Function:
Returns:
Address – Selects the zero-based address of the location in the EEPROM for
writing.
Data – Data to be written to the EEPROM.
Undefined.
This function will write the selected location in the EEPROM.
0x3, 0xAA, 0x2, 0xFE, 0x55 – Writes a value of 0xFE to EEPROM Address 2.
Port Pin – Selects the microcontroller port pin on the SX48 to be used for
communication with the DS18S20 temperature sensor.
1 Byte: A single byte indicating the result of trying to reset the temperature
sensor.
Sensor status definitions:
This function will select a port pin for communicating with a DS18S20
temperature sensor and start a temperature conversion. In addition to power and
ground connections, a 1.5K to 4.7K pull-up resistor must be connected between
VCC and the data pin of the DS18S20 for proper communication. The
conversion time for the DS18S20 is specified for a maximum of 750 milliseconds.
0x2, 0xAC, 0xB0, 0x1E – Starts a temperature conversion on SX48 port pin B0.
Port Pin – Selects the microcontroller port pin on the SX48 to be used for
communication with the DS18S20 temperature sensor.
9 Bytes: The contents of the scratchpad memory in the DS18S20.
This function will select a port pin for communicating with a DS18S20
temperature sensor and request the current contents of the DS18S20’s
scratchpad memory. A conversion (command 0xAC) must have been previously
requested for the data to be current. Additionally, host software must wait at
8
99: Sensor ready
8: Short circuit detected
2: No sensor detected
