Is only a single async UART supported on the NrF52 832/840 devices?
Is only a single async UART supported on the NrF52 832/840 devices?
This is in the product spec. 1 for the 52832, 2 for the 52840
Thank you . I thought I had read the 832 data sheet incorrectly. Then could not find where the 840 document actually said there were two. In fact, the 840 spec only shows one on its page12 block diagram . Where is the 2nd uart documented in the spec?
You read the 52832 sheet correctly, the second UART is here
40 0x40028000 UARTE UARTE1
Universal asynchronous receiver/transmitter with EasyDMA, unit 1
just work your way down the peripheral list
Thanks. I guess they missed this when updating the 840 block diagram
