Helloo from Germany..
i call a Duinomite Mini and a Duinomite Mega my own.. i use the Mini with an ArduinoAdator together wit an Ciseco SRF Shield ..this have the Com Port at D0 and D1 . Now i wish to use the Duinomite Mega together with the SRF Shield ( its an RF Module with 868 Mhz )so i need the hardware Uart with 115200 Baud at the Pins D0 and D1
what i have to do to get this to work ? ( i dont need the Rs232 Connector)
thanks Ron
Just connect and it looks like it will work - but it may be that if you use BASIC that it does not use it as a hardware uart or maybe does not support 115200. You'll have to check that.
The 330R I see on RX will (I think) be fine. Worst case you could cut the PCB traces for RX / TX.
John
thank you for your answer John..,
it works with the Duinomite Mini very well
the resistors R2 and R3 are 0 (zero) ohm (Duinomite Mega), should i cut the wire brige and solder an 330 ohm resistor in it ?
thanks Ron
I was thinking that R42 will already allow what you want. I can't try it now and may be wrong, so see what you think.
John
the problem is solved. I cut the connection RX and TX (leg 11 and leg 12) for chip 3232 . It works ! :) . Com4 is now available at D0 and D1 Aduino Header
now I can fit the Mega into my new BOPLA Enclosure
thank you very much
Good news!
