Yes you can.
Every pin labeled "5V" in this picture

are the same.
Also with pins "GND"

I am also new to Arduino...

I think, Firmata is for IOs like read, write, PWM and so.

But I remember somthing like terminal connection via Arduino somewhere in this forum.
Very simple, just copying the characters from USB-recieve to Serial-transmit and back...

On the original subject again. That D0 and D1 (pins 2 and 4 on the 20Way header), the adruino UART1. Is there an example on how to use it, because I had a look at the C# library and wasn't able to find something like Adruino.Serial(blah blah blah) You can find examples of arduino software at the ar...

"If you can't see grandpa zoom in the picture"..... I had a better look at the picture and I finally saw that I am supposed to use pins 5 and 7. And the loop test does work
But!!! That 1.8V operating voltage, is it referring to the serial voltage levels as well?

Yes

Even though I sometimes don't sound like that, but I am happy to be able to help.

Is there a library to use the CPU I2C on Linux..or any information about I2C so we can try to make it work? Thanks! Hi, what kinds of info would you need, i will try to provide. Looking forward to your reply! We are still waiting for the source code of a working example including the window driver ...

The confusion is your documentation states this connector is connected with the Z8350 core. So pins 6&8 are on the Adrino? Mike I don't think so... I believe that pins 6&8 are connected to Z8350 CPU... just because of the voltage of 1,8V. Maybe "LattePanda" is mixing things. I would bet, that we ju...

Should I use the MAX3218? Whether or not you need to use any RS232 Transciever depends on the devices you have connected to each other. Is the logic level at both 1.8V then not. If there is an RS232 input with the specific RS232 signal level in the other device, then yes. RS232 is a hardware specif...

Signals at this connector are 1,8V digital level.
1,8V = High, 0V = Low
Are you using an RS232 converter like MAX3218 ?

You can write your software on a "big" PC and then use "remote debugging with Visual Studio" to run your app on the LP.
