// how much tolerance do we allow if we charge / discharge before we 
// trigger the control loop to adjust the value

// Mainloop sleep time
// Time to sleep between two mainloop intervals
// We have a 32 MHz clock
// debugging e.g. 32000000*5 -> 5s
// production e.g. 320000 (10ms) (Validate that this is really the case!)
// should be large for debugging, (e.g. )
// small for production

// avoid EMV peaks
