eRPC (Embedded RPC) is an open source Remote Procedure Call (RPC) system for multichip embedded systems and heterogeneous multicore SoCs.
Unlike other modern RPC systems, such as the excellent [Apache Thrift](http://thrift.apache.org), eRPC distinguishes itself by being designed for tightly coupled systems, using plain C for remote functions, and having a small code size (<5kB). It is not intended for high performance distributed systems over a network.
eRPC does not force upon you any particular API style. It allows you to export existing C functions, without having to change their prototypes. (There are limits, of course.) And although the internal infrastructure is written in C++, most users will be able to use only the simple C setup APIs shown in the examples below.
A code generator tool called `erpcgen` is included. It accepts input IDL files, having an `.erpc` extension, that have definitions of your data types and remote interfaces, and generates the shim code that handles serialization and invocation. `erpcgen` can generate either C/C++ or Python code.
Example `.erpc` file:
```C++
// Define a data type.
enum LEDName { kRed, kGreen, kBlue }
// An interface is a logical grouping of functions.
interface IO {
// Simple function declaration with an empty reply.
set_led(LEDName whichLed, bool onOrOff) -> void
}
```
Client side usage:
```C
void example_client(void) {
erpc_transport_t transport;
erpc_mbf_t message_buffer_factory;
erpc_client_t client_manager;
/* Init eRPC client infrastructure */
transport = erpc_transport_cmsis_uart_init(Driver_USART0);
message_buffer_factory = erpc_mbf_dynamic_init();
client_manager = erpc_client_init(transport, message_buffer_factory);
/* init eRPC client IO service */
initIO_client(client_manager);
// Now we can call the remote function to turn on the green LED.
set_led(kGreen, true);
/* deinit objects */
deinitIO_client();
erpc_client_deinit(client_manager);
erpc_mbf_dynamic_deinit(message_buffer_factory);
erpc_transport_tcp_deinit(transport);
}
```
```C++
void example_client(void) {
erpc_transport_t transport;
erpc_mbf_t message_buffer_factory;
erpc_client_t client_manager;
/* Init eRPC client infrastructure */
transport = erpc_transport_cmsis_uart_init(Driver_USART0);
message_buffer_factory = erpc_mbf_dynamic_init();
client_manager = erpc_client_init(transport, message_buffer_factory);
/* scope for client service */
{
/* init eRPC client IO service */
IO_client client(client_manager);
// Now we can call the remote function to turn on the green LED.
client.set_led(kGreen, true);
}
/* deinit objects */
erpc_client_deinit(client_manager);
erpc_mbf_dynamic_deinit(message_buffer_factory);
erpc_transport_tcp_deinit(transport);
}
```
Server side usage:
```C
// Implement the remote function.
void set_led(LEDName whichLed, bool onOrOff) {
// implementation goes here
}
void example_server(void) {
erpc_transport_t transport;
erpc_mbf_t message_buffer_factory;
erpc_server_t server;
erpc_service_t service = create_IO_service();
/* Init eRPC server infrastructure */
transport = erpc_transport_cmsis_uart_init(Driver_USART0);
message_buffer_factory = erpc_mbf_dynamic_init();
server = erpc_server_init(transport, message_buffer_factory);
/* add custom service implementation to the server */
erpc_add_service_to_server(server, service);
// Run the server.
erpc_server_run();
/* deinit objects */
destroy_IO_service(service);
erpc_server_deinit(server);
erpc_mbf_dynamic_deinit(message_buffer_factory);
erpc_transport_tcp_deinit(transport);
}
```
```C++
// Implement the remote function.
class IO : public IO_interface
{
/* eRPC call definition */
void set_led(LEDName whichLed, bool onOrOff) override {
// implementation goes here
}
}
void example_server(void) {
erpc_transport_t transport;
erpc_mbf_t message_buffer_factory;
erpc_server_t server;
IO IOImpl;
IO_service io(&IOImpl);
/* Init eRPC server infrastructure */
transport = erpc_transport_cmsis_uart_init(Driver_USART0);
message_buffer_factory = erpc_mbf_dynamic_init();
server = erpc_server_init(transport, message_buffer_factory);
/* add custom service implementation to the server */
erpc_add_service_to_server(server, &io);
/* poll for requests */
erpc_status_t err = server.run();
/* deinit objects */
erpc_server_deinit(server);
erpc_mbf_dynamic_deinit(message_buffer_factory);
erpc_transport_tcp_deinit(transport);
}
```
A number of transports are supported, and new transport classes are easy to write.
