Hi In my project iam measuring the leak rate. The range of leak rate is 1.0E-11 to 1.0E-02.Up now I measured leak rate and displayed On the 7 segment display with 0.1 resolution. Here I used look up table method I taken hole Range values In the table and iam displaying the value for corresponding voltage . I stored values in the farm Of (1011 =1.0E-11) here "." ,"E","-" are constants. Now I want display the leak rate on BAR graph display. For 20 digits I have to take one led. The fallowing values I have to show on bar graph 1E-11, 3E-11, 5E-11, 7E-11, 9E-11, 1E-10, 3E-10, 5E-10…………………………………………2E-02 ex: 1E-11 = one led should glow 3E-11 = 2 leds should glow 5E-11 = 3 leds should glow : : : How to convert table values in to bar graph display. Thanks Regards
"EX: 0000 0001 – led1 glow 0000 0011 – led2 glow 0000 0111 – led3 glow 0000 1111 – led4 glow 0001 1111 – led5 glow 0011 1111 – led6 glow 0111 1111 – led7 glow 1111 11111 – led8 glow" Do you mean:
0000 0001 – LED 1 glows 0000 0011 – LEDs 1,2 glow 0000 0111 – LEDs 1,2,3 glow 0000 1111 – LEDs 1,2,3,4 glow 0001 1111 – LEDs 1,2,3,4,5 glow 0011 1111 – LEDs 1,2,3,4,5,6 glow 0111 1111 – LEDs 1,2,3,4,5,6,7 glow 1111 1111 – LEDs 1,2,3,4,5,6,7,8 glow
0000 0001 – LED 1 glows 0000 0010 – LED 2 glows 0000 0100 – LED 3 glows 0000 1000 – LED 4 glows 0001 0000 – LED 5 glows 0010 0000 – LED 6 glows 0100 0000 – LED 7 glows 1000 0000 – LEd 8 glows
