Hi
My AXE033 with DS1307 fitted always worked fine.
I left it unused for a year or so and just tried connecting it up again.
As soon as I connected the 5v and 0v the top row of the display showed
16 black boxes and the Led that normally pulses once a second was off.
I read through the data sheet where it said I need to program in the time
to see the led flash. I programmed it in and sure enough it now flashes every
second. The fact that it programmed the time ok sugests to me that I must
have connected the in/out lines between picaxe and clock correctly, yet
nothing I try is making any characters appear on the lcd I just get the same
row of 16 black boxes on the top line and nothing on the second line.
So, is it dead or am I doing something silly?
