Board test (4 replies)

Hi,

I have done a silly thing, I could not get the mech end stops to trigger on my ramps1.4, so after trying everything else I swapped the ground/ positive to the negative on the end stops on ramps (Yes I know about the law of nature : "The dumb will suffer", I was dumb, I suffer. It was like 2am and I had been at it all day). There was a tiny little click and some smoke came out of the Atmega2560. My question is this, how do I figure out if all the components are fried, or only some of them, or all of them are still working?


After smacking my self a few times, and getting some sleep, I pulled the ramps of the atmega board, and plugged that into the usb serial connection of my pc. The LEDs on the 2560 are on. One steady amber, another higher up steady green and another, next to the steady amber is flashing around 3 time per second. It seems to connect and it seems to be taking gcode. Is the some sort of test script I can run on the board to see it it is functional? And if it is, how do I test the rest of it?

The ramps board's fuses seem ok
