A library designed to provide easy communication with a device sending data via the Innovate Serial Protocol version 2. This library is currently read-only.
The main project is the library, libISP2, which attempts to decode a stream that uses the Innovate Serial Protocol and provides a simple API to access any valid data within that stream.
There is an example project that shows basic usage with a file descriptor:
/libiSP2_example [-v] [-d] [-s] file
Where:
file- A file or device node. If a file, should be raw binary output from a supported Innovate device.-s-fileis a serial port (eg./dev/ttyS0,/dev/ttyUSB0). Sets up correct baud rate and whatnot to work.-d- Add a ~40ms delay to file input to simulate realtime. Don't use this with-s.-v- Not implemented
libISP2 provides the function ISP2::isp2_read. The first argument is a file descriptor, the second is an isp2_t struct. It will attempt to parse one packet from the given file descriptor into the given struct. If successful, ISP2::isp2_read will return 0. If ISP2::isp2_read cannot find a header, it will return -1.
Until I write more better documentation, please have a look at isp2.h for information about the isp2_t struct.
git clone https://github.com/nearwood/libISP2
cd libISP2
cmake --build build
make
#make install #TODO IncompleteBinaries would be then located in build/bin and build/lib.
- Fix serial port access
- Move serial port to library, as optional at compile time
- CLI example
- GUI gauge example
- Convert ISP2 library to C, not really using C++ features
- Export NO_SERIAL_SUPPORT to cmake
- Use non-blocking IO, and show some kind of RX indicator
- Add more emojis
- techie66 for the original implementation.
