| SD2IEC-LCD | ||
| ============ | ||
|
|
||
| This is a fork of the official [SD2IEC](https://sd2iec.de/) firmware, with | ||
| an additional branch for support of LCDs based upon the version introduced | ||
| in the | ||
| [Forum64](https://www.forum64.de/index.php?thread/74116-lcd-sd2iec-firmware-1-0-0-f%C3%BCr-larsp-layout/). | ||
| It also includes changes done by Javi M to support the C64 Version of | ||
| "Another World" and "Wings Of Fury". Original source of this is available | ||
| at [github](https://github.com/jamarju/sd2iec-anotherworld/). | ||
|
|
||
| Branches | ||
| -------- | ||
| These branches are available in this repository: | ||
|
|
||
| - master: contains the original code from [sd2iec.de](https://sd2iec.de/) | ||
| - LCD: (this branch) contains the merged code for LCD versions | ||
| - c128d-internal: contains additional code for a custom C128D | ||
| internal mounted version | ||
|
|
||
| See Also | ||
| -------- | ||
| - [README](README) of the original SD2IEC | ||
| - [README_LCD](README_LCD) for the LCD changes | ||
| - [NEWS](NEWS) referring to the original SD2IEC | ||
| - [COPYING](COPYING) GPLv2 license | ||
|
|
||
| Note | ||
| ---- | ||
| The maintainer of this repository has done this effort, because he's got | ||
| an "evo2"-variant *without* and LCD. So there is no testing possible. | ||
|
|
||
| Pull requests are *very* welcome and will be processed in good faith. | ||
|
|
||
| Special thanks to Ingo Korb and CapFuture1975 and all the others | ||
| contributing to SD2IEC. This is be no means my work. I just had the luck, | ||
| that trying to pull some pieces together worked out pretty well. | ||

||
| Some project history | ||
| ==================== | ||
|
|
||
| This software is based on the sd2iec-0.10.3 software by Ingo Korb. | ||
| First the LCD functionality made by Draco for an older version was added by Seanser. | ||
| Then andi6510 added support for DOGM LCD modules based on a ST7036 controller | ||
| and did some tidy up work by removing all remaining non-LCD related differences | ||
| between Seansers version and the official sd2iec-0.10.3. | ||
|
|
||
| This software was tested on an ATMEGA1284p microcontroller with a ST7036 based | ||
| DOGM162 module and another HD44780 based module (exact type unkonwn). | ||
|
|
||
|
|
||
| New files added on top of sd2iec 0.10.3 | ||
| ======================================= | ||
|
|
||
| lcd.c - low level LCD driver - initial version from draco, andi6510 added lcd auto detection and st7036 support | ||
| lcd.h - low level LCD driver interface | ||
| display_lcd.c - high level LCD functions - initial version from draco, andi6510 added contrast setting for st7036 | ||
| display_lcd.h - high level LCD functions interface | ||
| config-larspLCD - configuration for LarsP hardware with LCD attached | ||
| config-evo2 - configuration for hardware sold as "evo2", a slightly modified sw2 | ||
| README_LCD - this file | ||
|
|
||
|
|
||
|
|
||
| Modified files of sd2iec 0.10.3 | ||
| =============================== | ||
|
|
||
| buffer.c - display "READY" when the last buffer has been closed - seems more a hack and should be replaced with a proper solution | ||
| d64ops.c - display "LOAD" and "SAVE" when files are accessed in a D64 image | ||
| doscmd.c - display various messages on each command - add LCD specific X-commands: XT XA XG XX XC | ||
| eeprom.c - add LCD-contrast setting to eeprom storage | ||
| errormsg.c - display current error message | ||
| fatops.c - display current directory | ||
| fileops.c - display "LOAD" and "SAVE" files (CapFuture) | ||
