Added support for graphisc LCD displays from Nokia 3310,5110,5150,6110 or similar GSM phones. This firmware is BETA test version, and may have some bugs. Modifications for LCD use (only boards older than Rev.C !): 1. Cut track from pin 1 of VS1001 to pin 5 of ATmega (DREQ sygnal). 2. Add in series (on cutting place) 10k (or 4k7) resistor. 3. Add 100nF capacitor from pin 4 of ATmega (RESET signal) to ground. 4. Add a 1uF or 2.2uF thantalum capacitor, - to GND, and + to pin 7 of LCD MODULE. 5. Connect the display with following scheme: LCD module <-> yampp7 (pin 1) VDD - VCC* (pin 2) SCLK - SCK (pin 3 of ATmega) (pin 3) SDIN - MOSI (pin 1 of ATmega) (pin 4) D/C - DREQ (direct to pin 5 of ATmega) (pin 5) SCE - SS (pin 44 of ATmega) (pin 6) GND - GND (pin 7) VOUT - 1 or 2.2uF capacitor to GND (pin 8) RES - RESET (pin 4 of ATmega) Looking at the Nokia 3310 display back side, connector up, counting from left to right - the pins is numbered from 1 to 8. Check images on http://www.republika.pl/romek_by/y7photo.html for mounting example. If you need any backlight for LCD, you may use pin 40 of ATmega instead of LED output, and change "#define BACKLIGHT_TIME" in Constants.h file to non-zero value On this case you have additional position in menu: Backlight Mode. Three modes possible: Permanent OFF, Permanent ON, Auto mode. +Keyboard layout is changed. Now is: 1. While playing song BUTTON_1 BUTTON_2 BUTTON_3 BUTTON_4 ShortPress: PLAY/PAUSE STOP NEXT PREV LongPress: F.FWD MENU VOL UP VOL DOWN 2. On Stop BUTTON_1 BUTTON_2 BUTTON_3 BUTTON_4 ShortPress: PLAY STOP(NONE) MBASS RANDOM LongPress: PWR.OFF MENU Autolock ON/OFF LCD Contrast -------------------------------------------------------------------------------- v1.13 - 2002-10-09 some falstarts in version 1.12 :((( *fixed accidentally bootloader entering during keyboard lock/unlock *fixed accidentally song change after keyboard unlocking +added beeps for manual lock/unlock confirmation - high beep = ON, low = OFF. Beeps may be turn off by commenting LOCK_BEEP definition in "Constants.h" file. +added option for autolock ON/OFF during normal operation. If you enable autolock function in "Constants.h", you may turn ON or OFF autolock functionality by pressing VOL_UP key for long time during STOP condition. Status is confirmed by beep - like MegaBass or Random status change. See updated keys layout. -------------------------------------------------------------------------------- v1.12 - 2002-10-07 +added keyboard locking functions with autolock. For keyboard lock/unlock press and hold two top buttons (BUTTON 3 and BUTTON 4) for 1 second during play state. Lock and unlock be confirmed by led flashing until you release these keys. If you enable automatic lock function by setting AUTOLOCK_TIME to non-zero value (in Constants.h file), your keyboard be automatically locked after defined time of playing, counted from last key touch. Autolock moment is confirmed too by LED flashing. Default is enabled after one minute. -------------------------------------------------------------------------------- v1.11 - 2002-10-04 +added card removing checking during pause and stop mode +code speed-up and cleaning +added configurable CF standby time (in Constants.h file) TIP: If player cant startup after card changing (genetates series of beeps and automatic power-off) - remove card, startup yampp, and insert card back during the beep series. -------------------------------------------------------------------------------- v1.10 - 2002-09-27 + added true random function (max 1024 songs in playlist) -------------------------------------------------------------------------------- v1.00 - 2002-09-23 First public release. Features : - Card present checking, if no card present or card removed - yampp go to sleep mode - Automatic card formatting if card don't have YADL format. Insert new card and power up yampp for card format. - Additionally LED output on PB0 (need* mount LED and 2.2K resistor in series, from pin 40 of ATmega103 to ground) - Wakeup from sleep need press and hold "Play" key for two seconds - Beep during playlist change, playlist have different tone from other. - Delay in keypress checking for avoid accidental key pressing. - FastForward, Random, Loudness and Repeat functions. - All functions is handled by 4 keys, layout is depending on playing state. - Trap for vs1001 lockup if MP3 has garbage - Manual power off -> longpress STOP key in Stop mode. - Auto power of from pause state after 30 minutes - Battery level monitoring (default disabled). This function need* small yampp board modification by adding two resistors. One 33k from PB3 (pin 43 of ATmega) to ground, and second 51k from the same PB3 to VCC. After this change you may enable "#define BATTERY_TEST" definition in Constants.h file. Battery low level is signalised by LED blink during playing, and short beep in 2 minute interval. After 15 minutes of playing with low battery level, yampp automatically go to sleep mode. - Battery charging indicator (only LI-ION cells). This function need* one more small board modification. You may connect pin 8 of MAX1811 (CHG output) to pin 26 of ATmega (OC1B line). If you do this, and connect USB cable in STOP condition, the LED switch blink parameters to long on / short off until battery is near end of charge. NOTE: At this point battery is charged about 80% of full capacity. To full charge you need about 15 minutes additional charging time. Automatic power off be disabled too, for avoid shutdown FTDI chip and disconect power from some models of USB hubs. (*) "C" revision of yampp-7 board (future) not need these modifications. If you have "B" version of yampp-7 board you may find some modifications details pictures in "yampp7_modif.zip" file(battery charge indication connection is not shown). ---------------------- Keyboard Layout: 1. While playing song BUTTON_1 BUTTON_2 BUTTON_3 BUTTON_4 ShortPress: PLAY/PAUSE STOP NEXT PREV LongPress: F.FWD NEXT_PL VOL UP VOL DOWN 2. On Stop BUTTON_1 BUTTON_2 BUTTON_3 BUTTON_4 ShortPress: PLAY STOP(NONE) MBASS RANDOM LongPress: REPEAT PWR.OFF Autolock ON/OFF No function ---------------------- MegaBass, Loudness and Autolock functions ON/OFF is confirmed by beeps: Low beep = OFF, High Beep = ON Random mode is confirmed by count of beeps (from 1 to 4). 1 beep - Play single playlist and stop at end, 2 beeps - Play all playlists, 3 beeps - Repeat playlist, 4 beeps - Repeat one song.
