Driver and Firmwares,


In this Document you will find the Windows Drivers and firmware's for the Geek Pulse units. This firmware chart will get updated once we have finalized a new firmware and Driver periodically. Please note we do not recommend you changing your firmware because there is a risk that you might brick your unit. The firmware provided upon receiving was selected to be the best firmware for your batch.


What the Pulse Firmware breakdown means:


The Pulse unit has three internal points for firmware. The display board or MCU is responsible for your Menu, Display, Volume control, and IR port. This can only get updated in-house.


The USB firmware is responsible for the musical data communication. It controls the USB sampling, DSD over PCM, PureDSD and all other music data formats. This can be seen using the Light Harmonic Control Panel.


The Main firmware is the overall architecture for the display, processor, and DAC communication. The only firmware that cannot get updated in the field is the MCU or Display Board. By using the Device Firmware Update utility or DFU you can flash your Pulse with the latest updates via USB.


Our Firmware breakdown table will show you all of our current firmware for all three major points.






Caution:

  •   Please do not use any of the firmwares provided for any other product.
  •   The Geek Out and Pulse firmwares ARE NOT INTERCHANGEABLE (You will brick your unit.)
  •   If you do brick your unit, this is not covered under warranty. It will be at the customer's expense to repair the unit. 
  •   Our Driver and firmware are created to only work for LH Labs products. Please do not attempt to use on other XMOS platforms.



This document also provides the Light Harmonic 2.29 Driver found in the spreadsheet. You will need to install driver version 2.29 for use with any new devices such as

Geek Out V2
