controller. I now could download programs ok and not sure what cured the problem. The high pitched whine was about two octaves above middle C so I’m guessing about 1 khz hbridge pwm frequency unless it was a harmonic. The deadzone appeared to be +_8 pwm units when driven with a two wire port and around +_10 pwm units when driven from a regular motor port with the motor adapter. The motor seemed to run uneven and the max speed was noticibly slower going in reverse than forward. I hooked a two wire motor up and enabled the OnLineWindow and finally got it to work. I reinstalled the Prolific drivers from the Vex website (should be the same) and updated the firmware from the Easy C 4 START menu ( “C:\Documents and Settings\All Users\Application Data\Intelitek\IFI VEXnet Firmware Upgrade\usbhidio.exe) per instructions for both to the controller and the Vex game pad using the tether USB connected to the PC. I decided to get the Cortex running using the Eas圜 4 Cortex trial CD that came with the cortex. “ Bootload failed: Controller failed to respond to autobaud sequence“, repeatedly. Tried to download firmware and ran into this message:
#ROBOTC FOR VEX CORTEX SERIAL#
Installed the prolific serial driver from the RobotC web site. Downloaded the beta version ROBOTC 2.16 and followed instructions using the tether mode. Decided to use RobotC for initial installation and setup.
