I have an older Vex kit that I dug up from the basement. The controller (“brain”?) looks like this: [image] I Installed VexCode and connected it to my laptop, but it didn’t appear to pick up the controller. Do I need to use an older software on my laptop to connect with this controller? (If so, a…

I’m not having much luck with RobotC so far. I see you can set the target to VEX Cortex 2.0. But I’m not even sure what model mine is… Version 1 perhaps? Might have to try an older version… Wonder if I have to update any firmware as well… (Not even sure that’s possible any more?)

You’ll need the really old ROBOTC, the 4.0 one may not support these. @Sylvie might be able to help, I think he programs some old PIC based VEX stuff.

I’m not finding a name for the controller. The docs I have just says “Vex Micro Controller Module”. And… it had a whining noise when its turned on and controlled via the remote control. Silent when I disconnect the remote control though… :thinking:

It’s a PIC v.5 VEX microcontroller. https://www.robotc.net/ Scroll down the page - I think you need version 3.63

This is a PIC Microcontroller (v0.5). @Foster would know where to find the correct version of robotC

@calvc01 was on it, The version is marked for the 0.5 system.

You’re right, I didn’t see that.

That you all very much. I’ll try the 3.63 version tomorrow. “0.5” - is in version number? It’s so old it’s “beta” version number?

Yes, it’s very old. [image] VEX Microcontrollers Through History General Forum VEX has had essentially five main families of robot control systems, listed here by their main Brain: Consumer / retail products (VEXplorer, HEXBUG VEX Robotics) VEXplorer (2007) HEXBUG VEX…

I’ve downloaded v3.63. But I’m not sure how I can verify it’s working. Nothing comes up automatically when I plug in the PIC via the USB-serial cable. Also, is there a way to fetch the program currently on the PIC? And a way to check the firmware of the PIC?

Using an older microcontroller?
