I thought the ATMEGA has internal pullups on the SDA/SCL i could be wrong? . like i said I dont even have the ATmega inserted on the setup and it would still over heat..
It does, and if the Wire library is being used, it will enable them. It will probably even work this way, but the pullups are technically too weak. External pullups between 2.2K and 4.7K would be best. But either way, this will not cause overheating.
Four posts in you tell us about the voltage regulator. Have you measured its output?
I do use the Wire library lol.. A software engineer cannot talk the I2C's,etc himself haha..
Yeah output it fine.. 5V exact.
Now I tried to just use the output from voltage regulator to the DS1307 VCC and GND and nothing else.. it doesnt heat up.
Im trying everything from scratch .
Jack, please look at the schematic, then tell me THIS WILL do the job.. I would wire all the things carefully on a larger solder board and try.
