## Purpose
This tool allows you to flash a VESC via CAN-bus or serial/USB using Python.
## Installation and running
To install:
```bash
pip install .
```
Or install the latest release from PyPI:
```bash
pip3 install -U pybldc
```
### CLI
A handy CLI tool is included:
```bash
$ 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
```
__Upload__
```
pybldc can upload -id 1 -B VESC.bin
```
```
pybldc serial upload -p /dev/ttyACM0 -B VESC.bin
```
__Ping__
```
pybldc can ping -id 1
```
```
pybldc serial ping -p /dev/ttyACM0
```
__Reset__
```
pybldc can reset -id 1
```
```
pybldc serial reset -p /dev/ttyACM0
```
#### Increase TX buffer
On Linux you might need to increase the TX buffer size:
```bash
sudo ip link set can0 txqueuelen 1000
```
