The EmbededLocoNet Library provides functions that manage the sending and receiving of LocoNet packets.
As bytes are received from the LocoNet by an interrupt driven handler, they are stored in a circular buffer and after a valid packet has been received it can be read out.
When packets are sent successfully, they are also appended to the Receive circular buffer so they can be handled in the same manner as if they had been received from another device.
Statistics are maintained for both the transmission and reception of packets. Any invalid packets that are received are discarded and the stats are updated approproately.
This library uses TIMER1 & ICP (UNO) and/or TIMER5 and ICP5 (MEGA) resources and associated interrupt handler hooks.
Currently the library only supports the AVR mega and tiny range that have an Input Capture Unit (ICP) associated with a 16-Bit Timer/Counter.
It's known to work with:
- UNO (ATmega328)
- MEGA (ATmega2560)
- Leonardo, LeoStick, Arduino Pro Micro (ATmega32U4)
- Various AVRTiny Boards (ATTiny84, ATTiny84A, ATTiny841)
