# STM32duino_CAN_Library

CanBus library for STM32F103 running on STM32duino, tested on F103C8T6 variant.

Key advantages:

* Object-oriented programming style

* Support for inline Can::Frame initialization

* Support for 33.3KBPS CAN (GMLAN/SWCAN)

Inner workings based on [nopnop2002](https://github.com/nopnop2002/Arduino-STM32-CAN/tree/master/stm32f103)'s sketch.

## Supported board / Can-Bus parameters:

STM32F103 pinouts:

```cpp

enum Can::Pinout {

  RX_PA11_TX_PA12,  // 36/48/64/100/144 pin packages

  RX_PB8_TX_PB9,    // 48/64/100/144 pin packages

  RX_PD0_TX_PD1,    // 100/144 pin packages

};

```

Bitrates:

```cpp

enum Can::Bitrate {

  CAN_33K3BPS,

  CAN_50KBPS,

  CAN_100KBPS,

  CAN_125KBPS,

  CAN_250KBPS,

  CAN_500KBPS,

  CAN_1000KBPS,

};

```

## Can-Bus frame:

```cpp

class Can::Frame {

public:

  uint32_t id;

  uint8_t length;

  uint8_t data[8];

  FrameFormat format;

  FrameType type;

}

```

Types and formats:

```cpp

enum Can::FrameFormat {

  Standard,

  Extended, 

};

enum Can::FrameType {

  Data,

  Remote,

};

```

## Example usage:

```cpp

#include "CanBus.hpp"

using namespace Can;

CanBus can0;

void setup() {

  Serial.begin(9600);

  bool ret = can0.begin(Bitrate::CAN_33K3BPS, Pinout::RX_PB8_TX_PB9);

  Serial.println(ret ? "BOOT OK" : "BOOT FAILURE");

  if (!ret) while(true);

}

Frame rx;

Frame tx = { 0x7FF, 3, {0x01, 0x02, 0x03} };

void loop() {

  if(can0.checkReceive()) {

    can0.receive(&rx);

    rx.print();

  }

  tx = { 0x17FF, 3, {0x01, 0x02, 0x03}, FrameFormat::Extended, FrameType::Data };

  can0.send(&tx);

}

```
