Hello everyone.
I wanted to know what value of pull up resistors should I use for SMBus?
I am planning to use BQ3060 as slave and ATSAMA5D36( http://www.atmel.com/Images/Atmel-11121-32-bit-Cortex-A5-Microcontroller_SAMA5D3_Datasheet.pdfas master in SMBus. ATSAMA5D36 uses Three Two-wire Interface up to 400 Kbit/s supporting I2C Protocol and SMBUS.
I am really new to SMBus and wasn't sure if i made right calculations using this http://www.ti.com/lit/an/slva689/slva689.pdf .
I calculated that pull up resistor value should be between 0,96kΩ and 118 kΩ. (In ATSAMA5D36 it seems like I/O pin capacitance is 10pF).
Can anyone confirm my calculations or give some kind of advice?
