LumiDrive LED Driver doesn't mount any partition

[krish_iyer]

Hey,

I was playing around with LumiDrive LED Driver. The arduino code which was linked in hookup guide didn’t show any results at that time hence I tried changing the DATA_PIN and CLOCK_PIN.

Previous:

#define DATA_PIN 16

#define CLOCK_PIN 17

Changed:

#define DATA_PIN 27

#define CLOCK_PIN 28

Now, the usb drive and partition disappeared. I can try to reflash the bootloader and bring back to the initial state but I failed to find any referrences for that.

Also, my application required threading in python(it required reading from the console and a operation loop in parallel for keeping blinking operation alive until a request for any other pattern is input in the console) but I don’t think circuit python supports threading hence eventually I have to go for arduino and FastLED but I need to communicate serially over USB. And I don’t know which Serial to select or any require any additional settings.

Let me know if anyone has any view on this.

Thanks

Please see the [Python Example Code section in the hookup guide for instructions on how to recover the board after using it in Arduino.](https://learn.sparkfun.com/tutorials/lumidrive-hookup-guide#python-example-code)

Yes, I saw that but my device itself is not getting detected. USB port doesn’t show and nor does the partition drive. I think I know what went wrong, I added a “Serial.begin(115200)” and that made USB disconnect forever.

If you upload to the board in Arduino, you will erase the firmware on the board that enables the USB flash drive.

Did you follow the steps in the yellow box in the link I sent previously?
