Next, send the PFC write address 0xa2and set the write pointer to the seconds register 2. Want to request a part post?

Parts: I2C real-time clock calendar (PCF) | Hackaday

We used our Bus Pirate universal serial interface to demonstrate this chip, but the transaction sequence will be the same for any microcontroller implementation. Fill in your details below or click an icon to log in: You are commenting using your WordPress. Sometimes the chip appears to return datasueet results.

The main Bus 8653t page has a bunch of examples of all the protocols: You can find this in the datasheet, or use the Bus Pirate search macro 1 to check all possible addresses.

First, a partial write transaction sets the memory location to read. This displays the values in the more familiar decimal format. This site uses Akismet to reduce spam. Leave a Reply Cancel reply Enter your comment here The output shows that a minute has passed since we set the time.

Finally, read 7 bytes r: We set the time to This seems to be a better way to read and write to test to see if a circuit works than even a arduino… The ads has some hard spi data sheets… it times out and sleeps I wonder how this would be if the chip has thowse sort of issues?

The values are entered in binary coded decimal format, with all numerical date representations being fairly standard see datasheet pages You are commenting using your Facebook account.

I managed to interface that with an Arduino with practically no idea what I was doing. The power supply can be 1.

The schematic above shows a bare-bones circuit for the PCF The datasheet also recommends a diode on the voltage input. Learn how your comment data is catasheet. The oscillator input pin needs an external capacitor C1, 12pFbut the oscillator output pin already has an internal capacitor.

For basic things it looks useful but without a example for the protocol that is needed in the documentation how would someone guess? The upper 7 bytes configure an alarm, timers, and other advanced features. It requires a simple external oscillator circuit with a Set the time by writing to registers 0x02 to 0x Second, use the read address 0xa3 to read bytes starting at the position set during the write command. Read values from the chip in two steps. Finally, write 7 bytes of data to the time registers at addresses Notify me ddatasheet new posts via email.

Retrieving the time takes two steps. Bytesshown in the table above, contain status and time information.

Please leave your suggestions in the comments. Write values by sending the I2C write address 0xa2the address to start writingand the data bytes s to write. Day of week reads 33, or 0b in binary.
