SD CARD Mount Sample Code

[spienz]

Hey Folks,
as diskussed with @kdschlosser some sample for mounting SDCARD.

Greetings

Sebastian

from machine import SPI, SDCard
import vfs


# Initialize the SPI bus with appropriate pins
spi_bus = SPI.Bus(
    host=2,        # SPI bus host number (adjust based on your board)
    mosi=11,       # Master Out Slave In (adjust based on your hardware)
    miso=13,       # Master In Slave Out (adjust based on your hardware)
    sck=12         # Clock pin (adjust based on your hardware)
)


sd = None

while sd is None:
    try:
        sd = machine.SDCard(
            spi_bus=spi_bus,
            cs=10,
            freq=1000000
        )
        vfs.mount(sd, "/sd")
        print('Flash Mounted')
        print(os.listdir('/sd'))
    except Exception as er:
        sd = None
        print('sd card failure')
        time.sleep(5)

I upload firmware to ESP32 LCD from
python3 make.py esp32 --partition-size=2560000 BOARD=ESP32_GENERIC DISPLAY=ILI9341 INDEV=XPT2046

And I tested this sample code on ESP32 LCD but it restart with error
from machine import SPI, SDCard
import vfs
import time
import os

Initialize the SPI bus with appropriate pins

spi_bus = SPI.Bus(
host=2, # SPI bus host number (adjust based on your board)
mosi=23, # Master Out Slave In (adjust based on your hardware)
miso=19, # Master In Slave Out (adjust based on your hardware)
sck=18 # Clock pin (adjust based on your hardware)
)

sd = None

sd = SDCard(
spi_bus=spi_bus,
cs=5,
freq=1000000
)

vfs.mount(sd, "/sd")
print('Flash Mounted')
print(os.listdir('/sd'))
