@lukasmaximus Hey lukas, on which firmware version did you make this run?

I am running it on a M5Core Basic and the unit reboots after the .wav was played once and I hit the button again.

I have to uncomment:
uos.sdconfig(uos.SDMODE_SPI,clk=18,mosi=23,miso=19,cs=4)

to avoid another error

still I get the:
"sd card not mounted" lcd print.

Is there any chance to adapt this patch to a newer firmware version?

I have also tried it on a Core2, but it doesn't seem to know any of the I2C modes which you defined.

would be great to get this to work again and make/update custom uiflow blocks.

Thanks in advance for your reply
