Raspberry Pi でOLEDにmpd 曲名を追加(Python3 ver.) 曲名full test ver.

長い曲名の後半が表示されてない問題への、とりえずの対応版です。

長い場合は、次行に表示するように試みる。

# Raspberry Pi pin configuration:

RST = 24

# Note the following are only used with SPI:

DC = 23

SPI_PORT = 0

SPI_DEVICE = 0

# Note the following are only used with SPI:

# DC = 'P9_15'

# SPI_PORT = 1

# 128x32 display with hardware I2C:

##disp = Adafruit_SSD1306.SSD1306_128_32(rst=RST)

# 128x64 display with hardware I2C:

# disp = Adafruit_SSD1306.SSD1306_128_64(rst=RST)

# Note you can change the I2C address by passing an i2c_address parameter like:

disp = Adafruit_SSD1306.SSD1306_128_64(rst=RST, i2c_address=0x3C)

# Alternatively you can specify an explicit I2C bus number, for example

# with the 128x32 display you would use:

# disp = Adafruit_SSD1306.SSD1306_128_32(rst=RST, i2c_bus=2)

# 128x32 display with hardware SPI:

# disp = Adafruit_SSD1306.SSD1306_128_32(rst=RST, dc=DC, spi=SPI.SpiDev(SPI_PORT, SPI_DEVICE, max_speed_hz=8000000))

# 128x64 display with hardware SPI:

# disp = Adafruit_SSD1306.SSD1306_128_64(rst=RST, dc=DC, spi=SPI.SpiDev(SPI_PORT, SPI_DEVICE, max_speed_hz=8000000))

# Alternatively you can specify a software SPI implementation by providing

# digital GPIO pin numbers for all the required display pins.  For example

# on a Raspberry Pi with the 128x32 display you might use:

# disp = Adafruit_SSD1306.SSD1306_128_32(rst=RST, dc=DC, sclk=18, din=25, cs=22)
