Folks,
Simple question:
When I set off A DMA transmission on the UART, how do I poll for that transmission having finished? There seem to be no status bits in this UART. Is that really right or am I just being blind? I've tried looking at the EVENTS_TXDRDY, but
It talks about an ENDTX "event" whatever an event is. I assume it's what the rest of the world calls an interrupt? However, I do not want an ISR.
There surely *must* be a way of doing this? I've looked at NRF_UARTE0->EVENTS_TXDRDY and NRF_UARTE0->EVENTS_TXSTARTED but from what I can tell they are of no use at all. Neither seem to change state once set.
Thanks.
