1000 | * flash_strobe_adjustment E N, [1 - 0xff] | |
1001 | * | |
1002 | * The formula above is written as below to keep it on one | |
1003 | * line: | |
1004 | * | |
1005 | * l / 10^6 = w / e * a | |
1006 | * | |
1007 | * Let's mark w * a by x: | |
1008 | * | |
1009 | * x = w * a | |
1010 | * | |
1011 | * Thus, we get: | |
1012 | * | |
1013 | * x = l * e / 10^6 | |
1014 | * | |
1015 | * The strobe width must be at least as long as requested, | |
1016 | * thus rounding upwards is needed. | |
1017 | * | |
1018 | * x = (l * e + 10^6 - 1) / 10^6 | |
1019 | * ----------------------------- | |
1020 | * | |
1021 | * Maximum possible accuracy is wanted at all times. Thus keep | |
1022 | * a as small as possible. | |
1023 | * | |
1024 | * Calculate a, assuming maximum w, with rounding upwards: | |
1025 | * | |
1026 | * a = (x + (2^16 - 1) - 1) / (2^16 - 1) | |
1027 | * ------------------------------------- | |
1028 | * | |
1029 | * Thus, we also get w, with that a, with rounding upwards: | |
1030 | * | |
1031 | * w = (x + a - 1) / a | |
1032 | * ------------------- | |
1033 | * | |
1034 | * To get limits: | |
1035 | * | |
1036 | * x E [1, (2^16 - 1) * (2^8 - 1)] | |
1037 | * | |
1038 | * Substituting maximum x to the original formula (with rounding), | |
1039 | * the maximum l is thus | |
1040 | * | |
1041 | * (2^16 - 1) * (2^8 - 1) * 10^6 = l * e + 10^6 - 1 | |
1042 | * | |
1043 | * l = (10^6 * (2^16 - 1) * (2^8 - 1) - 10^6 + 1) / e | |
