I need the start bit of UARTE

[tony55723]

Hi , 

I search nrf52810_bitfields.h , but i don't find about start bit , is the direction search for error ?

My idea : This is set up for stop bit , should the start bit be the same?

Hi,

There is no configurable amount of start bits for the UARTE peripheral. The CONFIG_STOP register is used to control if 1 or 2 stop bits should be used.

Best regards,
Jørgen

There should always be 1 start bit in the frame, you don't need to configure this.

You should be right.

Because I sent DMX512 (similar to RS-485), the device responded, although it was not the result I wanted.

Another article I published, can you help me, please?
