初始化子程序：

START

0x7C； I2C子地址

0xEA；ICSET，軟件復(fù)位芯片

0xC0；MODSET，關(guān)顯示

0xF0；BLKCTL，關(guān)閃爍

0xA3；DISCTL，80Hz Line inversion，High Power mode

0xE8；ICSET，清復(fù)位bit1

STOP

顯示刷新子程序：

START

0x7C；I2C子地址

0xF0；BLKCTL，關(guān)閃爍

0xA3；DISCTL，80Hz Line inversion，High Power mode

0xE8或0xEC；ICSET，顯存高位地址為0或1

0xXX；ADSET，設(shè)置顯存刷新起始地址，通常為0x00，從頭開始刷新，此時上一條指令一般為0xE8

STOP

START

0x7C

0xC8；MODSET，開顯示

STOP

最后附上簡單的測試程序：

#define Address_BL55072   0x7C

void BL55072_Init(void)

{

uint8_t BL5502_Init_BUFF[5];

BL5502_Init_BUFF[0]= 0xEA;

BL5502_Init_BUFF[1]= 0xC0;

BL5502_Init_BUFF[2]= 0xF0;

BL5502_Init_BUFF[3]= 0xA3;

BL5502_Init_BUFF[4]= 0xE8;

HAL_I2C_Master_Transmit(&hi2c1, Address_BL55072, (uint8_t *)BL5502_Init_BUFF, 5, 100);

}

uint8_t BL5502_BUFF[23];

void SEG_WriteBuffer(uint8_t data)

{

BL5502_BUFF[0]= 0xF0;

BL5502_BUFF[1]= 0xA3;

BL5502_BUFF[2]= 0xE8;

BL5502_BUFF[3]= 0x00;

for(int i=4;i<22;i++) 

{

BL5502_BUFF[i] = data;//

}

HAL_I2C_Master_Transmit(&hi2c1, Address_BL55072, (uint8_t *)BL5502_BUFF, 22, 100);

BL5502_BUFF[0]= 0xC8;

HAL_I2C_Master_Transmit(&hi2c1, Address_BL55072, (uint8_t *)BL5502_BUFF, 1, 100);

}
