The firmware for the Holoseat can be found in the SVN Repository. Its basic function is to detect pedal events from the sensor, use the timing of those events to determine the cadence (in RPM), and then send the walk command (generally by pressing the 'w' key) when the pedal speed is greater than the specified trigger speed.
The default parameters for the firmware are stored in the holoseat_constants.h file so they will be available at start up without the need for a connection to the desktop control application. The desktop control application modifies the default values by updating the values of the corresponding constants in this file and then flashing updated firmware to the Holoseat. The following parameters have default values in the constants file.
The HoloSeat firmware has a serial protocol to enable the desktop control application to modify all key parameters and to determine the current configuration of the Holoseat.
