Hi,
If an ESB PRX has queued a 250-byte auto-ack payload, that will take around 2ms at 1Mbs to transmit.
If the ESB PTX has the standard 250us repeat interval, will the...
I am confused about the value of RX_PW_Px register what will be the value of this register if more than 1 dynamic payload packet arrives on the same pipe-x.
I'm a beginner I'm having hard time understanding UART. In my opinion, the documentation is going too straight to the technical details and tutorials without even starting...
