Summary This application is calculator that can be calculation of hexadecimal and CRC.1. About Calculator for hexadecimal. Calculation has 3 modes. At a time, hexadecimal and decimal and binary is displayed. Hexadecimal mode: arithmetic calculation and logical, and bits shift. Decimal mode: arithmetic calculation of real number. Binary mode:logical, and bits shift. It support signed 32 bit integer. Calculatalculation is carried out in input order. (Multiplication and division has no priority.) Ex.) 2 + 2 * 2 = 8 Only decimal mode, it can use real number. Other mode is fraction truncate. Press and hold display, result is copied to clipboard. (only decimal and hexadecimal) Cannot paste from clipboard.2. About Calculator for CRC. CRC is calculated from two generating polynomials. CCITT mode:for calculation of CRC-16-CCITT. CRC16 mode:for calculation CRC-16-IBM. Calculation result is shift right, shift left and each inversion. In addition to input by manual, it can input from text file. In text file, its format must add linefeed at each byte. Blank line is judged as “00”. At one character only, padded “0” to higher digit. If over three characters, first two characters is used. Available letters is from “0” to “9” and from “A” to “F” and from “a” to “f”. ex） 03 -> 03h 56 -> 56h 7AB -> 7Ah E -> 0Eh -> 00h aa -> AAh [EOF] -> 終了How to use. Calculator for hexadecimal. Arithmetic calculation Input numeric value and “=” , Calculation result is displayed. Logical operator(only hexadecimal mode and binary mode). Input numeric value and logical operator(and, or, xor), Calculation result is displayed. Input numeric value and other operator(shift, not), Calculation result is displayed. For a result, it can calculate. Calculator for CRC. Setting for initilal value. Tap display area for initilal value. Input initial value. Tap “init” button. Set initial value. Calculator for CRC. Confirm input area is red. Input value of two characters, and tap “=” button. In result area, it will be displayed CRC at each bytes. Calculation result be displayed each time tap “=” button after input values. At display area, four results display shift left. inversion of shift left. shift right. inversion of shift right.Extra function. Backcolor property.
