这次使用PYB Nano驱动0.96寸OLED显示屏，此次参考了国外网友的例程，OLED可以使用SPI或者I2C均可。
【1】硬件连接：
这里以SPI连接方式为例，使用PYB Nano的SPI1：

【2】程序源码：
库文件：SSD1306 import pyb from ssd1306 import SSD1306 # SPI display = SSD1306(pinout={'dc': 'Y9', 'res': 'Y10'}, height=64, external_vcc=False) # I2C connected to Y9, Y10 (I2C bus 2) # display = SSD1306(pinout={'sda': 'Y10', # 'scl': 'Y9'}, # height=64, # external_vcc=False) led_red = pyb.LED(1) led_red.off() try: display.poweron() display.init_display() display.draw_text(1,1,'PYB Nano OLED Test',size=1,space=1) display.draw_text(1,10,'Hello MicroPython!',size=1,space=1) # Write display buffer display.display() pyb.delay(10000) x = 0 y = 0 direction_x = True direction_y = True while True: # Clear the previous lines prev_x = x prev_y = y # Move bars x += (1 if direction_x else -1) y += (1 if direction_y else -1) # Bounce back, if required if x == 128: direction_x = False x = 126 elif x == -1: direction_x = True x = 1 if y == 64: direction_y = False y = 63 elif y == -1: direction_y = True y = 1 # Draw new lines for i in range(64): display.set_pixel(prev_x, i, False) display.set_pixel(x, i, True) for i in range(128): display.set_pixel(i, prev_y, False) display.set_pixel(i, y, True) # Make sure the corners are active display.set_pixel(0, 0, True) display.set_pixel(127, 0, True) display.set_pixel(0, 63, True) display.set_pixel(127, 63, True) # Write display buffer display.display() except Exception as ex: led_red.on() print('Unexpected error: {0}'.format(ex)) display.poweroff()
