Hi,
我在用G474 HRTIM驱动BLDC电机，尝试使用ADC trigger在下管导通时（CMP2作为reset source）去触发低侧电流感应。现在的问题是即使CMP2中断回调可以被正常调用，PWM波形也正常，ADC依然没被触发。
因为没有使用CubeMX生成代码，是对着Cube包内的Example抄的，所以我想可能是某些信号配置在硬件上不可实现。但是我检查了Datasheet和用Cube生成的代码，我的配置是可以实现的。
ADC和HRTIM配置如下：

[md]Hi,
最后确认问题在
其中Tigger和UpdateSource设置错误的被对调了，交换就可以正常触发。
感谢您的帮助
[md]哦，可以了。
我这边找到原因了，之前认为CMP2事件不可以，是因为我代码方面的原因。
之前 我针对HRTIM做了其它测试，对CMP2的比较值做了特别处理。 我屏蔽相关代码后，
Trigger 6/on tima cmp2也是可以的。
[md]哦，HRTIM作为ADC的trigger可以有很多个，我刚好是基于 ADC Trigger 1做的测试，它刚好不支持TIMA CMP2事件作为触发源，没有进一步看其它的Trigger。
所以，我那里只是针对 ADC Trigger 1所言的。TIMA CMP2事件其实可以作为其它trigger源的，谢谢指正。
另外，我觉得ADC能否触发和数据的提取是基于中断还是DMA方式没有什么关系。 至少先要被触发启动。
TIMA的CMP1和CMP2事件没法做ADC1的启动触发源，我们可以尝试使用其它hrtim事件，比方
CMP3、CMP4事件。
下面就是我基于CMP3事件来触发ADC，DMA搬运转换结果的截图。
Hi,
感谢你的回复，我试图改用了CMP3触发，依然是
HAL_HRTIM_Compare3EventCallback可被观察到调用，ADC仍无法触发。值得注意的是，我使用的是ADC中断模式，这是否会造成问题？我在继续尝试其他组合。另，我觉得你说的没有道理，请问CMP1/CMP2不能触发ADC1是实测出来的吗？但是，参照RM0440，p.382：
ADC1可以连接到TRG6，而TRG6显然可以由CMP2触发（p.924，RM0440）：
且该组合在CubeMX6.12.0可以正常生成代码不报错：
同时 我的NUCLEO版本是C04，其上搭载的芯片是rev.X，我未在勘误表中找到关于该问题的描述，请问这是否是一个芯片缺陷？
Hi,
再三确认，
ADC_HandleTypeDef的State成员为0x100，HAL_ADC_STATE_REG_BUSY，这指示ADC就绪且准备触发，因此可以确定不是数据获取的问题，也不是ADC发生了什么错误。令人疑惑的是HRTIM的波形输出依然正常，若通过软件触发ADC也正常，不像是什么配置错误。
我试着用CubeMX生成代码试试
请问STM32提供监听event的调试功能吗？
[md]后来，我使用你配置做了验证测试，即Trigger 6/ on TIMA cmp2来触发ADC，失败了。
若换成PER事件是可以的。后来，我尝试换成TIMA cmp4事件，也是可以的。不论中断还是DMA方式获取数据都可以。
你可以考虑换用别的CMP事件，至于为什么选择TIMA/CMP2做Trigger不行，一时半会还无法定论，得慢慢找原因。
[md]我这里用CubeMX生成代码 Trigger6+TIMA CMP2触发，是可以正常转换的，您再确定一下？
[md]我更多地是给你些确认和协助，搞定就好，这里细节太多了~！