Supported transports can be found in [erpc/erpc_c/transport](/erpc_c/transports) folder. E.g:
* CMSIS UART
* NXP Kinetis SPI and DSPI
* POSIX and Windows serial port
* TCP/IP (mostly for testing)
* [NXP RPMsg-Lite / RPMsg TTY](https://github.com/nxp-mcuxpresso/rpmsg-lite)
* SPIdev Linux
* USB CDC
* NXP Messaging Unit
eRPC is available with an unrestrictive BSD 3-clause license. See the [LICENSE file](https://github.com/EmbeddedRPC/erpc/blob/develop/LICENSE) for the full license text.
## Releases
[eRPC releases](https://github.com/EmbeddedRPC/erpc/releases)
### Edge releases
Edge releases can by found on [eRPC CircleCI](https://app.circleci.com/pipelines/github/EmbeddedRPC/erpc) webpage. Choose build of interest, then platform target and choose ARTIFACTS tab. Here you can find binary application from chosen build.
## Documentation
[Documentation](https://github.com/EmbeddedRPC/erpc/wiki) is in the `wiki` section.
[eRPC Infrastructure documentation](https://embeddedrpc.github.io/)
## Examples
[Example IDL](examples/README.md) is available in the [examples/](/examples/) folder.
Plenty of eRPC multicore and multiprocessor examples can be also found in NXP MCUXpressoSDK packages. Visit [https://mcuxpresso.nxp.com](https://mcuxpresso.nxp.com) to configure, build and download these packages.
To get the board list with multicore support (eRPC included) use filtering based on Middleware and search for 'multicore' string. Once the selected package with the multicore middleware is downloaded, see
<MCUXpressoSDK_install_dir>/boards/<board_name>/multicore_examples for eRPC multicore examples (RPMsg_Lite or Messaging Unit transports used) or
<MCUXpressoSDK_install_dir>/boards/<board_name>/multiprocessor_examples for eRPC multiprocessor examples (UART or SPI transports used).
eRPC examples use the 'erpc_' name prefix.
Another way of getting NXP MCUXpressoSDK eRPC multicore and multiprocessor examples is using the [mcux-sdk](https://github.com/nxp-mcuxpresso/mcux-sdk) Github repo. Follow the description how to use the West tool
to clone and update the mcuxsdk repo in [readme Overview section](https://github.com/nxp-mcuxpresso/mcux-sdk#overview). Once done the armgcc eRPC examples can be found in
mcuxsdk/examples/<board_name>/multicore_examples or in
mcuxsdk/examples/<board_name>/multiprocessor_examples folders.
You can use the evkmimxrt1170 as the board_name for instance. Similar to MCUXpressoSDK packages the eRPC examples use the 'erpc_' name prefix.

## Building and installing
These build instructions apply to host PCs and embedded Linux. For bare metal or RTOS embedded environments, you should copy the [erpc_c](/erpc_c) directory into your application sources.
**CMake and KConfig build**:
It builds a static library of the eRPC C/C++ infrastructure, the `erpcgen` executable, and optionally the unit tests and examples.
CMake is compatible with gcc and clang. On Windows local MingGW downloaded by [script](./install_dependencies.ps1) can be used.
**Make build**:
It builds a static library of the eRPC C/C++ infrastructure, the `erpcgen` executable, and optionally the unit tests.
The makefiles are compatible with gcc or clang on Linux, OS X, and Cygwin. A Windows build
of erpcgen using Visual Studio is also available in the [erpcgen/VisualStudio_v14](erpcgen/VisualStudio_v14) directory.
There is also an Xcode project file in the [erpcgen](/erpcgen) directory, which can be used to build erpcgen for OS X.
### Requirements
eRPC now support building **erpcgen**, **erpc_lib**, **tests** and **C examples** using CMake.
Requirements when using CMake:
* **CMake** (minimal version 3.20.0)
* Generator - **Make**, **Ninja**, ...
* **C/C++ compiler** - **GCC**, **CLANG**, ...
* **Binson** - https://www.gnu.org/software/bison/
* **Flex** - https://github.com/westes/flex/
Requirements when using Make:
* **Make**
* **C/C++ compiler** - **GCC**, **CLANG**, ...
* **Binson** - https://www.gnu.org/software/bison/
* **Flex** - https://github.com/westes/flex/
#### Windows
Related steps to build **erpcgen** using **Visual Studio** are described in [`erpcgen/VisualStudio_v14/readme_erpcgen.txt`](erpcgen/VisualStudio_v14/readme_erpcgen.txt).
To install MinGW, Bison, Flex locally on Windows:
```bash
./install_dependencies.ps1
* ```
#### Linux
```bash
./install_dependencies.sh
```
Mandatory for case, when build for different architecture is needed
* gcc-multilib, g++-multilib
#### Mac OS X
```bash
./install_dependencies.sh
```
### Building
#### CMake and KConfig
eRPC use CMake and KConfig to configurate and build eRPC related targets. KConfig can be edited by [prj.conf](./prj.conf) or _menuconfig_ when building.
