목적

이 도구를 사용하면 Python을 사용하여 CAN 버스 또는 직렬/USB를 통해 VESC를 플래시할 수 있습니다.

설치 및 실행

설치하려면:

pip install .

또는 PyPI에서 최신 릴리스를 설치하십시오.

pip3 install -U pybldc

CLI

편리한 CLI 도구가 포함되어 있습니다:

$ pybldc -h
usage: pybldc [-id CONTROLLER_ID] [-i INTERFACE] [-l CHANNEL] [-p PORT] [-h] [--version] [-B BINARY] [--bootloader] [-t TIMEOUT] [-r PING_REPEAT] [-b BAUDRATE] [--debug] {can,serial} {upload,ping,reset}

positional arguments:
  {can,serial}          Communicate with the target via either CAN or serial
  {upload,ping,reset}   upload: write BINARY
                        ping: send a ping command to the target and check for a response
                        reset: send a reset command to the target and check for a response

required CAN arguments:
  -id CONTROLLER_ID, --controller-id CONTROLLER_ID
                        The VESC ID used for communication

optional CAN arguments:
  -i INTERFACE, --interface INTERFACE
                        The CAN-Bus interface to use (default " socketcan " )
  -l CHANNEL, --channel CHANNEL
                        The CAN-Bus channel to use (default " can0 " )

required serial arguments:
  -p PORT, --port PORT  The port to use for serial

optional arguments:
  -h, --help            Show this help message and exit
  --version             Show program ' s version number and exit
  -B BINARY, --binary BINARY
                        The binary to upload
  --bootloader          The binary to upload is a bootloader
  -t TIMEOUT, --timeout TIMEOUT
                        The time to wait in seconds for a response (default 5.0)
  -r PING_REPEAT, --ping-repeat PING_REPEAT
                        The number of times to try to establish a connection by pinging the VESC (default 3)
  -b BAUDRATE, --baudrate BAUDRATE, --bitrate BAUDRATE
                        The baudrate/bitrate to use for serial/can (defaults to 115200 for serial and 500000 for CAN)
  --debug               Turn on debug logs

업로드

 pybldc can upload -id 1 -B VESC.bin

핑

 pybldc can ping -id 1

 pybldc serial ping -p /dev/ttyACM0

다시 놓기

 pybldc can reset -id 1

 pybldc serial reset -p /dev/ttyACM0

송신 버퍼 늘리기

Linux에서는 TX 버퍼 크기를 늘려야 할 수도 있습니다.

sudo ip link set can0 txqueuelen 1000
