LPC55S69 LADC software trigger option

sanders7284 — Wed, 16 Nov 2022 13:37:08 GMT

Hello, looking for some advice please, I am using the MCUXpresso config tools to set up an ACD instance. I have created a command and a trigger, but want to call the conversion from within a loop. The tools state a software trigger is available, are there any worked examples of this please? Images and code generated attached.
