Introduction

Tiny SLIP Protocol is layer 2 protocol. It is intended to be used for the systems with low resources. You don't need to think about data synchronization between points. The library use no dynamic allocation of memory. It is also can be compiled for desktop Linux system, and it can be built it for Windows. Using this library you can easy implement data transfer between 2 microcontrollers or between microcontroller and pc via UART, SPI, I2C or any other communication channels. Tiny SLIP protocol is based on RFC 1055. This protocol doesn't implement any error detection! If you need error detection and frames acknowledgment, please refer to TinyProto library.

Dependencies

• buildsys integrated to this library
• tinyhal as submodule

Key Features

Main features:

• Frames of maximum 32K or 2G size (limit depends on platform).
• Low SRAM consumption (starts at 50 bytes).
• Low Flash consumption (starts at 1KiB)
• No dynamic memory allocation
• Serial loopback tool for debug purposes and performance testing

Supported platforms

• Any platform, where C/C++ compiler is available (C99, C++11)

Easy to use

Tiny SLIP Library is very easy to use:

SLIP::SLIP  proto;

void onReceive(SLIP::IPacket &pkt)
{
    // Process incoming packets here

    /* Send message back */
    proto.write( pkt );
}

...
...
    proto.setReceiveCallback( onReceive );
    proto.begin();
...
...
    if (Serial.available()) {
        uint8_t byte = Serial.read();
        proto.run_rx(&byte, 1);
    }
    uint8_t byte;
    if ( proto.run_tx(&byte, 1) == 1)
    {
        Serial.write( byte );
    }

How to build

Linux

1. Getting source code

If you wish to build the library with all dependencies you need to clone project using command

git clone --recursive https://github.com/lexus2k/tinyslip

If you have all dependencies installed in the system, use the following command for cloning

git clone https://github.com/lexus2k/tinyslip

2. Building

make
# === OR ===
mkdir build
cd build
cmake -DEXAMPLES=ON ..
make

Windows

1. Getting source code

If you wish to build the library with all dependencies you need to clone project using command

git clone --recursive https://github.com/lexus2k/tinyslip

If you have all dependencies installed in the system, use the following command for cloning

git clone https://github.com/lexus2k/tinyslip

2. Building

mkdir build
cd build
cmake -G "Visual Studio 16 2019" -DEXAMPLES=ON ..

ESP32

1. Getting source code

TODO

2. Building

Just build your project as regular ESP32 IDF project.

Cross-compilation

1. Getting source code

If you wish to build the library with all dependencies you need to clone project using command

git clone --recursive https://github.com/lexus2k/tinyslip

If you have all dependencies installed in the system, use the following command for cloning

git clone https://github.com/lexus2k/tinyslip

2. Building

make CROSS_COMPILE=<prefix> STAGING_DIR=<your_staging_dir>
# === OR ===
mkdir build
cd build
cmake -DEXAMPLES=ON ..
make

Setting up

• Arduino Option 1 (with docs and tools)

  • Download source from https://github.com/lexus2k/tinyslip
  • Put the downloaded library content to Arduino/libraries/tinyslip folder
  • Restart the Arduino IDE
  • You will find the examples in the Arduino IDE under File->Examples->tinyslip

• Arduino Option 2 (only library without docs)

  • Go to Arduino Library manager
  • Find and install tinyslip library
  • Restart the Arduino IDE
  • You will find the examples in the Arduino IDE under File->Examples->tinyslip

• ESP32 IDF

  • Download sources from https://github.com/lexus2k/tinyslip and put to components folder of your project
  • Run make for your project

• Linux

  • Download sources from https://github.com/lexus2k/tinyslip
  • Run make command from tinyslip folder, and it will build library and tools for you

• Plain AVR

  • Download sources from https://github.com/lexus2k/tinyslip
  • Install avr gcc compilers
