Running code with ampy or rshell or REPL?

dclaar

I'm trying to streamline the debug cycle. Since vscode doesn't have a serial console (does it?) I run my code from there, it fails, then I have to stop that, go to putty, see what the error was, quit putty, reconnect vscode...

I tried a couple of suggestions I found here: ampy & rshell, but couldn't get them to work.

I have a file /flash/apps/purple_air.py. I can't seem to run it. If I start rshell, there's no run command. If I try using the shell command:

cd /flash/apps
shell purple_air.py

It opens the file in vscode. But since vscode isn't connected to the com port, the run icon doesn't work.

From ampy, the run command can't seem to find imports, but when I run from vscode or via the apps interface on the m5stickC, it works just fine. My imports:

from m5stack import *
from m5ui import *
from uiflow import *
import imu
import wifiCfg

Ampy:

ampy -pcom4 run purple_air.py
Traceback (most recent call last):

Oh, I can:

import apps.purple_air as pa
pa.main()

Vcode does have a series console that you can use to run REPL through.

You could also try Mu. It may not have all the features that vscode has but it has a nice clean interface and works for transferring files between computer and m5stack, REPL, and has autocomplete for micropython base modules, i made a video on it a couple of weeks ago https://www.youtube.com/watch?v=GPRNUCBTVy4&t=6s

@lukasmaximus I read that Mu requires 1.5.0, and I also read that it isn't out yet for the M5StickC.
@ajb2k3 I sure haven't been able to find it!

@ajb2k3 Adding to this: I'm using the pymakr extension to VS Code. It handles selective code upload (only changed ones).

Note that pymakr does not handle binary file transfer eg. jpg.
