RK3568笔记四十二：OLED 屏幕驱动(模拟I2C)

若该文为原创文章，转载请注明原文出处。

本篇记录使用GPIO模拟I2C驱动OLED屏幕，显示界面效果如下。

主要流程是，修改设备树，使用普通IO口，驱动模拟I2C方式，应用程直接传输数据控制。

1、修改设备

2、编写I2C驱动

3、编写应用程序

一、OLED介绍

SSD1306是一款带控制器的用于OLED点阵图形显示系统的单片CMOS OLED/PLED驱动器。

手上的屏幕使用的是I2C方式驱动，I2C总线包含从机地址位 SA0，由数据信号线（SDA）和时钟信号线（SCL）组成。SDA和SCL线都必须接上拉电阻。

写入时序
IIC写入时序如下所示：

1、主机先发起开始（START）信号，然后发送1byte首字节，包括从机地址(7位)和读写数据位(1位，最低位，0为写模式)，驱动器识别从机地址为本机地址之后，将会发出应答信号(ACK) 。（首字节组成如下图所示）
2、主机收到从机（驱动器）的应答信号之后，随后传输1byte控制字节。一个控制字节主要由
CO 和 D/C# 位后面再加上六个0组成的。（控制字节组成如下图所示）
如果Co为0，后面传输的信息就只包含数据字节。
D/C# 位决定了下个数据字节是作为命令还是数据。D/C# 为0时，下一个数据被视为命令；DC# 为1时，下一个数据被视为显示数据，存储到GDDRAM中。
3、收到控制字节ACK信号之后，传输要写入的数据字节。
4、传输完毕之后主机发出结束（STOP）信号。

二、原理图

SCL: GPIO3_PC4

SDA: GPIO3_PC5

三、创建设备节点

1、设备树节点

修改/home/alientek/rk3568_linux_sdk/kernel/arch/arm64/boot/dts/rockchip/目录下的rk3568-atk-evb1-ddr4-v10.dtsi文件，添加gpios节点，并在gpios下创建两个子节点sda和scl.

gpios {
  compatible = "gpio-i2c-test";
  pinctrl-names = "default";
  status = "okay";
  sda {
    compatible = "sda-test";
    pinctrl-0 = <&pinctrl_sda>;
    gpios-sda = <&gpio3 RK_PC5 GPIO_ACTIVE_HIGH>;
    status = "okay";
  };
  
  scl {
    compatible = "scl-test";
    pinctrl-0 = <&pinctrl_scl>;
    gpios-scl = <&gpio3 RK_PC4 GPIO_ACTIVE_HIGH>;
    status = "okay";
  };
};

2、创建设备的 pinctrl 节点

修改/home/alientek/rk3568_linux_sdk/kernel/arch/arm64/boot/dts/rockchip/目录下的rk3568-pinctrl.dtsi文件，在最后面增加节点

sda-gpio {
    pinctrl_sda: sda-gpio-ctrl {
        rockchip,pins = <3 RK_PC5 RK_FUNC_GPIO &pcfg_pull_none>;
    };
};
 
scl-gpio {
    pinctrl_scl: scl-gpio-ctrl {
        rockchip,pins = <3 RK_PC4 RK_FUNC_GPIO &pcfg_pull_none>;
    };

四、驱动编写

1、drv_oled.c

/*
gpios {
  compatible = "gpio-i2c-test";
  pinctrl-names = "default";
  status = "okay";
  sda {
    compatible = "sda-test";
    pinctrl-0 = <&pinctrl_sda>;
    gpios-sda = <&gpio3 RK_PC5 GPIO_ACTIVE_HIGH>;
    status = "okay";
  };
  
  scl {
    compatible = "scl-test";
    pinctrl-0 = <&pinctrl_scl>;
    gpios-scl = <&gpio3 RK_PC4 GPIO_ACTIVE_HIGH>;
    status = "okay";
  };
};

sda-gpio {
    pinctrl_sda: sda-gpio-ctrl {
        rockchip,pins = <3 RK_PC5 RK_FUNC_GPIO &pcfg_pull_none>;
    };
};
 
scl-gpio {
    pinctrl_scl: scl-gpio-ctrl {
        rockchip,pins = <3 RK_PC4 RK_FUNC_GPIO &pcfg_pull_none>;
    };
};

程序主要是写函数

通过用户空间传过来的值模拟写数据或写命令操作操作，启动I2C使用模拟方式。

2、makefile

KERNELDIR := /home/alientek/rk3568_linux_sdk/kernel
ARCH=arm64
CROSS_COMPILE=/opt/atk-dlrk356x-toolchain/usr/bin/aarch64-buildroot-linux-gnu-

export  ARCH  CROSS_COMPILE

CURRENT_PATH := $(shell pwd)
obj-m := drv_oled.o

build: kernel_modules

kernel_modules:
	$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) modules
clean:
	$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) clean

编译生成ko文件，拷贝到开发板上。

五、应用程序

应用程序有4个文件，font.h（字库），main.c（主程序），oled.c（oled驱动），oled.h（头文件）

程序仅供参考：

1、main.c

#include "stdio.h"
#include "unistd.h"
#include "sys/types.h"
#include "sys/stat.h"
#include "fcntl.h"
#include "stdlib.h"
#include "string.h"


#include "oled.h"


int oled_i2c_open(char *dev)
{
  int fd = -1;

  if (dev == NULL)
  {
    return fd;
  }

  fd = open(dev, O_RDWR);

  if (fd < 0)
  {
    printf("can't open oled drv\n");
    return fd;
  }

  return fd;
}



int main(int argc, char *argv[])
{
  int fd;
  int i = 0;
  char cmd[32];
  
  fd = oled_i2c_open("/dev/oled");
  SetOledFd(fd);

  initOLED();
  
  formatScreen(0x00);//清屏

  OLED_ShowString(0, 0, "hello world", 16);

  while(1)
  {
    memset(cmd, 0, 32);
    i++;
    sprintf(cmd, "%04d", i);
    OLED_ShowString(0, 2, cmd, 16);
    
    sleep(1);
  }

  close(fd);
  
  return 0;
}

功能是显示 “hello world"，每秒累加1.
