  1. SDK&UI&LCM&FM Presentation 報告人: 侯欽堅

  2. Outline • SDK Structure & Code Flow • LCM SPEC & Hardware • LCM Code • FM SPEC & Hardware • FM Code • UI Hardware • UI Code • API Structure & Code Flow

  3. SDK Structure & Code Flow • SDK : Software Development Kit • User’s Development : Song , UI , LCM , FM Module , Lyrics… • \RAM_user\example2\Lcd_controller2.c, funentry.c, i2c.c, song.c, fm_tea5767.c, gpio.c, lrc_parser.c • 與Kernel的連接方式 : a. Customize Function Entry: api_bCustomizeFunEntry() b. APIs

  4. api_bCustomizeFunEntry() • To process the event from the Kernel A. EVENT_QUARTER_SECOND: LCM Display , Timer B. EVENT_LOOP_EPILOG : Song events, Key process C. EVENT_USB_STATUS_CHANGE : USB Status show D. USB_CABLE_IN : Cable in process E. USB_CABLE_OUT : Cable out process F. SYS_INIT_PROLOG : LCD & Radio initial G. SYS_INIT_EPILOG : GUI & Song & Display initial

  5. Example Code Flow • funentry.c : api_bCustomizeFunEntry() • Lcd_controller2.c : LCM Basic process • i2c.c : I2C Driver • fm_tea5767.c : FM Driver • gpio.c : Button basic process • song.c : LCD Display , UI flow control • lrc_parser.c : Lyrics show

  11. FM SPEC & Hardware • I2C Protocol • FM Register

  12. I2C Protocol • SDA : Serial Data line • SCL : Serial Clock line • Every device has its own unique address • Start • Stop • Send BYTE • Receive BYTE

  13. I2C : Start & Stop

  14. I2C : Send BYTE • Once the start condition has been sent, a byte can be transmitted by the MASTER to the SLAVE. • This first byte after a start condition will identify the slave on the bus (address) and will select the mode of operation. • ACK

  15. I2C : Receive BYTE • All the master has to do is generate a rising edge on the SCL line (2), read the level on SDA (3) and generate a falling edge on the SCL line (4). The slave will not change the data during the time that SCL is high.
