[原创] MM32F031开发板评测11：模拟点亮0.96寸OLED

ddllxxrr 2018-11-11 09:37 楼主

我本来手里有一个一半是黄色的一半是白色的OLED，我从网上买的。但我买回来之后就没有点亮过。
我十分伤心。我问了卖家，卖家也发了资料，我十分恼火，主要是这款OLED娘过可以变IIC通讯，还可以四线SPI，还可以三线SPI
我用烙铁焊了后边的跳线。把它变成IIC的驱动没有驱起来，我把它变成三线的还是黑乎乎一片。变成四线的还是。
泥马。。。。。。。老子不搞了行吧。。。。。。。。
就这样我一脚把这款屏打入了“冷宫“（盒子里）。一放就是三年。

   三年以后。。。。。。。。

   我参加了这个MM32F031的活动。我又把它给想起来了。看了一下是IIC的我就烦了（因为得加上拉。本人是个懒人，不想接上拉电阻来这），又跳回了三线SPI，就是没有那个发线的。本来想一举成功，泥马还是没有亮。

   我十分伤心，在我心里，它一定是坏了，或是卖家给我时就是坏的。万能的淘宝，黑心的卖家。。。。。。。

   本来这是上个星期的是，但我SPI软硬都驱动了SPI　２.２寸彩屏。给了我一定的自信能驱动这个OLED。

　　于是我忍痛割爱，花了１３块大洋。又从网上包邮一个回来。

　　全是白色的（我喜欢）。又是一个星期天了，又一个轮回。

　　早晨起来仍旧调程序。我先到网上收一下这个OLED的例程。本来想从卖家那里要资业，不过应是南方的卖家，没答理我，我想他不没有起来。

　　我从网上收了贴子都是５１的多我就下了一个改了起来。

初始化时要注意，同STM32不一样，的地方是那个GPIOA，和GPIOB的初始化部分，

RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA|RCC_AHBPeriph_GPIOB, ENABLE); //??PC,D,G????

而STM３２是ＡＨＢ２

我重新编译居然亮了，见照片

我又把以前的那块OLED管脚不动地插上，萌萌达，居然也亮了。到现在为止在我手上没有烧坏一块我买的OLED。
对一个单片机人来说这是今天双１１最大的礼物。