Generate project, config and build. In [erpc/](./) execute:
```bash
cmake -B ./build # in erpc/build generate cmake project
cmake --build ./build --target menuconfig # Build menuconfig and configurate erpcgen, erpc_lib, tests and examples
cmake --build ./build # Build all selected target from prj.conf/menuconfig
```
**CMake will use the system's default compilers and generator
If you want to use Windows and locally installed MinGW, use [CMake preset](./CMakePresets.json) :
```bash
cmake --preset mingw64 # Generate project in ./build using mingw64's make and compilers
cmake --build ./build --target menuconfig # Build menuconfig and configurate erpcgen, erpc_lib, tests and examples
cmake --build ./build # Build all selected target from prj.conf/menuconfig
```
#### Make
To build the library and erpcgen, run from the repo root directory:
```sh
make
```
To install the library, erpcgen, and include files, run:
```sh
make install
```
You may need to sudo the `make install`.
By default this will install into `/usr/local`. If you want to install elsewhere, set the `PREFIX` environment variable. Example for installing into `/opt`:
```sh
make install PREFIX=/opt
```
List of top level Makefile targets:
* `erpc`: build the liberpc.a static library
* `erpcgen`: build the erpcgen tool
* `erpcsniffer`: build the sniffer tool
* `test`: build the unit tests under the [test](/test) directory
* `all`: build all of the above
* `install`: install liberpc.a, erpcgen, and include files
eRPC code is validated with respect to the C++ 11 standard.
### Installing for Python
To install the Python infrastructure for eRPC see instructions in the [erpc python readme](/erpc_python/readme.md).
## Known issues and limitations
* Static allocations controlled by the ERPC_ALLOCATION_POLICY config macro are not fully supported yet, i.e. not all erpc objects can be allocated statically now. It deals with the ongoing process and the full static allocations support will be added in the future.
## Code providing
Repository on Github contains two main branches: __main__ and __develop__. Code is developed on __develop__ branch. Release version is created via merging __develop__ branch into __main__ branch.

Introduction {#mainpage}
=================
eRPC (Embedded Remote Procedure Call) is an open source RPC system with a focus on constrained embedded environments.
Generally, RPC is a mechanism used to invoke a software routine on a remote system via a simple local function call. The remote system may be any CPU connected by an arbitrary communications channel: a server across a network, another CPU core in a multicore system, and so on. To the client, it is just like calling a function in a library built into the application. The only difference is any latency or unreliability introduced by the communications channel.
When a remote function is called by the client, the function's parameters and an identifier for the called routine are marshalled (or serialized) into a stream of bytes. This byte stream is transported to the server through a communications channel (IPC, TPC/IP, UART, etc). The server unmarshals the parameters, determines which function was invoked, and calls it. If the function returns a value, then it is marshalled and sent back to the client.
Here is a block diagram of an RPC system:
![rpc block diagram](./rpc_block_diagram.png)
This diagram only shows one direction of communication. It leaves out the reply from the server to send the invoked function's return value. This reply uses basically the same sequence of events, but flows back from the server to the client.
RPC implementations typically use combination of a tool (`erpcgen` in our case) and IDL (interface definition language) file to generate source code to handle the details of marshalling a function's parameters and building the data stream. The tool also generates code for a server side shim that knows how to unmarshal a request and call the appropriate function. The IDL input is used to tell the generator tool about data types and RPC services.

# About eRPC generator {#mainpage}
The eRPC generator (erpcgen) is a tool which generates the shim code for a server and client side. The generated shim code handles marshaling and unmarshaling a request. On the server side after unmarshaling, it implements a function call to the appropriate function based on request. An IDL (Interface Definition Language) is used to tell the generator tool about data types and RPC services.

# eRPC library code
Directory Structure:
- **config** - Holds the user-editable erpc_config.h header. This file can either be edited in place,
or copied to application code.
- **infra** - Contains C++ infrastructure code used to build server and client applications. For most
use cases, the APIs in the setup/ folder are easier. Accessing the C++ layer directly is only
required if you need to extend eRPC, or for atypical configurations.
- **port** - Contains the eRPC porting layer to adapt to different environments.
- **setup** - Contains a set of plain C APIs that wrap the C++ infrastructure, providing client and server
init and deinit routines that greatly simplify eRPC usage in C-based projects. No knowledge of
C++ is required to use these APIs.
- **transports** - Contains transport classes for the different methods of communication supported by
eRPC. Some transports are applicable only to host PCs, while others are applicable only to
embedded or multicore systems. Most transports have a corresponding C transport setup
function in the setup/ folder.
