  • Reading/Writing Bytewide GPIO

    Read GPIO Bus - 61H returns BUS0..BUS7, how do I read Bus P8..P15?

  • #2


    Using the pin_ Commands, the bus is only 8 bits wide

      I figured that might be the case, however, the manual lead me to think otherwise

      Extract from: PICASO-SGC Command Set - Software Interface Specification
      2.1.11 Read GPIO Bus - 61hex
      Command cmd
      cmd 61(hex) or a(ascii) : Command header byte
      Response bus_status
      bus_status Returns 1 byte BUS0-BUS7 status.
      Description Reads the state of the GPIO Bus (BUS0-BUS7 or P8-P15
      ).
