LCD raspberry pi accents

Post by slorg1 »

Hi,

I purchased the "Adafruit 16x2 Character LCD + Keypad for Raspberry Pi" (https://learn.adafruit.com/adafruit-16x ... i/overview)
I have been able to use it no problem. It is really nice.

Recently, I tried to use it with internationalization and it does not seem to handle accents out of the box. I have looked for answers on the internet and I could not find anything that worked with this model. I have read that some models allow drawing your own characters but it is not clear to me how.

Could you please point me in the right direction or share some code to help?

Thank you.

The datasheet for the display is here. There is no provision for custom fonts.

Hi,

Thank you for your answer.

On page 17, I seem to see accented characters. I am not looking for something too custom.

I tested the table and it seems I have ROM code: A00, do you know how I could get the ROM code: A02? (or flash the ROM is something like that is possible).

I determined that by writing:
0b11100000 to the screen and got the alpha symbol.

Thank you.

ROM A02 is a different chip.

I'm sorry, but I really don't know. The datasheet for the driver chip is here
https://www.adafruit.com/datasheets/HD44780.pdf
It has some part numbers on page 2 - maybe that will help you.
