CHAL_SHARED

Shared libraries for all our CHAL components

Module Definitions

Color Conversion Module

• Files can be found undercolor_conv.h/.cpp
• Module allows for easy conversion between HSV and RGB colors
• Also converts between the Kelvin white balance value and it's RGB counter part

IPC Impleemntation

• Files can be found under csal_ipc_message_publishqueue.cpp/h cal_ipc_message_subscribequeue.cpp/.h csal_ipc_thread.cpp/.h csal_ipc.h.h/.cpp
• IPC management layer to talk to other devices over serialized interfaces. Implements both callbacks and queues for handling events/data sent over the IPC
• Subcribequeue and publish queue are separate threads handling data.
• Relies on preconfigured enumerated messages

LED Matrix module

• Files can be found in csal_ledmatrix.cpp/.h
• Generic LED matrix handler.

LED Strip modules

• Files can be found in os_led_strip.cpp/.h
• Generic LED strip handler for all LED strip data

Hardaware Prototypes and declarations

All of our hardware modules that may or may not be implemented are wraped through modules defined inside here.

• SPI os_spi.h
  • Mostly function declarations, and maybe some platform generic calls for the SPI bus interface.
  • Setup such that you need to first initialize a SPI bus, then you can "add" hosts onto the bus, ergo setting up a chip select pin and connecting it to a selected SPI bus on whatever gpio pins(or whatever the platform supports)
• Bluetooth os_bt.h
  • Mostly function declarations, bluetooth endpoints and descripter information.
  • Helps send data, setup callbacks for received data from specific endpoints and descripters.
  • Non BLE interface information
• GPIO os_gpio.h
  • General purpose IO function declarations, and maybe some helper code that's platform agnostic.
• I2S os_i2s.h
  • Mostly function declarations, and maybe some platform generic calls for the I2C bus interface.
  • Sets up device on bus(based off chip select pin), send data to that device
• I2C os_i2c.h
  • Mostly function declarations, and maybe some platform generic calls for the I2C bus interface.
    • Basic interface, you can send out data to a specific address on the bus.
• UART os_uart.h
  • Mostly function declarations, and maybe some platform generic calls for the I2C bus interface.
    • Basic interface, you setup the gpios(if supported on the platform, otherwise it's whatever gpio they are set on) and send data, no device or address
• WiFi os_wifi.h
  • Mostly function declarations, and maybe some platform generic calls for the WiFi interface
  • Currently only designed for a singular WiFi interfaces, and no ethernet
  • Construct and deconstruct connectionst to WiFi interfaces
  • Hosting TCP and UDP socket servers, also supports TCP and UDP socket clients
• ADC os_adc.h
  • General purpose IO function declarations, and maybe some helper code that's platform agnostic.
