RTC:99:5: error: expected ‘}’ at end of input

expected ‘}’ at end of input

Is what I am getting when I try to verify and compile. it is showing up for the very last } at line 99.

also when i try to use the RTC code it asks about the rtclib and that there is no directory.

I copied the digitizer code (only changed the pins), and have it running. The behavior is not what I expect though, “Mode 1” lights up all the colored LEDs, but none of the digits; “Mode 2” – 4 light all the segments in each digit for all the digits, but none of the LEDs. It looks like it doesn’t matter what I put in my bit, if I put B1xxxxxxx, it turns all the LEDs on, and B0xxxxxxx turns all the segments of all the digits on.

I realized initially I had one of the shift registers in backward (I thought both were supposed to be pointing to the center of the board), and the backward one got very hot. Do you think this burnt out, and that is why I’m seeing this behavior?

Sorry to double post, I don’t see an edit button. I found an extra shift register of the same type and tried putting it in, but I’m getting the same behavior.

I’ve tried to post this 3 or 4 times now, I’m not seeing it though, so I’ll try once or twice more:

I did a visual inspection, didn’t find any solder bridges. Then I tried with my multimeter, still didn’t find anything awry. Sorry if this double posts, after I hit submit the post just seemed to disappear, and isn’t showing up even after I refresh.
