STM32C8T6有2个ADC,ADC1和ADC2
一：介绍
1:简历
ADC（Analog-Digital Converter）模拟-数字转换器
ADC可以将引脚上连续变化的模拟电压转换为内存中存储的数字变量，建立模拟电路到数字电路的桥梁
12位逐次逼近型ADC，1us转换时间
输入电压范围：0~3.3V，转换结果范围：0~4095
18个输入通道，可测量16个外部(GPIO)和2个内部信号源(内部温度传感器和内部参考电压)
规则组和注入组两个转换单元
模拟看门狗自动监测
输入电压范围 STM32F103C8T6 ADC资源：ADC1、ADC2，10个外部输入通道
12位逐次逼近型ADC，1us转换时间 :
分辨率 : 一般用多少位来表示，12位AD值，它的表示范围就是0~2^12-1,量化结果的范围是0~4095 , 位数越高，量化结果就越精细，对应分辨率就越高
转换时间: 就是转化频率AD转换是需要花一小段时间的，这里1us就表示从AD转换开始到产生结果，需要花1us的时间。对应AD转换的频率就是1MHZ , 这个就是STM32 ADC的最快转换频率
规则组和注入组两个转换单元:
普通的AD转换流程是，启动一次转换、读一次值 , 然后再启动、再读值，这样的流程 ;
STM32的ADC就比较高级: 可以列一个组，一次性启动一个组，连续转换多个值 , 并且有两个组，一个是用于常规使用的规则组 ,一个是用于突发事件的注入组
注入组：相当于中断，可以打断规则组，用于处理紧急的事件
2:逐次逼近型ADC
ADC0809 : 独立的8位逐次逼近型ADC芯片
EOC是End of Convert : 转换结束信号
START : 是开始转换，给一个输入脉冲，开始转换
CLOCK : 是ADC时钟，因为ADC内部是一步一步进行判断的
REF+和VREF- : DAC的参考电压
3:ADC基本结构
4:输入通道
5:规则组的4种转换模式
在初始化ADC时配置的参数
单次转化 : ADC 执行一次转换，然后，ADC 停止
连续转化: 与单次转换不同的是，它在一次转换结束后不会停止 , 而是立刻开始下一轮的转换，然后一直持续下去 , 这样就只需要最开始触发一次，之后就可以一直转换了
扫描模式 : 在组中填几个通道几个通道就有效 , 填入多个的时候应避免覆盖的问题, 使用使用DMA
非扫描模式 : 这个组就只有第一个序列1(Rank排名)的位置有效 , 这时选中一组的方式就退化为简单地选中一个的方式了。序列1(Rank排名)可以放任意的通道。
X.ADC_ContinuousConvMode=DISABLE;//选择是连续转换还是单次转换---单X.ADC_ScanConvMode=DISABLE;//可以选择是扫描模式还是非扫描模式---非扫描模式
1:单次转化,非扫描模式
在非扫描的模式下，这个组就只有第一个序列1的位置有效 , 这时选中一组的方式就退化为简单地选中一个的方式了
我们可以在序列1的位置指定我们想转换的通道 , 比如通道2 ， 然后，我们就可以触发转换，ADC就会对这个通道2进行模数转换 , 过一段时间转化完成 , 转换结果放在数据寄存器里，同时给EOC标志位置1----转换过程就结束了 . 我们判断这个EOC标志位，如果转换完了 , 可以在数据寄存器里读取结果了 , 如果我们想再启动一次转换，那就需要再触发一次 , 转换结束，置EOC标志位，读结果
2:连续转化,非扫描模式
首先，它还是非扫描模式，所以组列表就只用第一个 , 与单次转换不同的是，它在一次转换结束后不会停止 , 而是立刻开始下一轮的转换，然后一直持续下去 , 这样就只需要最开始触发一次，之后就可以一直转换了
优点 : 开始转换之后不需要等待一段时间的 , 它一直都在转换，所以你就不需要手动开始转换了 , 也不用判断是否结束的 , 想要读AD值的时候，直接从数据寄存器取就是了
3:单次转化,扫描模式
这个模式也是单次转换，所以每触发一次 , 转换结束后，就会停下来 , 下次转换就得再触发能开始
