Hi t.man,
I've made a new board design using all parts contained in your schematic + an ISP connector.
The +5V connection at Y2 is not quite clear. Is it connected to pin15? Labels are normally placed left or on top of a pin. This one is underneath the pin meaning a dead short since it also is connected to ground. Also the ground connections to Y2 are not clearly recognizable. As I understood (also due to a missing junction) pins12 through 14 are connected to ground.
What frequency does the XTAL have and what kind of diode is used for D1? For the voltage regulator I assumed an 7805, also no value printed in the schematic.
Boncuk
D1 = 1N4007
XTAL= 4MHz
voltage reg= 78L05
sorry for Y2,
actually i was connecting it to suit my needs, i.e for the LC-display....
LCD pins arrangement: 14-13-12-11-10-9-8-7-6-5-4-3-2-1-16-15
with pin 1 as GND and pin 2 as voltage supply and pin 3 contrast adjust.
file attached.
