stm32 timed multichannel ADC DMA conversions on STM32F030k6

Yet another "note to future self" video about STM32 DMA ADC acquisition.  This time, multiple channels are being sampled into a buffer, triggered by a TIM1 event, rather than by repetitive software calls.
This way, the ADC subsystem does its thing in the background and your code can react when it's ready.
Sorry for the ghastly video and audio production values.  I'm not a pro.
