Can we interface smbus based sensor with NRF51/52 ?

Hi,

Can we interface a smbus based sensor with NRF51 or NRF52? The only difference between smbus and TWI is the minimum speed requirement which is 10Khz if I am correct.

Hi,

There are some more differences between the bus specifications, for instance does the SMBus specify a maximum frequency of 100 kHz.

Nomally it is no problem to interface SMBus devices using TWI, as long as you keep the speed at 100 kHz.

Best regards,

Jørgen