扫描模式 : 会用到这个组了 , 在序列中填入通道 , 这里每个位置是通道几可以任意指定，并且也是可以重复的 , 初始化结构体里还会有个参数，就是通道数目 (x.ADC_NbrOfChannel=) 比如这里指定通道数目为7，那它就只看前7个位置,那么x.ADC_NbrOfChannel=7, 它就会只对前7个AD通道进行转化, 转换结果都放在数据寄存器里 , 这里为了防止数据被覆盖，就需要用DMA及时将数据挪走 , 那7个通道转换完成之后，产生EOC信号(EOC置1)，转换结束 , 然后再触发下一次，就又开始新一轮的转换
使用DMA---避免通道数据覆盖
因为这里只有一个规则组的数据寄存器 , 如果使用了 扫描模式在一个组中开启了7个通道, 只会有最后一个通道被保留下来, 前面的6个通道会被覆盖掉. 最后只会得到一个通道.
使用这里使用MDA在下一个通道来之前, 把现在的数据放到了MDA中, 避免出现通道的覆盖问题
4:单次转化,扫描模式
次转换完成后，立刻开始下一次的转换 , 也开启组
6:触发控制
下面是规则组的触发源
注入组的触发源
7:数据对齐
ADC初始化中的配置---X.ADC_DataAlign
我们这个ADC是12位的，它的转换结果就是一个12位的数据 , 但是这个数据寄存器是16位的，所以就存在一个数据对齐的问题
右对齐 : 就是12位的数据向右靠 , 就是12位的数据向有靠 , 高位多出来的几位就补0 ,一般
使用右对齐, 这样读取这个16位寄存器，直接就是转换结果
左对齐 : 是12位的数据向左靠 , 低位多出来的几位补0 , 得到的数据会比实际的大 , 数据左对齐实际上就是把数据左移了4次 ,数据左移一次，就等效于把这个数据乘2 , 直接读取的话相当于把数据扩大了16倍 .
8:转化时间
9:校准
ADC有一个内置自校准模式。校准可大幅减小因内部电容器组的变化而造成的准精度误差。校准期间，在每个电容器上都会计算出一个误差修正码(数字值)，这个码用于消除在随后的转换中每个电容器上产生的误差
建议在每次上电后执行一次校准
启动校准前， ADC必须处于关电状态超过至少两个ADC时钟周期
10:间断模式
规则组：
扫描模式下的一个细分。
- 间断模式：区别于扫描模式连续扫描完整的一组通道，间断模式将一组通道分为多个短序列，每次外部触发事件执行一个短序列的扫描转换。
- 必须使能扫描模式，禁止使用连续模式(为了方便我们的观察，可以禁止，手册中没有强制的要求)，必须避免同时为规则和注入为间断模式。
n:一个子组中几个成员。上面为3个
每次一个信号的到来，转化一个字组。
注入组：
注入组间断模式和规则组是一样。
唯一的不同是：注入组的n=1;不能为其他的数，规定。
注入组和规则组的中断触发时机不同。
规则组：
当完成一个子组（即n个通道）的转换后，会触发一个中断请求，进入中断回调函数。
HAL_ADC_ConvCpltCallback
注入组：
当所有的子组完成，进入中断回调函数中去。
HAL_ADCEx_InjectedConvCpltCallb（）
11:ADC的硬件电路
12：温度传感器
STM32F103C8T6内部的ADC（模拟数字转换器）的温度传感器在微控制器中起着关键作用，主要用于测量和监控芯片内部的温度。
- 该温度传感器在-40℃至+125℃的范围内进行测量。
- 由于是内置的简化温度传感器，其精度相对较低，大约为±1.5℃。
- ADC的分辨率为12位，这意味着它能够提供相对较高的温度测量精度
ADC_in16和ADC_IN17是内部的通道，没有物理引脚。
接下 来我们介绍一下和温度传感器设置相关的2个地方。
第一个地方，我们要使用STM32的内部温度传感器，必须先激活ADC的内部通道，这里 通过ADC_CR2的AWDEN位（bit23）设置。设置该位为1则启用内部温度传感器。
第二个地方，STM32的内部温度传感器固定的连接在ADC的通道16上，所以，我们在设 置好ADC之后只要读取通道16的值，就是温度传感器返回来的电压值了。根据这个值，我们 就可以计算出当前温度。
公式
温度 = (V25-Vsense ) / Avg_Slope + 25°C
V25 是温度传感器在25°C时的输出电压。（典型值为：1.43）
Vsense 是当前温度下的温度传感器输出电压，可以通过ADC读数转换得到。
Avg_Slope 是温度传感器输出电压随温度变化的平均斜率（单位：mV/°C）。//4.3
25°C 是参考温度，即V25对应的温度。
如电压为3v时
温度=(3.0-1.43)/4.3+25
二：HAL配置

