Price to time part of lookup table |
The whole meter system can break up as three parts
1) coin receiver This parking system can accept coin, paper currency and visa card.(Paypal and apple pay will be added at future parking meter edition :-) ) After recognized the coin type, our look up table can convert the 1/5/10/25/50 cent and 1 dollar coin signal to time value, feed them to a mux, sum up and have the total time value. 2) tally I use a 16-bit subtractor, it will subtract 1 every second. 3) output in order to show the real hours/minutes/seconds. I designed two ROM lookup table. it can convert the binary to hours minutes and seconds. |