| main.c - initialise LCD functions, display welcome screen, debug output of detected LCD type | ||
| Makefile - added files display_lcd.c and lcd.c to build process, added prerelease tag LCD | ||
|
|
||
|
|
||
|
|
||
| Additional Commands available via IEC | ||
| ===================================== | ||
|
|
||
| XT* Text Commands | ||
| ----------------- | ||
|
|
||
| The display can be accessed from the c64! | ||
| Use commands "XT1" and "XT2" to send text to display line 1 or 2. | ||
| The addressed line will be cleared before text is printed. | ||
|
|
||
| Example 1 - send "Lightyears ahead!" to line1: | ||
|
|
||
| OPEN15,8,15,"XT1Lightyears ahead!" | ||
|
|
||
| The "XTC" command allows to send a control code followed by data, which makes it possible | ||
| to program the display from the C64 side, e.g. define own characters. | ||
|
|
||
| Example2 - clear the screen: | ||
|
|
||
| OPEN15,8,15,"XTC"+CHR$(1) will clear the screen. | ||
|
|
||
| Example 3 - define a special character with a "heart" (line 2) and print it 3 times (line 3): | ||
| 1 OPEN15,8,15 | ||
| 2 PRINT#15,"XTC"+CHR$(64)+CHR$(27)+CHR$(31)+CHR$(31)+CHR$(14)+CHR$(4)+CHR$(0)+CHR $(0) | ||
| 3 print#15,"XT1"+CHR$(8)+CHR$(8)+CHR$(8) | ||
| 4 CLOSE15 | ||
|
|
||
|
|
||
| Display About Message | ||
| ---------------------- | ||
|
|
||
| The XA command shows a small about message: | ||
|
|
||
| Example: | ||
|
|
||
| OPEN15,8,15,"XA" | ||
|
|
||
| Display Greetings & Credits | ||
| --------------------------- | ||
|
|
||
| The XG command shows the greetings and credits: | ||
|
|
||
| Example: | ||
|
|
||
| OPEN15,8,15,"XG" | ||
|
|
||
|
|
||
| Undocumented experimental feature | ||
| ---------------------------------- | ||
|
|
||
| The XX command is not documented. It might cause skynet to | ||
| link all computers together to play a game of global | ||
| thermonuclear war. | ||
|
|
||
| Maybe your C64 is not connected to skynet, so you'll give it a try. | ||
| Good luck! | ||
|
|
||
| Example: | ||
|
|
||
| OPEN15,8,15,"XX" | ||
|
|
||
|
|
||
| Setup LCD contrast (only for ST7036 based displays) | ||
| --------------------------------------------------- | ||
|
|
||
| The XC command changes the display contrast on a ST7036 based display | ||
| Valid contrast values go from 0 to 63. | ||
|
|
||
| Example: | ||
|
|
||
| OPEN15,8,15,"XC 40" | ||
|
|
||
| Note: | ||
| Once contrast is adjusted properly the setting can be saved with the XW command! | ||
|
|
||
|
|
||
|
|
||
| LCD Hardware | ||
| ============ | ||
|
|
||
| Every HD 44780 or ST7036 compatible displays (2x16 or 2x20 chars) should work | ||
| The display is accessed in 4-bit mode. | ||
|
|
||
| Different pinouts have to be used depending on the hardware variant | ||
| of the SD2IEC / MMC2IEC device: | ||
|
|
||
| sd2iec V1.4 by Shadowolf (sw1 variant) | ||
| MMC2IEC by Lars Pontoppidan (larsp variant) | ||
| ------------------------------------------- | ||
| (original design, also used by PCBs from Peter Sieg) | ||
|
|
||
| Display Atmega | ||
| RS PB0 | ||
| RW PB1 | ||
| E PB2 | ||
| DB4 PC4 | ||
| DB5 PC5 | ||
| DB6 PC6 | ||
| DB7 PC7 | ||
|
|
||
|
|
||
| sd2iec V1.6 by Shadowolf (sw2 variant) | ||
| -------------------------------------- | ||
| ATTENTION: I have not yet tested this pinout so it might be possible that it is not working. | ||
| At least it will be hard to solder the display to PB0,PB1 and PB3 if using a TQFP44 mcu. | ||
|
|
||
| Display Atmega | ||
| RS PB0 | ||
| RW PB1 | ||
| E PB3 | ||

||
| DB4 PC4 | ||
| DB5 PC5 | ||
| DB6 PC6 | ||
