- auxiliary_controller: BoostC Project in C with the firmware for the PIC16F886. Implemented Interrupts Timer1 (RTC), SPI, ADC (Battery Voltage). The python SPI API for this MCU is in
components/auxiliary_controller.py - components: Devices interfaces. At the moment it describes SPI interfaces, mostly used from the master side.
- openmv_thermal: Files to be places at the root of the file system of the OPENMV master (with the Letpon module)
- helpers: Utility functions or clases that depend on object instances from the main.py
- openmv_visual: Files to be places at the root of the file system of the OPENMV master (with the Letpon module)
- utils: Utility functions or clases that are independent and can be re-used.
Master OPENMV (openmv_thermal) python class instances
The master OPENMV implements in python the following class instances:
- auxiliary_controller: Fetches all the data from the PIC16F886. Battery voltage, Real time clock counter, button press info.
- touch. Interface with XPT2046. It handles the calibration of the touch screen.
- control. Stores most of the camera variables and manages the images from SD
- thermal. Interface the Lepton 3.5
- menu: Contains a dictionary with all the information about the menus to be displayed when each key is pressed
- screen: Interface with ILI9341
- settings: User settings
- time_settings: It stores the datetime and the RTC count at the time of the time-set. This allows the OPENMV to know the absolute time when it boots. Additionally there is a calibration factor which can be used to get higher accuracy.
- input_handler: Pipes the interrupt through the appropiate callbacks, so the final callback has all the class instances required and
- camera_slave: Buffers and manages the data transfer of the visual camera image via SPI
- logger: Temporary placeholder with an info method. TODO to set a proper logger
