OLED屏幕和Rpi

为了之后做甲醛探测买了一块显示频:SSD1331。结果买回来不会接线。下面这个链接非常好用，最赞的是那个网页上代码SSD1331.py， 基本改一下针脚，就妥妥的了。注意，这次的针脚不是物理数针啦:

不过介于他用的还是一代。我这里就记录一下二代40针的接线方法。

pin VCC -> pin1 3v3

pin GND -> pin 6 ground

pin NC is not connected to any pin on Rpi

pin DIN -> pin 19 SPI_MOSI

pin CLK -> pin 23 SPI_CLK

pin CS -> pin 11 GPIO 17

pin D/C -> pin 13 GPIO 27

pin RES -> pin 15 GPIO 22

import SSD1331
import datetime
import time
import math

SSD1331_PIN_CS  = 17
SSD1331_PIN_DC  = 27
SSD1331_PIN_RST = 22

if __name__ == '__main__':
device = SSD1331.SSD1331(SSD1331_PIN_DC, SSD1331_PIN_RST, SSD1331_PIN_CS)
try:
device.EnableDisplay(True)
device.Clear()
today_play = "Have fun there!"
while True:

device.DrawString(8, 35, today_play, SSD1331.COLOR_PURPLE)

time.sleep(0.5)
finally:
device.EnableDisplay(False)
device.Remove()

图丑? 对，其实主要为了放那个猫…
