初始化子程序： START 0x7C； I2C子地址 0xEA；ICSET，软件复位芯片 0xC0；MODSET，关显示 0xF0；BLKCTL，关闪烁 0xA3；DISCTL，80Hz Line inversion，High Power mode 0xE8；ICSET，清复位bit1 STOP
显示刷新子程序： START 0x7C；I2C子地址 0xF0；BLKCTL，关闪烁 0xA3；DISCTL，80Hz Line inversion，High Power mode 0xE8或0xEC；ICSET，显存高位地址为0或1 0xXX；ADSET，设置显存刷新起始地址，通常为0x00，从头开始刷新，此时上一条指令一般为0xE8 … … STOP
START 0x7C 0xC8；MODSET，开显示 STOP
最后附上简单的测试程序：
#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); }
