- Expanded photodiode support from 6 to 13-21 photodiodes - Added configurable sampling rates (0.1-100 Hz) with runtime configuration - Implemented ADC multiplexing support for >16 photodiodes - Added new operation types: OPERATION_PHOTODIODE_CONFIG - Enhanced data structures with active_count and validation flags - Updated driver with multiplexed ADC reading functions - Added sample rate control and validation - Improved main loop with dynamic sampling rate adjustment - Enhanced command processing for configuration changes - Added comprehensive error handling and logging
…uthor - Remove multiplexed photodiode read function and related variables - Remove redundant ADC channel definitions (will be replaced by Atmel Start) - Change floating-point sample rate to integer delay time in ms - Add Avinash Patel as author in all photodiode files - Simplify driver interface and remove over-engineered logic
- Updated PHOTODIODE_MAX_COUNT from 21 to 22 - Added multiplexer control functions (init_multiplexer_gpio, set_multiplexer_channel, read_single_photodiode_adc) - Added multiplexer configuration structure with GPIO pin definitions - Implemented 5-bit multiplexer control for 22 channels (2^5 = 32 > 22) - Added multiplexer settling time handling (1ms) - Updated ADC reading to use multiplexer switching - Enhanced configuration to support multiplexer mode - Fixed syntax errors in task_list.h (missing newlines) - Added comprehensive error handling and validation This enables support for 22 photodiodes using a single ADC channel with a multiplexer, providing full sun sensing capability for ADCS.
- Add comprehensive camera task with full functionality (not skeleton code) - Implement camera_driver.h/c with SPI communication and hardware abstraction - Add camera_task.h/c with complete command interface and auto-exposure algorithm - Create camera_main.c with proper FreeRTOS task integration - Add camera operations to globals.h operation enum: * OPERATION_CAMERA_CAPTURE * OPERATION_CAMERA_CONFIG * OPERATION_CAMERA_STATUS * OPERATION_CAMERA_AUTO_EXPOSURE - Integrate camera task into task_list system with proper stack allocation - Fix photodiode compilation errors on this branch - Update Makefile to include camera task compilation Features implemented: - Clean 'take-picture' command interface - Configurable settings (exposure, brightness, contrast, quality) - Auto-exposure algorithm for varying orbital conditions - Multiple image formats (RGB565, RGB888, YUV422, JPEG, GRAYSCALE) - Proper memory management and error handling - Full integration with PVDXos task system Total: 1,670 lines of functional camera code across 5 files
- Create new file structure with clear separation of concerns - Implement consistent naming conventions throughout - Add hardware abstraction layer (camera_hw.h/c) - Centralize type definitions (camera_types.h) - Organize configuration constants (camera_config.h) - Create main public API (camera.h/c) - Update existing files to use new structure - Maintain backward compatibility with existing functionality New structure: - camera.h/c: Main public API - camera_types.h: All type definitions and enums - camera_hw.h/c: Hardware abstraction layer - camera_config.h: Configuration constants - camera_main.c: Task main function - camera_task.c/h: Task implementation All functions follow camera_* or camera_hw_* naming pattern
