RE: RPN Scientific Firmware for the Spikenzielabs Calculator Kit
I have found something in the code that I don't understand:
// KeyPad Layout: // // Columns Rows // 3 2 1 0 // // 7 8 9 / 0 // 4 5 6 * 1 // 1 2 3 - 2 // 0 . = + 3 // // Value mapping for decoding // 12 8 4 0 // 13 9 5 1 // 14 10 6 2 // 15 11 7 3 // // ascii values returned // 7 8 9 / // 4 5 6 * // 1 2 3 - // 0 . = + // // shifted ascii values returned (i.e. dp key held down while other key pressed) // A B C D // E F G H // I J K L // na na na na (bottom row not used for shifted keys, since the dp key is in this row) ... so far, so good, but later we can read: case 3: keyvalue = 'P'; // shift '+' break; Does anybody know why this "case 3:" was included in the code? I wish I could use that shift '+' to include the bigln that is left as a comment at the end of the source code. Thanks in advance for any prospect clue.
