Can microSD card be accessed in UIFlow or with MicroPython?
-
I can not find any instruction in the documentation regarding how to access the tf card with python.
Can anyone help me?
-
Take a look at the micro python official forums, there is a discussion about it
-
Not possible in uiflow yet. Micropython is easy
import os
os.mountsd()
os.listdir('/sd')etc...

@lukasmaximus
thank you for your reply.
But when I tried to exec os.mountsd I got an error as below.os.mountsd()
W (20141) sdspi_host: spi bus changed (1 -> 2)
E (20141) sdspi_host: spi bus 2 not available
E (20141) vfs_native: Failed to initialize SDcard (258).
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 5] EIO

I just exec in REPL.
import os
os.mountsd()nothing else....
I also tried os.SDMODE_4LINE, os.SDMODE_1LINE and os.SDMODE_SPI with os.sdconfig(...) before mountsd(), but none of them worked.
Forgot to say, I'm using M5Stack Fire.

You also need the machine, sdcard and dpi library imported. That’s why I recommend that you visit MicroPython.org

thank you.
I went to MicroPython.org but found nothing helpful.
Finally, I erased the firmware and burned the M5S with the UIFlow-v1.3.1-Beta firmware.It worked, with the code below.
>>> import uos >>> uos.sdconfig(uos.SDMODE_SPI,clk=18,mosi=23,miso=19,cs=4) I (53596) gpio: GPIO[23]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pull down: 0| Intr:0 I (53596) gpio: GPIO[19]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pull down: 0| Intr:0 I (53604) gpio: GPIO[18]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pull down: 0| Intr:0 >>> uos.mountsd() W (65959) sdspi_host: spi bus changed (1 -> 2) I (65959) gpio: GPIO[4]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 0| Pulld own: 0| Intr:0 --------------------- Mode: SPI Name: SU08G Type: SDHC/SDXC Speed: default speed (25 MHz) SPI speed: 40 MHz Size: 7580 MB CSD: ver=1, sector_size=512, capacity=15523840 read_bl_len=9 SCR: sd_spec=2, bus_width=5 >>>

Funny...
I re-burned back to UIFlow-v1.2.3, and it also worked.

ok......
now even one simple uos.mountsd() also works...
good...>>> import uos >>> uos.mountsd() W (497494) sdspi_host: spi bus changed (1 -> 2) --------------------- Mode: SPI Name: SU08G Type: SDHC/SDXC Speed: default speed (25 MHz) SPI speed: 20 MHz Size: 7580 MB CSD: ver=1, sector_size=512, capacity=15523840 read_bl_len=9 SCR: sd_spec=2, bus_width=5
