To create a bitmap for Nokia5110 LCD and SSD1306 OLED
|
||
|
|
Jonathan Valvano, 11/7/2020
|
||
|
|
1) Create a bitmap file. Since the Nokia5110 and SSD1306 are black and white,
|
||
|
|
it will look best to have a white image on a black background.
|
||
|
|
Also consider framing the image with a black border of at least
|
||
|
|
one pixel on all four sides so the image can be slid without
|
||
|
|
smearing.
|
||
|
|
4-bit color, 16-color bmp
|
||
|
|
Nokia: width less than or equal to 84 pixels
|
||
|
|
Nokia: height less than or equal 48 pixels
|
||
|
|
SSD1306 width less than or equal to 128 pixels
|
||
|
|
SSD1306 height less than or equal 64 pixels
|
||
|
|
width must be even
|
||
|
|
save the image as a 16-color bmp file
|
||
|
|
store in same directory as BmpConvert.exe
|
||
|
|
2) Execute BmpConvert.exe
|
||
|
|
Type the image name
|
||
|
|
E.g., if the file is ti.bmp, then type ti
|
||
|
|
3) Open the corresponding txt file, select all, copy
|
||
|
|
4) Open Code Composer Studio compiler
|
||
|
|
Paste new image as a data constant
|
||
|
|
(Optional) Change "unsigned char" to "uint8_t"
|
||
|
|
5) If the image is full size, print it in the top left corner with the following:
|
||
|
|
a) Clear the RAM image buffer
|
||
|
|
Nokia5110_ClearBuffer();
|
||
|
|
or SSD1306_ClearBuffer();
|
||
|
|
b) Put the bitmap in the RAM image buffer
|
||
|
|
Nokia5110_PrintBMP(0, 0, ti, 0);
|
||
|
|
SSD1306_DrawBMP(0, 0, ti, 0);
|
||
|
|
(Optional) The fourth parameter 0 makes any non-zero pixel 'on'.
|
||
|
|
Depending on how colors are used, this might look bad in black
|
||
|
|
and white. Increase this parameter up to 14 to reject more
|
||
|
|
colors from turning their corresponding pixels 'on'.
|
||
|
|
c) Display the RAM image buffer to the entire screen
|
||
|
|
Nokia5110_DisplayBuffer();
|
||
|
|
or SSD1306_OutBuffer();
