Part Number:AWR2243 Hi, In the figure below, what are the recommended values for ADC valid strat time and excess ramping time before and after ADC sampling time? Best regards, Hiroyuki Taguchi Hi, Please see this Appnote https://www.ti.com/lit/an/swra553a/swra553a....

最后一个配置是Trigger mode触发模式,这里默认是Trigger will automatically step to next memory conversion register也就是如果你勾选了重复模式会给下一个触发信号的原因(只需要一个start函数就会一直跑)但是如果要用定时器事件触发的话这里就要勾选Valid trigger will step to next memory conversion register,不要自...
