V2 - Front panel LED freezes
During front panel debugging, I came across a problem where the front panel LEDs jammed and they were not responding to any commands sent by the I2C link nor even powering down the module removed this problem. When a LED was lid for a long time and the power was switched off, and then quickly powered back on again, the LED was still on. This is probably caused by a capacitor that is charged and the discharge time is slow. To be investigated.
