Constant: font8x8_basic_tr
|
||||
Contains an 90 digree transposed 8x8 font map for unicode points
|
||||
U+0000 - U+007F (basic latin)
|
||||
|
||||
To make it easy to use with SSD1306's GDDRAM mapping and API,
|
||||
this constant is an 90 degree transposed.
|
||||
The original version written by Marcel Sondaar is availble at:
|
||||
https://github.com/dhepper/font8x8/blob/master/font8x8_basic.h
|
||||
Conversion is done via following procedure:
|
||||
|
||||
for (int code = 0; code < 128; code++) {
|
||||
uint8_t trans[8];
|
||||
for (int w = 0; w < 8; w++) {
|
||||
trans[w] = 0x00;
|
||||
for (int b = 0; b < 8; b++) {
|
||||
trans[w] |= ((font8x8_basic[code][b] & (1 << w)) >> w) << b;
|
||||
}
|
||||
}
|
||||
|
||||
for (int w = 0; w < 8; w++) {
|
||||
if (w == 0) { printf(" { "); }
|
||||
printf("0x%.2X", trans[w]);
|
||||
if (w < 7) { printf(", "); }
|
||||
if (w == 7) { printf(" }, // U+00%.2X (%c)\n", code, code); }
|

}
