MicroPython on the ESP8266 (macOS) Part 2

Rshell (Alternative to Ampy)

----------------------------------

Remote MicroPython shell. This is a simple shell which runs on the host and uses MicroPython's raw-REPL to send python snippets to the pyboard in order to get filesystem information, and to copy files to and from MicroPython's filesystem.

Install

sudo pip3 install rshell

Enter:

rshell

Term output:

Welcome to rshell. Use Control-D (or the exit command) to exit rshell.
No MicroPython boards connected - use the connect command to add one

connect serial /dev/tty.wchusbserial1420 115200

(connect serial [port] [baud])

Term output:

Connecting to /dev/tty.wchusbserial1420 (buffer-size 512)...
Trying to connect to REPL connected

etc...

Use Rshell:

----------------------------------

List files on the board

ls /pyboard/

Entering REPL

repl (Use Control-X to exit.)

Upload *.py files

----------------------------------

Copy a file from local directory to esp8266 board

cp main.py /pyboard/

Copy a file from the board to desktop
cp /pyboard/main.py desktop

Run in the REPL

import main

Reset

----------------------------------

There are soft resets and hard resets. A soft reset simply clears the state of the MicroPython virtual machine but leaves hardware peripherals unaffected. To do a soft reset, simply press Ctrl + D on the REPL, or within a script do:

import sys 

sys.exit()

A hard reset is the same as performing a power cycle to the board. In order to hard reset the WiPy, press the switch on the board or:

import machine 

machine.reset()
