/*
|
||||
bug fix where Blinking RED would not change led_color back --> global/local definiton
|
||||
ToDo: Different PCB-Layout, sodass RGB LED beim Flashen nicht leuchten.
|
||||
Changelog:
|
||||
18.02.17:
|
||||
CHANGE: Add EEPROM_DEBUG defined block. Need to be compiled with -O3 Flag
|
||||
INFO: ledcolor==3 block is obsolete. Could be removed to save space
|
||||
23.06.17:
|
||||
CHANGE: comment out ledcolor==3 block
|
||||
reduce brighness to 100 for green and red
|
||||
INFO: MicroCore 1.0.2 creates very small binary, suspious
|
||||
25.05.18:
|
||||
CHANGE: reduce the used flash
|
||||
ADDED: max red temp per session
|
||||
FIXED: lowered red, green led intensity
