I'm working with nrf51 board, I'm using I2C to communicate with an accelerometer (see the scheme), the communications are successful but I dont see any pull up resistors in the lines SDA
and SCL
.
could I2C work without pull-up resistors or is the scheme wrong or does the accelerometer has internal pull up on lines SDA and SCL
this answer is saying that the pull-ups are probably in the microcontroller, is this right?
