  • Fastest/Best baud rate

    I am planning to drive the 43dt via the usb cable to a small embedded pc, occasionally I want to upload a bitmap, what is the best/fastest reliable baud rate to use?

    That is very dependent on the usb cable used, as they all have different 'top baud rates' and some need specific 'non-standard' settings to achieve this. Which one are you using?

    Also, some of these cables don't actually transfer data any faster when you increase the baud rate, they just increase the gap between each byte.

    In the past I have achieved this at the 'standard' 115200 baud (uploading the bitmap in the background during periods of inactivity), this works for all cables.

      115200 is easy, I was planning to use the adapter that came with the display, my question is more about what the 43dt chip is capable of.

        See the description of com_SetBaud() in the internal functions reference

          OK I modified the SPE with the following
          com_SetBaud(COM0,62500); // NB /10 !!!!

          and it runs at 625000 baud just fine
