Other Parts Discussed in Thread: TMS320VC5505

I am using ezdsp TMS320Vc5505 USB Stick and like to interface 16*2 LCD for quick display of results.

 

I have used following websites to manually set things up for 4 bit LCD mode. just want to ask is there any built in library for setting things up

    Hi Moinuddin,

    Check out the Chip Support Library for APIs and examples that configure the DSP and its peripherals mostly for off-chip communication.

    The LCD peripheral supports HD44780U mode (see here), but with the VC5505 eZdsp, a couple of the LCD pins (LCD_RW_WRB & LCD_RS) are not routed from the DSP to the edge connector... You'd be better off with the C5515 eZdsp, which has all the signals routed.

    You could probably get that LCD to work with just GPIOs, but it might be easier to choose an I2C or SPI LCD controller to interface to the LCD.

    In the C5515 eZdsp, we use a 96x16 pix LCD with built-in I2C controller.

    The C5515, C5505, and VC5505 are all very similar DSPs.

    Hope this helps,
    Mark
