    摘要: A serial bus data transfer system employs an interface circuit which includes a first FIFO which receives data from a serial bus and a second FIFO which outputs data to the bus. A first processor interfaces with the FIFOs and a dual-banked shared memory comprising first and second memory banks, such that data is routed between the FIFOs and the memory banks via the first processor. A second processor interfaces with the dual-banked shared memory such that data can be bidirectionally exchanged between either memory bank and the second processor. The first memory bank can be accessed and clocked by the first processor while the second memory bank is simultaneously accessed and clocked by the second processor, and vice versa, such that data can be simultaneously transferred between the FIFOs and the second processor via the dual-banked shared memory.

    摘要: A sun meter having a processor receiving a signal from a photocell. The processor first compares the signal to a first threshold to determine if it is daytime. If it is daytime, the processor then compares the signal to a second threshold to determine if the signal is greater than a value selected to correspond with direct sunlight. If the signal is greater than the second threshold, a counter counts. For each day of use, the amount of time of direct sun is tallied and may be displayed. An average amount of direct sun for a period of days may also be displayed. It is anticipated that a plurality of meters will be utilized in a specific area to determine the specific locations which receive the most direct sunlight and then know what plants will thrive and where to place such plants.
