    Psoc5 UART 485 hardware enable

    jim.gilmartin

      In the component setup under advanced there is a box labeled "RS-485 configuration options"--- with a check box marked "Hardware TX-Enable"

         

      I assume this is for the output pin to pull the enable on the 485 chip high for transmit. Is this correct? If so I cant get it to work and pull the output pin high.

         

      Ive been just using the pin enable and disable functions in the interrupt to switch from transmit to receive.

         

      I cant seem to find the code either that enables the pin. Does anyone have any idea of where it is in the API or is it a hardware function?

         

      Thanks