关于复用：
ADC1_IN6引脚在PA6上面，我们的定时器的通道6也在PA6上面，(PA6是在通道6)，为了防止我们在做扫描模式的时候引脚冲突，我们在这里直接把他引脚重新定义为PB4上面；--这个实验做不做复用都一样，后面的扫描模式的使用。

}H:如何一次触发信号使得DMA完成转换
上面的都为每发生一次事件（更新事件或者为捕获事件）都会触发一次AD的转化，不过我们开启了DMA的转运，每次ADC的转化DMA会把数据拿到我们指定的内存（数组中），一共转化10次ADC，才会触发一次DMA中断。所以我们需要按下10次按键才会触发一次数据的打印。
这个代码解决这个问题，按一次，打印一次。不过需要开启连续转化模式。

{if(GPIO_Pin==GPIO_PIN_11){ printf("PB11产生中断\r\n");ADC_HandleType.Instance->CR2 &=~ ADC_CR2_CONT;}}因为ADC的触发方式配置为：
ADC_HandleType.Init.ExternalTrigConv=ADC_EXTERNALTRIGCONV_EXT_IT11;//触发方式：EXT_IT11中断
所以在配置PB11引脚的时候，需要注意（只能在下面选）：
PB11不能使用：
GPIO_MODE_INPUT
GPIO_MODE_AF_INPUT
GPIO_MODE_ANALOG规则组 扫描模式
A:规则组10通道扫描 单次转换DMA方式
因为开启了扫描模式，在扫描模式中开启的10个通道，一个组中的10个通道全部转化完毕，中断标志位才会置位。然而我们只有一个数据寄存器（DR），会导致我们的数据出现覆盖。所以不能使用中断或者轮询

规则组：
规则组只有一个DR寄存器，因为开启了扫描模式，在扫描模式中开启的6个通道，一个组中的6个通道全部转化完毕，中断标志位才会置位。然而我们只有一个数据寄存器（DR），会导致我们的数据出现覆盖。所以不能使用中断或者轮询
注入组：
注入组一共有4个通道，每个对应一个寄存器，所以可以使用中断和轮询方式，不会出现数据的覆盖问题。
中断问题
注入组使用的是我们ADC的中断方式所以，需要打开中断和NVIC.
ADC中断函数会关闭我们注入组的中断标志位，所以我们需要自己在注入组的回调函数中自己在开一遍

可以参考我写的：
CSDN
https://mp.csdn.net/mp_blog/creation/editor/136916809
我们的ADC是12位的，也就是说取值范围为：0X000----0XFFF
我们选取一个上限制和一个下限制，当我们的值在这个范围内属于正常值。一但高于或者低于就属于异常值，会触发模拟看门狗中断。

关于ADC1_Init ()和ADC2_Init
我们在主函数中首先初始化的是ADC1,在初始化ADC2。所以基本上开启什么的通道都放在了ADC2上面。
在同步规则模式中，必须转换具有相同时间长度的序列（软件触发）
ADC1和ADC2的通道数必须相同。

当所有ADC1/ADC2注入通道都被转换时，产生JEOC中断(若任一ADC接口开放了中断)。
关于中断：打开任意一个就ok了。
打开主模式（ADC1）的中断，在注入组中断回调函数中不需要再使能注入组的中断。（中断不会被关闭）
打开从模式（ADC2）的中断，需要再注入组的中断回调函数中再次打开注入组中断。（中断被关闭）
