⚡Program Function Description<span><span>The function and principle of this program are as follows:</span></span>
System design requirements: Design an FPGA to control a digital clock that displays static and dynamic LED lights. The NBW-8 host can connect to 8 sub-units and has the following functions:
1. The host has LED display: The host uses a display screen to show the nursing level and system status. The host panel has 16/8 bi-color LED indicators that can display the working status of each sub-unit.
2. Continuous calling: The host can display calls from multiple sub-units and retain memory.
3. Secondary nursing: The nursing level can be designed on the host, with high-level and ordinary nursing levels.
4. Parallel function: The host has a parallel function, allowing multiple hosts to be connected to achieve multi-pole management.
5. Each sub-unit is connected to the door light.
After properly connecting the wires and ensuring correctness, turn on the host power. The host automatically enters the checking state for the sub-units, starting detection from unit 1: the sub-units display normally and flash briefly. If a certain sub-unit has a fault or is not connected, the corresponding route indicator light will turn green and remain on. After checking all 16/8 sub-units, the indicator lights that remain green will stay on for 5 seconds before turning off. After the check is complete, the host automatically returns to standby mode.
