Thanks Hexley for the suggestions, here's what I've found:
I should have been a little more specific on the "each pin is 2.18V", I did mean just the numbered pins (i.e. p5 - p30). I took these voltages when being powered via USB, and the nR is showing about 3.19V, which seems close enough when considering the cheap multimeter. The Vout and Vusb are both working okay too at 3.3 and 4.8V respectively.
Sadly, I was also taking these measurements with this 1768 just sitting in an empty breadboard, so there's really no other hardware that could be compromising the values I measured.
From reading some other entries in the forum, it sounds like the problem may be in flashing the bin file. I'm able to transfer the bin files to the mbed, but when I press reset after the transfer, the Status LED fails to blink, which might suggest a problem loading the "XXXXXX.bin". I have since tried reformatting it, updating firmware, but no luck. It also may be worth noting that some times during file transfer, Windows explorer would freeze and terminate the transfer, which may have corrupted the bin files. I'm not sure how this would affect the board itself, though.
Thanks again for the help!
Hey everyone,
I've been using the LPC1768 as a prototyping board for our IEEE micromouse project, and as of yesterday I can't get it to respond to anything. I'm not a seasoned electrical engineer, so I'll try to describe the symptoms to the best of my ability:
-It was running a variety of programs just fine earlier: controlling steppers, sensors, etc. But as of yesterday I can't even seem to get a basic Blinky program running (the LEDs seem unresponsive). I can check the contents of the memory when plugged in via USB, and all the .bin files have transferred successfully, but after pressing reset, nothing happens.
-When I took my multimeter and checked voltage on each pin, they all seem to be at 2.18V, regardless of what any code specified.
I'm very confused, and if anyone's able to help, I appreciate it,
S
