Easy C Locking up

Easy C was doing great. Shut my computer down, then rebooted it b/c I need to load another program… Now when I send the program to the robot it keeps locking up and saying not responding… Any idea?

Try downloading through the USB A-A cable.
Does this happen only when easyc is open and you try downloading code with the robot plugged in?
If so, try reinstalling the drivers for it.

Where do I go to reinstall the drivers? Yes only happening when it is hooked up… It is like the whole computer is crashing… Hasn’t done this before.

First, just try unplugging everything and turning everything off, then plug everything in again and turn everything back on.

If that doesn’t work:

Plug in your usb thing (cortex with USB A-A Cable or joystick with USB Serial Cable)
Click Start, Run
Type devmgmt.msc
Hit Enter
Find the Cortex or the USB Serial Driver (may be under Ports)
Right click that entry
Click Uninstall
Unplug your USB thing
In Windows Explorer, Go to C:\Program Files\Intelitek\easyC V4 for Cortex#Tools\Drivers\ProlificUsbDriverAllInOne and run PL2303_Prolific_GPS_AllInOne_1013.exe
Also in windows explorer, go to D:\Program Files\Intelitek\easyC V4 for Cortex#Tools\Drivers\VEX Programming Driver and run VEX Programming Driver Installer 32-bit.exe (or the 64-bit version if there is one, and you’re on a 64 bit computer)
Plug your USB thing back in
Try downloading your code again!

Some other questions:
What is your operating system (Windows XP/Vista/7?)
What version of EasyC are you using?
To download your code, are you guys using the Orange Serial → USB cable that plugs into your joystick or the Orange USB A-A cable that plugs directly into the cortex?
What was the biggest “change” that happened to the computer or cortex right before it started freezing?

If Simmons 2.0 suggestions don’t help, it might be time for newer Drivers… It has been my experience over the last 10 year that Micro-Soft likes to “break things”, and the USB-to-Serial drivers are common victims… Including the Blue Screen of Death, and more “subtle” issues…

The Absolute Latest PL-2303 drivers from Prolific are these, PL2303_Prolific_DriverInstaller_v1.5.0.zip. Which consistes of v2.1.27.185 for Win 2K, XP, and Server 2003 and v3.4.25.218 for Windows Vista/7/Server2008/Server2008R2 (32 & 64-bit).

Indeed, I don’t understand why the VEX wiki still has drivers dated Dec 2006 on the wiki, I almost never use the RobotC/EasyC included drivers either unless I’m being lazy with a temporary installation (although I have to admit I’ve never had any problems with them).

Now wonder if it is my computer. My whole computer is slowing down.

You might look at your Hard Disk Drive… If your Hard Drive is experiencing Issues, the NTFS File System seems to Struggle Along, but with Slowness… Does your System Support S.M.A.R.T.?
