Hi, I'm trying to use the SPI BitWizard display with keypad,

http://www.bitwizard.nl/wiki/index.php/ ... erface#SPI
All I got from it after many tests is the initial message

"SPI_rpi_ui 1.6
A: 94"

For instance, the command to clear the lcd,

bw_tool -I -a 94 -r 16 -v 0

reports

can't open device: No such file or directory
Aborted

I tried to write to SPI using Wiring, no success.

Do you have that shield ? Any suggestion would be appreciated !

Thanks

It seems the SPI driver isn't loaded. Try "sudo insmod spi-bcm2708", and then run your command.
