Instructions for Using FEP16DTA

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the specified range of 2.7V to 5.5V.
   • Connect VSS (GND) to the system ground.

2. Communication Interface:

   • Choose either SPI or I2C for communication.
   • For SPI:
     • Connect SCK (Serial Clock), MOSI (Master Out Slave In), MISO (Master In Slave Out), and CS (Chip Select) pins to the corresponding pins on your microcontroller.
   • For I2C:
     • Connect SCL (Serial Clock) and SDA (Serial Data) pins to the corresponding pins on your microcontroller.
     • Ensure pull-up resistors are connected to both SCL and SDA lines.

3. Initialization:

   • Power up the device and initialize the communication interface.
   • Send the appropriate commands to set the initial wiper position.

4. Setting Wiper Position:

   • Use the Write Wiper command to set the wiper position.
   • The wiper position can be set from 0 to 255 (8-bit resolution).

5. Reading Wiper Position:

   • Use the Read Wiper command to read the current wiper position.

6. Non-Volatile Memory:

   • To store the wiper position in non-volatile memory, use the Store Wiper command.
   • This ensures the wiper position is retained even when the power is off.

7. Reset:

   • To reset the device to its default state, use the Reset command.
   • This will set the wiper position to 0 and clear any stored values in non-volatile memory.

8. Power Down:

   • When not in use, place the device in a low-power mode by setting the appropriate command.
   • This reduces power consumption to the quiescent level.

9. Handling and Storage:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the device.

10. Troubleshooting:

    • If the device does not respond, check the power supply and communication connections.
    • Ensure the correct commands are being sent and the device is properly initialized.
