Hi,

i just tried to connect a 20x4 Display to the I2C bus of my WRAP-Board, but
all i get is:
[...]
Server running in foreground
Listening for queries on 127.0.0.1:13666
screenlist_init()
driver_load( name="HD44780", filename="HD44780.so")
HD44780: I2C: Using device '/dev/i2c-0' and address 32 for a PCA9554(A)
HD44780: I2C: i2c write data 3 to address 32 failed: Function not implemented
HD44780: I2C: i2c write data 67 to address 32 failed: Function not implemented
HD44780: I2C: i2c write data 3 to address 32 failed: Function not implemented
[...]

The PCF8574 works when i use the pcf8574 kernel module.

Any ideas?

Christoph
