Constructor
Member Function Documentation
◆ begin()
| bool Adafruit_FRAM_I2C::begin | ( | uint8_t | addr = MB85RC_DEFAULT_ADDRESS, |
| TwoWire * | theWire = &Wire |
||
| ) |
Sets up the hardware and initializes I2C.
- Parameters
-
addr The I2C address to be used. theWire The Wire object to be used for I2C connections.
- Returns
- True if initialization was successful, otherwise false.
◆ getDeviceID()
| void Adafruit_FRAM_I2C::getDeviceID | ( | uint16_t * | manufacturerID, |
| uint16_t * | productID | ||
| ) |
Reads the Manufacturer ID and the Product ID frm the IC.
- Parameters
-
[out] manufacturerID The 12-bit manufacturer ID (Fujitsu = 0x00A) [out] productID The memory density (bytes 11..8) and proprietary Product ID fields (bytes 7..0). Should be 0x510 for the MB85RC256V.
