应用层使用I2c-1驱动 0.96寸oled

Duo
1

1、查看iic的设备节点
在板子上查看iic设备节点

ls /dev/i2c-*

选用i2c-1做这个实验
{9D7DB257-C62F-4245-8995-0CB48F595FEC}
对应引脚
1
使用duo-pinmux工具将GP10和GP11设置为IIC模式，可以用下

duo-pinmux -w GP10/IIC1_SDA
duo-pinmux -w GP11/IIC1_SCL

使用i2c_tools工具可以查看接上的设备地址为十六进制
因为将设备挂在i2-1

使用指令可以查看接上没有
i2cdetect -y -r 1

2、编写应用层程序

2.1、oled.h

#endif

2.4 oled_app.c
主要在这里面

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>
#include <oled.h>

/* 
应用层使用i2c控制oled
*/

int fd;
//写数据

int main(int argc, char **argv)
{
	if(argc < 2)
	{
		printf("Usage: %s 字符串\n", argv[0]);
		return -1;
	}
	fd = open("/dev/i2c-1", O_RDWR);//打开设备节点 可读可写
	if(fd < 0)
	{
		perror("open error");
		return -1;
	}
	OLED_Init();
	OLED_ColorTurn(0);//0正常显示，1 反色显示
    OLED_DisplayTurn(0);//0正常显示 1 屏幕翻转显示
	OLED_Clear();
	sleep(1);

	OLED_ShowString(0,0,argv[1],16);
	OLED_Refresh();
	close(fd);
	return 0;
}

3、将oled_app.c程序编译
编写Makefile

TOOLCHAIN_PREFIX为你的交叉编译器绝对路径

TARGET=oled_app

TOOLCHAIN_PREFIX= /home/milk/duo-examples/duo-sdk/riscv64-linux-musl-x86_64/bin/riscv64-unknown-linux-musl-

CC = $(TOOLCHAIN_PREFIX)gcc

CFLAGS += -I$(SYSROOT)/usr/include
CFLAGS += -I ./

LDFLAGS += -L$(SYSROOT)/lib
LDFLAGS += -L$(SYSROOT)/usr/lib

SOURCE = $(wildcard *.c)
OBJS = $(patsubst %.c,%.o,$(SOURCE))

$(TARGET): $(OBJS)
	$(CC) -o $@ $(OBJS) $(LDFLAGS)

%.o: %.c
	$(CC) $(CFLAGS) -o $@ -c $<

.PHONY: clean
clean:
	@rm *.o -rf
	@rm $(OBJS) -rf
	@rm $(TARGET)

4、上传oled_app到开发板
使用scp或者nfs服务下载到板子

scp  oled_app root@192.168.42.1:/root/

5、使用

./oled_app 147258

6、其他功能
换行显示可以修改
oled_app.c
使用控制台传入多个参数
实现换行显示
本人小白就不完善了

你好，请问你用的是Duo64M吗，我用Duo256M运行程序显示i2c_ioctl failed，是因为尚Duo256M不支持 wiringX 和 pinpong 库吗？

3

用的milkv-duo 64M，编译通过的话，256M应该也没问题，你可以用i2c工具看看你的iic设备正常嘛

4

这个实验我采用的是iic1，通过duo-pinmux设置为iic引脚

5

imho, in our case it seems we need to change fd = open(“/dev/i2c-1”, O_RDWR);//打开设备节点 可读可写 to i2c-2, since duo-pinmux -r GP11 is [v] IIC2_SCL, rather than IIC1

感谢，找到问题了，引脚名和DUO的物理引脚名不是一一对应的，导致iic设备没连上 :joy:

7

我咋没看懂，你说的什么，老铁，我不知道你说的是什么

8

你要用那个i2c总线，就配置相应的引脚为iic模式，然然后去操作/dev/i2c-x

9

You can simplify the i2c-smbus/ioctl calls with a couple of defines to reduce repetitive use of OLED_CMD and OLED_DATA, e.g.

#define oled_cmd(cmd) OLED_WR_Byte (cmd, OLED_CMD)
#define oled_data(data) OLED_WR_Byte (data, OLED_DATA)

Otherwise, looks good. Thanks!

Why do you link against wiringx in the Makefile, e.g. LDFLAGS += -lwiringx? Can’t you just pull the pin mapping from wiringx and include it and do away with wiringx altogether?

10

Because I need to use that library when compiling other files, I copied it when compiling it, and it doesn’t have any impact if I write it down

11

Thank you, your suggestion is great. Using macro definitions can indeed simplify this program
