| 22 ; HISTORY | |
| 23 ; 2010-12-02 : [jDG] Creation... | |
| 24 ; | |
| 25 ; RATIONALS for STRCAT / STRCPY / STRCAT_PRINT / STRCPY_PRINT: | |
| 26 ; * Gain PROM space: each time a string operation is done, we have a bunch | |
| 27 ; of lines in the style: | |
| 28 ; movlw '+' | |
| 29 ; movwf POSTINC2 | |
| 30 ; movlw '/' | |
| 31 ; movwf POSTINC2 | |
| 32 ; movlw '-' | |
| 33 ; movwf POSTINC2 | |
| 34 ; movlw ':' | |
| 35 ; movwf POSTINC2 | |
| 36 ; call word_processor | |
| 37 ; which takes 20 bytes of PROM space (eg. 4 + chars/4). Whereas : | |
| 38 ; STRCAT_PRINT "+/-:" | |
| 39 ; takes just 10 bytes (4 + chars + 1, even rounded up). | |
| 40 ; | |
| 41 ; Note that the other common sequence : | |
| 42 ; OUTPUTTEXT .113 | |
| 43 ; does compile in (6 bytes per call), plus (1 + chars, even rouded up) | |
| 44 ; once it the whole code. Also, it is slower to execute, because it have | |
| 45 ; to roll through the string table. | |
| 46 ; | |
| 47 ; RATIONALS for a formating variant... not yet done... | |
| 48 ; * Embeding formatting commands into the string allows even mode compact | |
| 49 ; sequence. | |
| 50 ; Possible commandes: | |
| 51 ; \xF0 output_8 ; arg in hi, and move lo to hi, | |
| 52 ; \xF1 output_9 ; so we can have two 8bits concertion | |
| 53 ; \xF2 output_99 ; in a single sequence... | |
| 54 ; \xF3 output_99x | |
| 55 ; \xF4 output_16 ; arg in hi:lo | |
| 56 ; \xF5 output_16dp 1 | |
| 57 ; \xF6 output_16dp 2 | |
| 58 ; \xF7 output_16dp 3 | |
| 59 ; .... | |
| 60 ; Usage: | |
| 61 ; movff apnoe_min, hi | |
| 62 ; movff apnoe_sec, lo | |
| 63 ; FORMAT_PRINT "Time: \xF3:\xF3" | |
| 64 ; | |
| 65 ; * Cons: code redeability is poor: reader have to remember exactly what | |
| 66 ; each cryptic hexa code is doing... | |
| 67 ; No-macro-syntax: | |
| 68 ; call format_print_block | |
| 69 ; DB "Time: ", FORMAT_99x, ':', FORMAT_99x, 0 | |
| 70 ; is denitively more secure in that respect... | |
| 71 | |
| 72 ;============================================================================= | |
| 73 ; Copy a short embebed string at start of the string buffer (letter) | |
| 74 ; Input: (nothing) | |
| 75 ; Output: chars are copied into letter, starting at the beginning. | |
| 76 ; FSR2 point to the first unused char (the NULL termination). | |
| 77 ; | |
| 78 ; Trashed: WREG, TBLPTR, TABLAT, PRODL | |
| 79 ; Note: This are all bank-safe call. | |
