Dependencies:   BLE_API X_NUCLEO_6180XA1 X_NUCLEO_IDB0XA1 X_NUCLEO_IHM01A1 X_NUCLEO_IKS01A1 mbed

Fork of SunTracker_BLE by ST Expansion SW Team

Overview

The SunTracker is a demo application running on ST Nucleo-F401RE stacking a set of ST X-NUCLEO expansion boards.
Main features provided are:

  • A solar panel follows the light source, orienting the panel in order to achieve the best panel efficiency.
  • Orientation is controlled thanks to a couple of VL6180X FlightSense light sensors mounted on a X-NUCLEO-6180XA1 expansion board and driven by X-NUCLEO-IHM01A1 controlled stepper motor acting as actuator to orientate the panel.
  • The system features a progressive control on the stepper motor in order to modulate the panel rotation speed according to the light angle.
  • The application is also able to control the panel productivity reading the panel voltage through an ADC and proving feedback on the local display.
  • A manual orientation is possible by using the accelerometer on a X-NUCLEO-IKS01A1 expansion board that, according on board tilt, controls the speed and the rotate direction.
  • A remote control is available using a X-NUCLEO-IDB04A1 or a X-NUCLEO-IDB05A1 Bluetooth Low Energy expansion board. Remote control software is here.

Working Status

  • SunTracker has 3 working status visible on FlightSense display and switchable by pressing the User Button:

Status 0 (Idle)

  • Motor: Free Turning
  • Display: Waiting for User Button

Status 1

  • Motor: Driven by Light
  • Display: Direction and Light Intensity = Direction and Motor Speed

Status 2

  • Motor: Driven by Light
  • Display: Solar Panel Efficiency

Status 3

  • Motor: Driven by Accelerometer
  • Display: Direction and Accelerometer Intensity

Server Startup

  • When you plug the power supply, the word ‘PUSH’ is shown on display.
  • You can manually rotate the structure to assign the ‘Zero Point’. Then press the User Button to launch the application.
  • The display will show this status, which means that the structure is oriented to maximize the efficiency of the solar panel.
  • If there is a light displacement, the structure will rotate, left or right, to follow the light source and on display is shown the direction and the speed.
  • You can press the User Button to show the panel efficiency with 4 digits that represent the range from 0v (0000) to 3,3v (3300).
  • Further pressing the User Button you will manual rotate the panel by tilt the Server or Client accelerometer depending by BLE connection.

Client Startup

  • The Client application can remotely control the User Button and the Accelerometer functions.
  • Power on the Client AFTER the Server, it will automatically search for the SunTracker and will establish a BLE connection.
  • The Green Led on Nucleo Client board will be powered on.

Rotation Features

  • It has been implemented a block of rotation to avoid cables twist.
  • The blocking point can be set in the firmware by changing a constant.
  • You can manually rotate the structure to assign the ‘Zero Point’ before press the User Button to launch the application.
  • The system features a progressive control on the stepper motor in order to modulate the rotation speed according to the light or accelerometer angle.

HARDWARE SETUP

Nucleo ADC + Solar Panel

Connect Solar Panel cables to Nucleo Morpho PC_3 (white) and Nucleo Morpho GND (black). Connect a capacitor 10uF between PC_3 and GND to stabilize its voltage value shown on display.

EasySpin (L6474) + BLE

Hardware conflict between EasySpin DIR1 and BLE Reset, both on same Arduino Pin PA_8. Disconnect PA_8 between EasySpin and Nucleo by fold EasySpin Pin. PB_2 has been configured as EasySpin DIR1 in the firmware . Connect Nucleo Morpho PB_2 to FlightSense Arduino PA_8 by a wire.

FlightSense Satellites

In case of instability with I2C due to long flat cables, solder 4 SMD capacitors 47pF on FlightSense board in parallel between R15, R16, R17, R18 and plug 2 capacitors 15pF between FlightSense Arduino PB_8 and PB_9 to GND pin to cut-off noises over 720 KHz.
