# Useful commands

# ps -e -o class,rtprio,pri,nice,cmd

# ps H -q `pidof -s rotenc` -o 'pid,tid,cls,rtprio,comm'

# NOTE: the RTPRIO col applies to real-time scheduler policies, the NI (nice) and PRI columns are for non real-time policies



# for rotenc process

LimitRTPRIO=50

LimitRTTIME=infinity



# scheduling policy

# real-time

# - fifo, first in first out

# - rr, round robin

# static

# - other, the standard round-robin time-sharing (ts) policy

# - batch, for "batch" style execution of processes

# - idle, for running very low priority background jobs

CPUSchedulingPolicy=other



# scheduling priority

# 1 = lowest, 99 = highest)

CPUSchedulingPriority=42



# scheduling priority adjustment

# applies only to static scheduling policies

# 0 = default, -20 = highest, 19 = lowest

Nice=-10



# processor affinity bit mask

# - empty string = reset bit mask

# - cpu index list or dash seperated range

#CPUAffinity=0,1



# Launch params

# rotenc <poll_interval in ms> <accel_factor> <volume_step> <pin_a> <pin_b> <print_debug>

# rotenc 100 2 3 23 24 1 (with optional debug print)

# rotenc 100 2 3 23 24 (normal)

# poll_interval:    Number of ms delay for each iteration of the volume update loop. Default=100

# accel_factor:        Threshold (difference between last and current position of encoder) to determine whether to use 1 step or STEP steps. Default=2.

# volume_step:        Number of steps to use when knob turns at fast rate. Default=3.

# pin_a/b:            GPIO pin numbers. Defaults: rotenc_py (23,24 - Broadcom SoC), rotenc_c (4,5 wiringPi).

# print_debug:        Print debug information to console. 1=normal, 2=verbose (2 is for rotenc_c only). This is an optional param.
