@felmue said in M5Paper SDCard access:

isd = SPI(-1, miso=Pin(13), mosi=Pin(12), sck=Pin(14))
sd = SDCard(spisd, Pin(4))
os.mount(sd, '/sd')
print(os.listdir('/sd'))

Doesnt work for me ( it works for printing in thonny ... but the device freezes)

@felmue I tried the core gray

guess I will try again and report back if it works.

Ideally the the new m5 stamps will works as well with coming updates ?

@mrk I figured it out...

turns out you dont need to mount at all just do

import json

with open('/sd/config.json', 'r') as fs:
c = json.loads(fs.read())
label0 = M5TextBox(140, 106, c['ssid'], lcd.FONT_Default, 0xFFFFFF, rotate=0)

I may have run some code prior to that .. dont remember .. try that if the first thing didnt work .. ( this is from boot.py) ... maybe it gets added automatically

import machine, os
try:
    sd = machine.SDCard(slot=3, miso=19, mosi=23, sck=18, cs=4)
    sd.info()
    os.mount(sd, '/sd')
    print("SD card mounted at \"/sd\"")
except:
    pass

.

import uos

uos.sdconfig(uos.SDMODE_SPI,clk=18,mosi=23,miso=19,cs =4)

uos.mountsd()

@m5stack I tried the

import deviceCfg
deviceCfg.get_board_name() 

it throws an error ....

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "deviceCfg.py", line 270, in get_board_name

TypeError: string indices must be integers, not str

I tested all the other functions of deviceCfg and they all work ...
but the one I asked you to add does not....

hanks for implementing it .. but it doesnt work ;)

@zontex nice .. finally smth I can debug with easily

@titimoby thanks I figured out how to use mu now with your video

@dclaar thanks man :D ... I forgot this existed ...
also no im atm exploring options to improve debugging on m5stack ...
if you have any advice please let me know ...

Basicly I just want some way where I can run the code on devices with no screen .. and show me the errors .

I tried mu .. but it doesnt seems to work on m5stack firmware ... same with ampy ... the "ls" command just freezes the prompt and doesnt show the directories -.-...

the only serial connection I managed so far was via putty..

Working on a little project to display notifcations on the m5 core devices...
So maybe I will flash the micropython firmware instead of using uiflow ...
I like uiflow though .... makes testing & developing stuff very nice

So far ive printed errors to the screen...
But using the atom lite models lately ... I struggle with debugging.

When I run custom code via UIFLOW ... how can I get acces to error messages ? prints etc ....

May I ask how you found out about the methods names ?

I dont think they are up for reading on github right ?
