🦀 Rust wrapper for a famous BACnet Protocol Stack library in C

bacnet-stack-rs

This library is a Rust wrapper for the BACnet Stack project, built with bindgen, cmake, and love 💚.

The folder bacnet-sys/bacnet-stack contains the submodule of the original C library.

Also, this repository is kind of a fork of this other one, updated to the latest version of Rust and bacnet-stack.

Updating the stack

To update the stack, you need to update the submodule bacnet-stack to the latest commit, always check if cargo can still build the project, with cargo build, and then run cargo test to check if the tests are still passing.

BACnet server app

Hi can you make a BACnet server app from this? This code below doesn't work but curious if it would be hard putting something together like did with the BACnet client apps in rust? The idea would be to just make one AnalogValue point with a fake temperature sensor reading. I dont know enough on the C stack to complete it curious if you had any ideas?

#include "bacnet/basic/sys/mstimer.h"

#include "bacnet/datalink/bip.h"
#include "bacnet/basic/object/device.h"
#include "bacnet/basic/object/av.h"
#include "bacnet/datalink/bip.h"


static struct mstimer Update_Timer;
static float space_temperature = 24.5;

void Analog_Value_Init(void) {
    static bool initialized = false;
    if (!initialized) {
        initialized = true;
        Analog_Value_Create(0); // Instance 0
        Analog_Value_Units_Set(0, UNITS_DEGREES_CELSIUS);
        Analog_Value_Present_Value_Set(0, space_temperature, 10);
    }
}

void Update_Analog_Value(void) {
    mstimer_reset(&Update_Timer);
    space_temperature += 0.1;  // Update the temperature for simulation
    Analog_Value_Present_Value_Set(0, space_temperature, 10);
}

int main(void) {
    BACNET_ADDRESS src = {0};  // source address

    Device_Set_Object_Instance_Number(12345); // Set device instance number
    bip_init(NULL);  // BACnet/IP initialization
    Analog_Value_Init();  // Initialize the Analog Value object

    mstimer_set(&Update_Timer, 1000);  // 1 second timer

    while (1) {
        bip_network_layer_task();  // BACnet tasks
        if (mstimer_expired(&Update_Timer)) {
            Update_Analog_Value();
        }
    }
    return 0;
}

And a Makefile???
