Bus Pirate Support / Bus Pirate n DS1307
Hi,

I'm using the bus pirate v3.5 to read the DS1307 using the I2C protokoll. Everything look fine, but everything couple of time of reading the DS1307 provide rubbish readings. the weird part is a it only happens when reading the DS1307 every 1-2 second gap. The first good reading, rubbish, good...etc.

has anyone counter this? defekt from the DS1307 chip?
