preenfm2 and preenfm3 / Backup and Restore Function

« on: April 03, 2021, 06:03:54 AM »

I love the sounds and the presets that I have been able to implement on my Preenfm3 since I built it a few weeks ago!

So... that leaves me with another question-
Is there some sort of way that I may save the complete group of 6 instruments, the presets and mixers to a system file on the SD card.  The setup.txt file should have a way to tell the Preenfm3 at power-up to load the saved image file from the SD card, if it exists!

Each time I cycle the power, my device comes up cleared to initial setup defaults.  Is there a way to backup and restore a system image after power cycling?

preenfm2 and preenfm3 / [solved] SD Card Issues...

« on: March 21, 2021, 05:30:28 PM »

I have just finished assembly of my PreenFM3 and I cannot get the SD card to function.  I am running V0.105 and am powering the unit from the USB connection.  I am using one of the recommended "Sandisk Ultra - SDHC UHS-I Card" 16GB card.  It has been formatted as FAT32 by the recommended "SD Card Formatter" program.

The Preenfm3 appears to be functioning well as I am able to use the editor and MIDI ports and generate tones etc.  It only appears to be that the SD Card is not functioning.

I loaded the pfm2_usb.zip onto the SD Card and then tried moving the contents to a /pfm3/ subdirectory on the card using my laptop.

I have a few of questions:
1. Is the SD Card supposed to be r/w accessible to my computer as a typical memory card?
2. What is the expected directory structure for the files on the SD Card when used on my PreenFM3?
3. I get an error code of #-6# on the tft at powerup of the Preenfm3.  Is it possible that I have a jumper incorrectly strapped that would cause this to occur?  It appears that the connectors and operation of the tft are working correctly as a display. The SD connector on the display is present and connected to the Preenfm3.

Any comments or suggestions would help!  Thank you...
