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];
|
||||
