## README

# This is the python wrapper for GCAN driver

## How To Use

### without python-can

  ```python
from gcan import GCan, DeviceType, CAN_FRAME

can = GCan(DeviceType.USBCAN2, 0)
can.OpenDevice()
can.InitCAN(0, bitrate=500_000)
can.StartCAN(0)

frames = (CAN_FRAME * 1)()
frames[0].ID = 0x00
frames[0].SendType = 0x00
frames[0].RemoteFlag = 0x00
frames[0].ExternFlag = 0x01
frames[0].DataLen = 0x08

for i in range(8):
    frames[0].Data[i] = i
    
can.Transmit(0, frames)

# do other thing

can.ResetCAN(0)
can.CloseDevice()
  ```

### with python-can
  * move `gcan.py` to python-can library path: `interfaces`
  * add `"gcan", ` to `interfaces/__init__.py`'s `__all__`
  * add `"gcan": ("can.interfaces.gcan", "GCanBus"),` to `interfaces/__init__.py`'s `BACKENDS`
  
  ```python
import can
from gcan import DeviceType

with can.Bus(interface="gcan", device_type=DeviceType.USBCAN2, device_index=0, configs=[
    {"bitrate": 500_000}, {"bitrate": 1_000_000}
]) as bus:
    print(bus.recv())
  ```
