You were typing the right thing, but when you're calling a module (at least for the first time after reset, unless you've saved it with the module), you need to type it into the RIGHT HAND SIDE of the WebIDE, and then click "Send to Espruino" in the middle.
If you put the exact same code in, but on the right side and click "send to Espruino" it will work.
When you type in left side, that goes directly to the Espruino.
When you type in right side, and then do send to Espruino, that gets processed by the WebIDE, which downloads the modules and sends them to the Espruino, along with your code.

=undefinedHow do i get rid of it then? And also when i hook the leds up the screen goes blank? What do i need to do?
-
Can you please describe what you are doing that causes that message to appear, including any code, and how you send that code to the espruino?
I assumed you were typing something like "require("Touchscreen").... " in the left side of the webIDE, but it sounds like that's not the case, in which case, please explain what you're doing that triggers that error.
Also, someone who has the HY STM32 board might be helpful here too - I have not used that one, so if there's something weird about how the HY STM32 boards specifically work, I don't knwo it.

this is what i get when i send require() in right and press send. I havent change anything in settings . under where it says url to find modules it has http://www.espruino.com/modules.

Now im getting this

Update firmware to v72 to fix the issue with setting watches (as well as OODLES of other bugs - v71 -> v72 is a major update).
I'm still not sure why you're getting the error about ADS7843 module not being found - The WebIDE should have noticed that it needs the ADS7843 module, and automatically fetched it and loaded it with the board - but it looks like it didn't do that. Did any error messages appear when you sent the code (they pop up in colored boxes near the lower right that only stay for a few seconds, so it's hard to see what they say, but that's where it displays errors about not being able to get modules).
-
The =undefined is normal and correct, but often surprising to someone coming to Espruino from an embedded background, vs a JS background. When using a JS console, everything you send gets evaluated. A blank line evaluates to undefined, so that gets echoed back to you.
If you have updated it, it should be showing different messages, I would think. Can you post the results of sending the same code with v72?

How many LEDs is that? You probably can't power very many off the builtin power source, and since they flash on when you connect them, that might be enough to reset the board. Does it work when you have the LEDs connected when you power it on? (in that case, I'd expect you to be able to turn on a few LEDs before overloading the power supply).
You'll need an external supply to power any decent number of those wonderful LEDs. On full white they pull 50-60mA a pop!
-
Out of interest, what did you change to get the code loaded on properly?
As @DrAzzy says, if the screen goes away when you hook up the LEDs then it could well be that they're drawing too much power, so you might need a separate power supply.
You could try hooking just one or two up to check it works - just having a few on should be fine running off USB.

When using JS module code, you need to enter the first require(...) for a given module (after each reset, assuming you haven't save()'ed after loading the module) on the right side of the window, that way the WebIDE knows to go get that module and send it to the Espruino.
If you send code using a module from the right side of the IDE, and then press up arrow a few times to see command history, you can see where it sends over the minified module code.
