STM32对HMC7044进行配置的详细过程及代码_stm32 配置hmc7044配置

1.STM32的3线SPI初始化：

void spi_init()
{
	GPIO_InitTypeDef GPIO_InitStructure;	 
	RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB ,ENABLE); 
	GPIO_InitStructure.GPIO_Pin = GPIO_Pin_12|GPIO_Pin_13|GPIO_Pin_15;  //SLEN
	GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
	GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
	GPIO_Init(GPIOB, &GPIO_InitStructure);
	GPIO_ResetBits(GPIOB, GPIO_Pin_15);
}
void sdata_In_Init()
{
	GPIO_InitTypeDef GPIO_InitStructure;
	RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB ,ENABLE); 
	/*SPI SDATA PB15*/
	GPIO_InitStructure.GPIO_Pin = GPIO_Pin_15;  //SDATA
	GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
	GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
	GPIO_Init(GPIOB, &GPIO_InitStructure);	
}
 
void sdata_Out_Init()
{
	GPIO_InitTypeDef GPIO_InitStructure;
	RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB ,ENABLE); 
	/*SPI SDATA PB15*/
	GPIO_InitStructure.GPIO_Pin = GPIO_Pin_15;  //SDATA
	GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
	GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
	GPIO_Init(GPIOB, &GPIO_InitStructure);	
}

2.STM32对HMC7044的C函数：

 HMC7044数据手册上的读写时序图

void hmc7044_Write(unsigned long int addrData)
{
	int i = 0;
	
	sdata_Out_Init();
	HMC7044_SPI_SLEN  = 1;
	HMC7044_SPI_SCLK  = 0;
	HMC7044_SPI_SDATA = 0;
	delay_us(5);
	HMC7044_SPI_SLEN  = 0;
	//trans data
	for(i=0;i<24;i++)
	{
		HMC7044_SPI_SCLK  = 0;
		data2 = ((addrData>>(23-i)) & 0x1);
		HMC7044_SPI_SDATA = data2;
		delay_us(5);
		HMC7044_SPI_SCLK  = 1;
		delay_us(5);
	}
	HMC7044_SPI_SLEN  = 1;
 
}
 
uint8_t hmc7044_Read(unsigned long int addrData)
{
	int i = 0;
	uint8_t tempvalue = 0;
	
	sdata_Out_Init();
	HMC7044_SPI_SLEN  = 1;
	HMC7044_SPI_SCLK  = 0;
	HMC7044_SPI_SDATA = 0;
	delay_us(5);
	HMC7044_SPI_SLEN  = 0;
	//trans data
	for(i=0;i<16;i++)
	{
		HMC7044_SPI_SCLK = 0;
		data2 = ((addrData>>(15-i)) & 0x1);
		HMC7044_SPI_SDATA = data2;
		delay_us(5);
		HMC7044_SPI_SCLK = 1;
		delay_us(5);
	}
	sdata_In_Init();
	for(i=0;i<8;i++)
	{
		HMC7044_SPI_SCLK = 0;
		delay_us(5);
		tempvalue<<=1;
		HMC7044_SPI_SCLK = 1;
		if(GPIO_ReadInputDataBit(GPIOB,GPIO_Pin_15))
		{
			tempvalue++;
		}
		delay_us(5);
	}
	HMC7044_SPI_SLEN = 1;
	return tempvalue;
	
}

3.HMC7044需要按照芯片手册的顺序进行配置：

1.更新配置寄存器
2.配置PLL2寄存器
3.配置PLL1寄存器
4.配置SYSREF寄存器
5.配置输出通道的分频比等
6.软件重启：0x01寄存器

4.HMC7044的锁定检测：

PLL1锁定检测寄存器：
    0x007C的bit5为1表示已锁定
PLL2锁定检测寄存器：
    0x007D的bit3位1表示PLL1和PLL2已锁定
