    If you just want to use the module to display 'stuff' as sent from the PC then all you should need is



    PC -> wifi Module Tx+Rx ///(wifi signals)/// -> wifi Module Tx+Rx -> MD1 -> projector/monitor



    PC would be running C code tranmitting commands to a serial port which the wifi module is connected to. Assumes the PC end wifi module is RS232 serial and the MD1 end wifi module is TTL serial
    can the MD1 display for example, a powerpoint presentation from the PC? do I still need to program the MD1 incase? since I dont need the uC anymore as of your diagram.

    Thanks for further replies.

      Your PC application would have to read the PPT (somehow, ole?) convert it into the required format and resolution and then send it to the MD1 (most likely using 'display image' command).



      By using multiple display pages you can build up one page whilst displaying another, giving the appearance of instantaneous page sawpping

          MD1 Manual Page 38, but I thought you said you'd read the manual.

          The wifi module I have seen only needed programming once, from then on it acted as a 'pass through' device. But really, we don't sell wifi devices so you should get your support from your wifi supplier. If your module is not programmable or doesn't support passthrough you should consider upgrading it, otherwise you are going to need a processor at the far end, for no real reason.

          You program that using the program you write on your PC.

            I will.

            oh so i need to buy 1st the uUSB device or can I use a homemade device for my MD1..

            thanks for further replies.

              Hello again. I'll ask this question again. Can I use a Microcontroller to send the serial hex commands needed by the uVGA Picaso MD-1 to display something?

              My new project will be like this
              PC -> microcontroller -> ethernet ->microcontroller -> MD1 -> monitor.

              this would do: I will enter a text that will be sent on a serial and it will be displayed by the MD1. Is it possible? any replies will be appreciated. thanks.
