M5StickC Plusで画面のちらつき(フリッカー)を抑止する方法のサンプルコード | |
MicroPython版 | |
(Arduinoの場合はTFT_eSpriteを使うと良いらしい) | |
動作環境 | |
UIFlow_StickC_Plus v1.11.1 | |
sys.version = '3.4.0' | |
sys.implementation.version = (1, 12, 0) | |
以下の処理を行うと sprite の表示位置/サイズがおかしくなる | |
* lcd.setRotation() を使用 | |
* lcd.orient() を使用 | |
* lcd.sprite_delete() してから lcd.sprite_create() する (spriteの再生成) | |
そのため縦表示の状態で表示要素を回転して表示している | |
''' | |
lcd.clear() | |
wifiCfg.autoConnect(lcdShow=True) | |
ntptime.client(host='pool.ntp.org', timezone=9) | |
screen_w, screen_h = lcd.screensize() | |
lcd.sprite_create(screen_w, screen_h, lcd.SPRITE_8BIT) | |
lcd.font(lcd.FONT_DejaVu24, fixedwidth=True, color=lcd.WHITE, rotate=270) | |
font_w, font_h = lcd.fontSize() | |
text_w = lcd.textWidth('00:00:00') | |
position_x = int(screen_w / 2 - font_w / 2) | |
position_y = min(int(screen_h / 2 + text_w / 2), screen_h - font_h) | |
while True: | |
lcd.sprite_select() | |
lcd.fillRect(0, 0, screen_w, screen_h, lcd.BLACK) | |
_, _, _, hour, minute, second, *_ = utime.localtime() | |
lcd.text(position_x, position_y, '{:02d}:{:02d}:{:02d}'.format(hour, minute, second)) | |
lcd.sprite_deselect() | |
lcd.sprite_show(0, 0) | |
utime.sleep(0.5) |
