  • uUSB-MB5 and Host

    I was wondering if I could interface the uUSB-MB5 to a external microcontroller to send serial commands to the uOLED-32024-P1 display? I tried to interface the module to a PICmicro by itself to see if it could accept serial commands.

    Can I get the uOLED-32024-P1 to accept commands this way instead of using the serial emulator PC program?

      Thanks for responding!!! Sorry to reply so late I was busy with exams. I do have another question. If I interface the uUSB-MB5 to an external micro controller to receive serial comands to control the any uOLED display whats the advantage of me do this? Is it any different than interfacing the uOLED-32024-P1 display to the microcontroller itself?

        Hi bradgm,

        There isn't many advantages to interface the uOLED-32024-P1 (or any 4DGL capable display for that matter) to an external processor that will receive serial commands:
        - It adds an extra (unnecessary) layer between the command sender and the screen.
        - More complicated set up (extra hardware...), induce risk of errors and failures (both in hardware and software).
        - Needs extensive testing.
        - Depending on which external processor you choose, it is possible that the one on-board the uOLED-32024-P1 might be more powerful !

        I suggest that you consider using the uOLED-32024-P1's on-board processor for that matter, in fact that's what the Serial Platform Emulator is about:
        http://www.4dsystems.com.au/code/index.php?node=26&id=51

        It will translate serial commands received to control the display, it is tested, efficient, free, customizable, and does not need extra harware

        Regards,
        Julien

          Hello, Julien Thanks for responding!!!. I thought that using the uUSB-MB5 and the uOLED-32024-P1 display with a external microcontroller would work. I wanted to use this module without using the serial emulator but issue serial commands from an external microcontroller just like the uOLED-128-GMD1.

          Unfornately, I had no luck because I have tried sending serial commands to the module with the serial emulator which works fine. However, Is there any way I can still uUSB-MB5 and the uOLED-32024-P1 without using the serial emulator?
