PIC firmware for CANMIO with configurable IO. Uses the CBUSlib https://github.com/MERG-DEV/CBUSlib.

Currently work in progress. ToDos and DONEs: TODOs

• Bootloader and handling of OPC_BOOT
• Flicker LED on CAN activity can18.c
• Work out what to do if all CANIDs are taken can18.c
• Check handling of REQEV events.c
• More validation of NV values
• Implement ENUM
• Implement NENRD
• Implement CANID
• Consider option to set outputs on or off on powerup in addition to restore previous state
• Heartbeat message
• Fix INVERTED for all types
• Randomise bounce
• RFID input
• Analogue inputs for magnetic and current sense detectors

DONES:

• DONE Check handling of REVAL events.c
• DONE Implement NNRST
• DONE Implement NNRSM
• DONE needsStarting in Pulse OUTPUT
• DONE Change order of Pin Configs 0-7 done. 8-15 need checking
• DONE Implement AREQ but doesn't handle default events
• DONE Fix saved events when doing SNN - not needed
• DONE Flash OUTPUT type
• DONE Extend ActionQueue size
• DONE Determine how to send lots of CBUS messages without filling TX buffers
• DONE Consider a delay action for sequences
• DONE Check handling of NERD is correct and produces correct ENRSP events.c
• DONE change the START_SOD_EVENT for a learned action/event
• DONE consumed event processing
• DONE validate NV changes
• DONE servo outputs
• DONE debounce inputs
• DONE invert inputs
• DONE invert outputs
• DONE multi-position outputs
• DONE Fix deleteAction events.c
• DONE Pulse outputs
• DONE Bounce algorithm for servos
• DONE Store output state in EEPROM + restore on powerup
• DONE add a max loop count for bounce calculations
• DONE Change doAction to properly check for global actions
• DONE Move SOD processing to doAction from processEvent
• DONE Fix the SOD processing to include mid events
• DONE remember output state in EEPROM outputs.c & servo.c
• DONE Need more config changes when changing type
• DONE NV change callback for type change
• DONE add needsStarting and completed for OUTPUT types so can be processed sequentially
• DONE sequence servos servo.c

Please check that you are using the C18Ian branch from git.

The other important thing to know is the project setup in MPLAB. I create a separate MPLAB project within the usual MPLAB workspace and then import the files from the git directory. I create logical folders thus: CANMIOfirmware

• Header files
  • CANMIOfirmware
  • CBUSlib
• Source files
  • CANMIOfirmware
  • CBUSlib

In the project properties you need to put in the header file include paths under C18 Global Options -> mcc18 -> General -> Include directories = ../../githib/CANMIOfirmware; ../../github/CBUSlib

The actual CBUSlib files needed by the project are:

• callbacks.h
• can18.h
• cbus.h
• cbusconfig.h
• cbusdefs8n.h
• cbuslib.h
• devincs.h
• EEPROM.h
• events.h
• Flim.h
• romops.h
• StatusLeds.h
• TickTime.h
• can18.c
• cbus.c
• events.c
• Flim.c
• romops.c
• StatusLeds.c
• ticktime.c

You will also need to ensure you are using the correct linker script.

I found I had a bit of difficulty with uppercase/lowercase of filenames. In particular the Flim.[ch] were troublesome. Also if building on linux the C18 compiler needs the 18F26K80_e.lib copied to 18f26K80_e.lib for the library to be found correctly.
