Im trying to interface nRF52DK to Custome build acceleration sensor.
I want to use I2C communication. Are the pin connections mentioned below sufficient?
LIS3DH | nRF52DK | other | Reason | |
CS | 3.3V | Pulled high for I2C | ||
SCL | P027 | 4.7kohm resistor to 3.3V | Pulled high for I2C | |
SDA | P026 | 4.7kohm resistor to 3.3V | Pulled high for I2C | |
SDO | ??????? | |||
Should SDO pin be connected to something? and what is its exact purpose? i did read the LIS3DH document. But still a bit unclear.
