[lcd4linux] problem with i2c connected LCD display

[paul k. <pau...@xs...>]

Hi,

Is there anyone using lcd4linux in combination with an HD44780 based LCD 
display connect via i2c bus?

I am using a PCF8574 i2c 8-bits IO extender to connect the LCD display.
The i2c is detect by i2cdetect on device id 26 (hex)

in lcd4linux.conf I have the following display definition:

Display HD44780-I2C {
        Driver 'HD44780'
        Bus 'i2c'
        Port '/dev/i2c-0'
        Device '0x26'
        UseBusy '1'
        Bits '4'
        Size '16x2'
        Wire {
                 RW 'DB4'
                 RS 'DB5'
                 ENABLE 'DB6'
                 GPO 'GND'
        }
}

But when I run lcd4linux I get the following output:

Version 0.9.11 starting
lcd4linux.c: initializing driver HD44780-I2C {
lcd_init(HD44780-I2C {) failed: no such display

I tried different device id's (26, 38 ) to no effect. What is it I am 
missing here?

Any help/suggestions appreciated

Paul
