Re: [lcd4linux] Problem with lcd4linux 0.10.0 / framebuffer

[Julien B. <Dha...@ho...>]

Hi Michael,

Never mind my last e-mail, I fond the file and modified it. Sorry about
that.
The GKL still doesn't work. Get the same error message. However, setting it
up as an LCD4041 seems to work.
One last question: I think the "clear" function does not work. I will
attempt to fix it but I must tell you that my knowledge of C is like
vaporware LOL

drv_generic_serial_write("\376\130", 2); --> the \376\130 these are decimal
number equivalent to ascii characters you send to the LCD right? Sequence
"command + command number".

Thanks for your patience,

Julien
