Install

go install github.com/kinpoko/easerial@latest

Usage

`easerial string`

easerial string <string> [--port <port name>] [--baud <baud rate>] [--data-bits <data bits>] [--read-bytes <read bytes>] [--read-timeout-sec <read timeout sec>]

<string>: Required. The string to send as hex data.
--port: Optional. The serial port to use. Defaults to /dev/ttyUSB1.
--baud: Optional. The baud rate to use. Defaults to 9600.
--data-bits: Optional. The number of data bits to send. Defaults to 8.
--read-bytes: Optional. The number of reading bytes after sending. Defaults to 4.
--read-timeout-sec: Optional. The number of seconds of timeout for reading serial port after sending. Defaults to 1.

Example:

easerial string 68656c6c6f20776f726c64 --baud 115200 --port /dev/ttyUSB0

`easerial file`

easerial file <file_path> [--port <port name>] [--baud <baud rate>] [--data-bits <data bits>] [--read-bytes <read bytes>][--read-timeout-sec <read timeout sec>]

<file_path>: Required. The path to the file send as a hex data.
--port: Optional. The serial port to use. Defaults to /dev/ttyUSB1.
--baud: Optional. The baud rate to use. Defaults to 9600.
--data-bits: Optional. The number of data bits to send. Defaults to 8.
--read-bytes: Optional. The number of reading bytes after sending. Defaults to 4.
--read-timeout-sec: Optional. The number of seconds of timeout for reading serial port after sending. Defaults to 1.

Example:

easerial file helloworld.txt --baud 115200 --port /dev/ttyUSB0
