OLED 不能正常运行

赵大鳖

最近在学习OLED的SPI4线传输
主控：STM32F103C8T6
OLED：1.3寸OLED，7管脚（GND，VCC，CLK，MOSI，RES，DC，CS）；

目前情况：改写原子哥mini板程序，不能运行。

                                                                                            图一
接线方式：
CLK ------>A5 SPI1_CLK
MOSI----->A7 SPI1_MOSI
RES ------>A1
DC ------->A6 SPI1_MISO
CS ------->A4 SPI_NSS

这是OLED_INIT();

本人STM32还未入门，可能有非常多的低级错误，希望各位大神指出。不胜感激！另Q523886078，随时可以Q我，讨论。
请各位大神指教！

你参考哪个版本的mini板 例程  参考这个改改   把相应的IO改改就行了

Admin

是的。改动仅仅是io口的。
还有，我们用的模拟spi方式，你用的硬件spi方式，这个你要熟悉stm32 spi才行。

赵大鳖

恩，今天已经把模拟SPI控制OLED搞懂了。现在硬件OLED有问题了：
OLED连接方式
OLED                  STM32
CLK --------------->SCK
MOSI-------------->MOSI
RES --------------->A3
DC ---------------->MISO
CS ---------------->NSS

现在板子不能显示。不知道是驱动SPI的问题还是OLED的读写问题？
