Hello,
I would like to be able to display things on the LCD screen during bootup time of the raspberry pi.
I have found this script:
https://learn.adafruit.com/drive-a-16x2 ... nit-script
but it happens that the message appears very late, at the end of the startup. Might be because it is a python script and cannot be run earlier.
Is their a way to display something on the LCD that would show up much earlier, at the beginning of the startup?
(I use a 16x2 LCD on a kit: https://www.adafruit.com/products/1110)

Re: display things on LCD during boot up
without compiling special modules for the kernel, not really. the system must 'come up' before you can run python since it uses the file system!

If there was a library written in shell script (bash or anything), would it be possible to get a significant progress compared to python?
