试过了,也不行
在手册5.1.2 external trigger中讲
Through the pin-44 of CN1(ExtTrig),the A/D conversion also can be performed when a rising edge of external signal is occurred
但在5.1.4 trigger acquisition modes中又讲
Use about-trigger acquisition in application where you want to collect data before and after a specific trigger event.The digital trigger is input from pin 46(TGIN) on CN1.
请教pin 44和pin46到底都是什么用途? 在用外部时钟模式时,从pin 46输入是可以采集的
