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

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

FM SPEC & Hardware

I2C Protocol FM Register

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

I2C : Start & Stop

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.

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.

FM SPEC

0x80, 0x00, 0x00, 0x40, 0x00
