Detailed Description

The leds namespace provides all necessary facilities related to the logical model of the sets of LEDs on the MMU unit.

We have 5 pairs of LEDs. In each pair there is a green and a red LED.

A typical scenario in the past was visualization of error states. The combination of colors with blinking frequency had a specific meaning.

The physical connection is not important on this level (i.e. how and what shall be sent into the shift registers).

LEDS are physically connected to a pair of shift registers along with some other signals. The physical write operations are handled by hal::shr16.

Mode

enum modules::leds::Mode

Enum of LED modes blink0 and blink1 allow for interlaced blinking of LEDs (one is on and the other off)

Enumerator
blink0	start blinking at even periods
blink1	start blinking at odd periods
