本文介绍了将ssd1306与stm32f103连接到寄存器上，i2c``数据模式''不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想使我的第一个在stm32上使用i2c的应用程序可以与ssd1306一起使用.所有在命令模式"下的通讯都在工作，并且显示屏对1字节命令做出反应.我认为问题是在数据模式"下，当一个打包的字节数增加时.
I want to make my first application that uses i2c on stm32, to work with ssd1306. All communication in 'command mode' is working, and display reacts for 1 byte commands. I think problem is in 'data mode' when number of bytes in one packed is increased.
通过i2c发送数据的基本功能
void i2c1_send(uint8_t address, uint8_t *command, uint16_t length)
{
while(I2C1->SR2 & I2C_SR2_BUSY);
I2C1->CR1 |= I2C_CR1_START;
while(!(I2C1->SR1 & I2C_SR1_SB));
I2C1->DR=address; //7 bit address in this byte is already shifted left by one
while(!(I2C1->SR1 & I2C_SR1_ADDR)|!(I2C1->SR2)); //waiting for address match
for (uint16_t i=0;i<length;i++)
{
I2C1->DR=command[i]; //filling buffer with command or data
while(!(I2C1->SR1 & I2C_SR1_BTF)); //from RM: Note: The BTF bit is not set after a NACK reception
//i think i need here to wait for ack response
}
I2C1->CR1 |= I2C_CR1_STOP;
}
发送命令的功能，它工作正常，它可以汇总发送3个字节的数据，而无需启动/停止- [startBit，Address，ControlByte，CommandByte，stopBit]
Function to send commands this works fine, it sends in summary 3 bytes of data without start/stop - [startBit, Address, ControlByte, CommandByte, stopBit]
和代码:
void ssd1306_sendCommand(uint8_t toSend_u8){
uint8_t frame_u8[2] = {0, toSend_u8};
i2c1_send((OLED_ADDRESS<<1)|0, frame_u8,2); //sending frame
}
命令模式下的控制字节为0x0，请参见ssd1306数据表.
Control byte in command mode is 0x0, according do ssd1306 datasheet, it will be shown on image later.
最后发送数据的功能，该功能不起作用
void ssd1306_sendData(uint8_t* toSend_u8p,uint8_t data_lenght)
{
uint8_t frame_u8[256]; //making frame buffor to send
frame_u8[0] = 0x40; //control byte with D/C = 1 ---> 0b01000000 = 0x40
for(uint16_t i=0; i <= data_lenght; i++){
frame_u8[1+i] = toSend_u8p[i];
}
i2c1_send((OLED_ADDRESS<<1)|0, frame_u8, data_lenght+1); //data_lenght+1 because we have additional control byte
}
i2c数据格式drom ssd1306数据表:
i2c data format drom ssd1306 datasheet:
我的i2c初始化fx
void i2c1_init()
{
RCC->APB2ENR |= RCC_APB2ENR_IOPBEN; //enabling gpios
RCC->APB1ENR |= RCC_APB1ENR_I2C1EN; //clock for i2c1
__DSB();__DSB();__DSB();
//i2c pins : PB6 - SCL ; PB7 - SDA
GPIOB->CRL &= ~(GPIO_CRL_CNF6|GPIO_CRL_CNF7);
GPIOB->CRL |= GPIO_CRL_CNF6_1|GPIO_CRL_CNF7_1|
GPIO_CRL_MODE7|GPIO_CRL_MODE6; //AF function push pull for gpios
I2C1->CR2 |= 50;
I2C1->CCR |= I2C_CCR_FS;
I2C1->CCR |= 30;
I2C1->TRISE |= 51;
I2C1->CR1 |= I2C_CR1_ACK;
I2C1->CR1 |= I2C_CR1_PE;
}
我不完全了解问题所在，以及为什么这种数据模式"不起作用
I don't completly understand what is the problem, and why this 'data mode' is not working
推荐答案
此显示在I2C接口上有硬件错误(在错误的时间对RD/WR位进行采样，使其与AT32UC3等某些设备不兼容，而没有小的硬件破解或SWI2C实现)，但是使用STM32应该没问题.
This display has a HW bug on I2C interface (sampling RD/WR bit at wrong time making it incompatible with some devices like AT32UC3 without small HW hack and or SW I2C implementation) however with STM32 it should be fine.
SSD1306 LCD的配置是关键，因为如果没有适当的初始化，LCD不会显示任何内容.并且倾向于卡在怪异的状态(在丢失配置或错误地发送VRAM数据之后)，该LCD倾向于卡住，直到电源关闭/打开为止.因此，当您反复尝试时，您需要始终关闭LCD的电源，我敢打赌，即使您的代码在一次尝试中都可以，也不要关闭LCD的电源，因为LCD卡住了.
The configuration of SSD1306 LCD is a key as without proper init the LCD does not show anything. And tend to get stuck in weird state (after miss configuration or sending VRAM data wrongly) this LCD tends to be stuck until power off/on. So when you trial and error you need to always power off the LCD which I bet you do not do so even if your code in one trial is OK you might miss it as LCD is stuck.
还有许多SSD1306驱动程序使用页面VRAM访问，这似乎不适用于我测试过的所有SSD1306(所有位置均为128x64).我改用水平寻址模式.
Also many SSD1306 drivers use page VRAM access which seems to not work for any of those SSD1306 I have tested (all where 128x64). I use horizontal addressing mode instead which works.
这是我自己的用于AT32UC3芯片的I2C LCD的旧C ++驱动程序:
Here is my own old C++ driver for this I2C LCD for AT32UC3 chips:

所以要么只提取初始化数据包并发送帧，要么直接使用它，但是在这种情况下，您需要使用任何可用的方法来实现 I2C_send 函数.
so either just extract the init packets and frame sending or use this directly but in that case you need to implement I2C_send function with whatever you have at your disposal.
在这种情况下，您还需要我的字体:
In such case you will also need my font:

#include "font_8x8.h"
#include "LCD_SSD1306_I2C.h"
LCD_SSD1306_I2C lcd;
// init
for (int adr=1;adr<128;adr++) // find I2C device
if (I2C_probe(adr))
{
lcd.init(adr,128,64); // LCD address and resolution
break;
}
// render
lcd.clrscr();
lcd.prntxt(0,0,"test LCD");
lcd.pixel(10,10,true);
lcd.rfsscr();
只需交换I2C _ ???东西随身携带.
just exchange the I2C_??? stuff with what you have.
仔细研究 init 和 rfsscr 函数，并根据您的工作进行参考，并对其进行修复/测试，直到其正常工作为止.
Take a close look to init and rfsscr functions and corssreference with what you do and repair/test until its working...
别忘了关闭电源，然后再进行任何测试！！！
