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
For instance, the command to clear the lcd,
bw_tool -I -a 94 -r 16 -v 0
can't open device: No such file or directory
I tried to write to SPI using Wiring, no success.
Do you have that shield ? Any suggestion would be appreciated !
