Unresponsive mbed
I've used mbed before, and thought I understood it. I've just pulled out an old LPC1768 mbed because I want to produce some timed digital pulses on a test jig.
I was a bit disconcerted when, upon opening mbed.org, I was presented with
"Sorry, we don't support new signups using this board. Please contact Support for more information. If you already have an accoumt, you should still be able to log in."
However, ignoring this and logging into my account, I started off with the Hello World Blinky code. I copy the compiled code to the module, the power led blinks in response, but upon reset I get no led activity. I've added the other 3 leds, no joy. The unit appears normally as a flash drive, the power led blinks upon download and reboot, but Blinky doesn't work.
Help!

Are you sure it is an LPC1768? Since they are still sold it is weird it would tell you no new signups are supported for the board. Could it be that it isnt an LPC1768, but an LPC2368? They were more like the prototype run, and they aren't sold anymore for a long time. And while similar to the LPC1768, it makes sense the binary is not directly compatible.
So try to read the IC, which one it is. If it is the LPC2368, besides contacting support, you can also try this link: https://mbed.org/platforms/mbed-LPC2368/. Luckily their platform links make sense, so just by changing the name I got there. I assume the add to compiler button there works fine (I won't try it out myself, since the remove from compiler button is still somewhere on their todo list :P).
