oled.fill(0) oled.blit(fbuf,0,0) oled.show()delfbuf 调用代码 bad_apple_oled = BadAppleOled() bad_apple_oled.init_oled() bad_apple_oled.show_pic() 最终结果如下 代码解释: 首先将文件读取成二进制 with open(show_pbm, 'rb')
rang_us = utime.ticks_diff(end_us,start_us)/10000dist = rang_us*340/2print("dist is: %0.2f CM"% dist) 但是,上面代码的输出都是通过print输出的,不太灵性。之前我们有做过连接OLED,这里我们可以把OLED也用起来。 效果如下,我们还可以把之前的红绿灯也插上去。红灯停,绿灯行。哈哈。
