Hello, i'm trying to use the AXE033 board with the LCD display. I'm using i2c interface, but it doesn't seem to work.
I've followed the instruction: added both J1 and J2 jumpers, regulated contrast etc. I've tryed the sample code to show Hello but nothing
One thing is that when i connect power, the first line show all black (ie, all dots are black on all characters). The manual says it should show the time/date or 00/00/00 00:00 if not using a clock (my case). Can it be that my soldering has short circuited some pins ? any other idea ?
Many thanks
