Hi!
I'm designing a device that uses three m8:s that communicate over a single wire using UARTs. By only enabling the UART outputs (TXEN) when actually transmitting anything all three uCs can share single line.
But turning TXEN on and off between transmissions create noise, so I'm trying to figure out how long time to wait when enabling/disabling before sending data.
Any clues?
Has anyone done this before?
My oscilloscope is not good enough to tell me, and I have searched the forum and googled for it.
