In particular is interesting the method “Putc” because allows to print an ASCII character passing its decimal code.
This is the question: is supported Extended ASCII Table or not?
I tried to print the degrees char (°) but I can’t see it (the example above shows my attempt because 176 represents the extended ASCII table degrees char value). The display shows a minus char (-).
I haven’t looked at the code of the driver, or used it, but I would expect that you need to worry about the code that corresponds to the character, not the standard ASCII code… see something like http://shop.tuxgraphics.org/electronic/tuxgr_blue16x2_charset.png as an example of the standard character set. Edit: I see 176 is also the degrees symbol - time to dig into the driver code
Another question: is it possible to paint custom characters using the standard driver?
(I worked with a similar char display programming in C++ and I could paint custom characters by setting dots on and dots off manually) .
The controller also allows for 8 custom symbols/chars. I have a modified driver here someplace that I wrote to allow for setting and using the custom chars. I’ll clean it up and post it later on
