General Input/Output services for Embedded Systems

EmbeddedIOServices

This is a unit tested hardware abstraction for embedded systems. The timer service has a built in scheduling system that can be used to trigger callbacks at precise times. Testing with 32 callbacks being scheduled on a STM32F103, sub microsecond accuracy was observed.

Interfaces that need to be implemented when adding new hardware abstraction

• IAnalogService
• InitPin(uint16 pin)
• ReadPin(uint16 pin)
• IDigitalService
• InitPin(uint16 pin, PinDirection direction)
• ReadPin(uint16 pin)
• WritePin(uint16 pin, bool value)
• ScheduleRecurringInterrupt(uint16 pin, CallBack callBack)
• ScheduleNextInterrupt(uint16 pin, CallBack callBack)
• IPwmService
• InitPin(uint16 pin, PinDirection direction, uint16 minFrequency)
• ReadPin(uint16 pin)
• WritePin(uint16 pin, PwmValue value)
• ITimerService
• GetTick()
• GetTicksPerSecond()
• ScheduleCallBack(tick_t tick) <= this is to call ReturnCallBack() at that tick
• ICommunicationService (UART, CAN, TCP, etc.)
• Call Receive(void* data, size_t length) when data received
• Send(void* data, size_t length)

Currently Supported Microcontroller

• STM32F103Cx
• STM32F401CC
• Full Stm32 Line, just add Stm32HalConf.h
• W806 and W801
