canpiwi's Introduction

CANPiWi

Welcome to CANPiWi project.

The MERG-CANPiWi is an application that designed to run on a raspberry pi attached to a CAN module transceiver. The app interfaces the MERG-CANBUS protocol and the JMRI Engine Drive application. It allows the user to drive model rail locomotives using the Engine Drive without the JMRI. The app also works as a CAN to CANGrid format via a tcp connection.

Building the project

Clone the project. If developing in a PC with copy the file /lib/liblog4cpp.a.pc to /lib/liblog4cpp.a If developing in a Raspberry pi with copy the file /lib/liblog4cpp.a.pi to /lib/liblog4cpp.a

Type make all.

Use the script initial_setup.sh to setup the raspberry pi in AP mode and compile the project.

canpiwi's Issues

Reduce Compiler Warnings

tcpClientGridConnect.cpp - attached is a git log -p output for the minor changes I made to reduce the number of compiler warnings from gcc 7.3
a) in canMessage : increase size of string buffer t to 3
b) in Constructor : Initialise msg_processed, msg_received, and running to zero. This still leaves queueReader uninitialised but since that variable is an opaque type there is no solution.

Make failure - link error

I was getting a linker error in the final compilation stage:

main.o: In function `main':
/home/pi/openbackup/CANPiWi/main.cpp:117: undefined reference to `log4cpp::OstreamAppender::OstreamAppender(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::ostream*)'

collect2: error: ld returned 1 exit status

Platform is a brand new Pi Zero W running Stretch:

Linux raspberrypi 4.9.41+ #1023 Tue Aug 8 15:47:12 BST 2017 armv6l GNU/Linux

I had to rebuild log4cpp.a from the source archive provided, after which make completed successfully.

./lib directory now contains:

Maybe ARM6 v ARM7 ? Or Linux version ?

If you have any questions, ask here or find me as 'sharp5' on the MERG forum.

Invalid zip

I've tried to download the zip file. The final size is 39KB and my windows 10 PC cannot open it as it is invalid. Can you help>

Turnout command fail

The turnout protocol from ED changed. Need to adjust the TURNOUT_REGEX to cope with the changes. It seems the MT is not being sent.
