How to set a charactermap?

Hi Bart,

   What Stellaris Kit are you using? Stellarisware for kits that have an OLED, has a graphics sample program. Reviewing the graphics sample program would help.

   If you need to display graphics at your OLED, the OLED bitmap tool attachment in this thread below might help. I have used this to display graphics at the OLED of my LM3S6965 Evaluation Kit successfully.

Hi Markel,

I'm using a Stellaris LM4F120 Eval board.

Using this approach would only give you the ability to display static data (premade with that sample program)?
So displaying realtime info (like a clock or sensordata) would not work?

In Python I made a character map like this:

charmap = {
        ' ':[0x00, 0x00, 0x00, 0x00, 0x00],
        '!':[0x00, 0x00, 0x5F, 0x00, 0x00],
        '"':[0x00, 0x07, 0x00, 0x07, 0x00],
        ...
}

with functions to draw the character:

def oled_drawChar(c):
        charm = dict(charmap)
        for k in range(0,5):
                bus.write_byte_data(a, 0x40, charm[c][k])
        bus.write_byte_data(a, 0x40, 0x00)

def oled_write(word):
        for c in word:
                oled_drawChar(c)

With this I could give realtime info on my oled display (clock, ip,...) but on my Stellaris I'm already stuck at translating the Python Dictionary to C++...
How could I tackle this so that I can keep the same (more or less) approach in displaying characters?

With kind regards,

Bart

Hi Markel,

Ok, I'll have a look at it.

Thx!

Also aBUGSworstnightmare his API is of good help it seems!
