    Question

    Steve,

    Can you give a more detailed example of the BUSY line technique please?

    I am using a Master 16F628 with multiple Slave 16F628 using USART communication (HSERIN via TX/RX lines).

    I'd like to be able to use a BUSY line to indicate when the line is busy. At first thought I would think that HIGH = NOT BUSY and LOW = BUSY, that way there is no power signal at the same time as communication, less risk of disruption.

    NOTE: It is not known which Slave will be connected to the system. There might be none, or there might be several, that'S why I'm looking for a flexible way of Slaves to send data.

    Robert

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
