This demo is based on the GD32E230C-EVAL-V1.1 board, it provides a description
|
|
of how to use the SPI to drive tft lcd.
|
|
|
|
After system start-up, all the leds are turned on and then turned off for test.
|
|
After that, the lcd panel is cleared to BLUE and four tests which are Font, Number,
|
|
Draw and Color will be carried out. In Font test, some English and Chinese characters
|
|
will be displayed on the lcd screen. In Number test, number 0 to 9 will be shown on
|
|
the lcd screen. In Draw test, different shapes will be shown. At last, different kinds
|
|
