BlockWorks

Blocks is a set of small, finey crafted, composable blocks for embedded systems. It is intended that these blocks be picked and modified as appropriate. Broadly, the areas that are covered are:

• Abstractions and softwae implementations of bus drivers and commnications devices, i.e. I2C, SPI, UART, CAN.
• Common storage structures; Logging, KeyValueStore.
• State Machine and event dispatch mechanism; EventQueue, *Events.
• Test running and reporting mechanism.

Blocks

• Queue; Multipurpose, static queue.

• Hash Table.

• EventQueue; General purpose function call queue.

• BlockedEvents;

• PredicatedEvents;

• TimedEvents;

• Debugger;

• FileStorage;

• KeyValueStore;

• LogStorage; General purpose, append-only storage of fixed-size blocks.

• PersistentStorage; Abstraction of a FLASH-type storage system, fixed-size blocks.

• I2CMaster; I2C s/w master, uses two GPIO pins.

• UARTReceiver; UART s/w transmitter, uses a GPIO pin.

• UARTTransmitter; UART s/w receiver, uses a GPIO pin.

• SPI master;

• SPI receiver;

• CAN

• Platform;

• Utilities;

• Framebuffer;

• Font;

• TextDisplay;

• MODBUS RTU;

• MODBUS ASCII;

• HART;

• NMEA;

• PPP;

• GPIB;

• UnitTest;
