LK162-12

[3space]

HI,
I'm using a PIC16F877A to communicate with my LCD. I can send text to the LCD, however, when I try sending commands (e.g. clear display) nothing happens. Here is what i have for writing to the display:

movlw 0x50 ;LK162-12 address (write)
banksel SSPBUF
movwf SSPBUF

movlw 0xFE ;FE=command prefix, 0x58 (clear display)
banksel SSPBUF
movwf SSPBUF
movlw b'01011000'
banksel SSPBUF
movwf SSPBUF

I have ommitted the I2C initialization code. Can anyone tell me if there is something wrong with the way I'm sending the command.

Thanks,
Mark

Hi,

If you email me at support@matrixorbital.com, I will send you a sample I2C C code you can use. There is also a guide for developing or using I2C with our displays at http://www.lcdforums.com/forums/viewtopic.php?t=910.

Best Regards,
