+ 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.

+ https://github.com/dhepper/font8x8/blob/master/font8x8_basic.h

+ uint8_t trans[8];
+ for (int w = 0; w < 8; w++) {
+ trans[w] = 0x00;

+ }
+ }
+
