pt2258+16f877 how can i use for 5.1 volume control ?
hi , everyone. i am noobie in there. im working learn pic.
i wanna build 5.1 ch volume control with pic16f877 and pt2258.and next time lcd and smps control , ir control ....music system...
pt series chip is using i2c protocol.
this pt 2258 datasheet:
http://www.datasheetcatalog.net/data...2/PT2258.shtml
i am training something. this is my code:
Config XT_OSC , WDT_OFF , PWRTE_ON , BODEN_OFF , LVP_OFF , WRTE_ON , CP_OFF , DEBUG_OFF
Device 16F877
XTAL 4
ADCON1=7
Symbol SCL=PORTC.3
Symbol SDA=PORTC.4
Declare I2C_SLOW_BUS On
pause 100
GoSub RST

If PORTA.0=1 Then COK
If PORTA.1=1 Then AZ
If PORTA.2=1 Then SUS
If PORTA.3=1 Then GoSub RST
