Check the latest how-to, as well: The datasheet also daatsheet a diode on the voltage input. Leave a Reply Cancel reply Enter your comment here For basic things it looks useful ratasheet without a example for the protocol that is needed in the documentation how would someone guess? Check out the parts posts you may have missed.

Finally, read 7 bytes r: The main Bus Pirate page has a bunch of examples of all the protocols: Read values from the chip in two steps. Want to request a part post?

Email required Address never made public. Finally, write 7 bytes of data to the time registers at addresses The output shows that a minute has passed since we set the time. The power supply can be ddatasheet. This displays the values in the more familiar decimal format.

First, a partial write transaction sets the memory location to read. Sometimes the chip appears to return garbage results. You can find this in the eatasheet, or use the Bus Pirate search macro 1 to check all possible addresses.
