I have been making good progress on my current project and am about to start on the serial link but have a couple of questions.
The serial link is "one way" due to radio limitations.
One Arduino (probably a Mini) will be connected to an I2C sensor (10 DOF module), will read three inputs (2 16 bit values and 1 24 bit value), and transmit the three values on a one-way serial link to the receiving unit, an Arduino Uno, at a remote location. The receiver will do some data manipulations and display the current values.
I have a couple of questions about the serial link.
Does that Arduino serial REQUIRE two-way serial communications for hand-shaking or can they operate "blind"?
I assume that the Arduino software will break up the multi-byte values and transmit them as two or thee 8 bit words? Hopefully it puts them back together in the receive software! It would be easier for me to manipulate the data as a single long binary that having to convert everything to a BCD or HEX string.
For development and debugging I plan to have both Arduinos connected to the same desktop on two different COM ports
- In my preliminary reading I saw a statement that and Arduino can NOT operate two serial ports at the same time (eg. the console port and a different port to another board) - is that so?
That would be a PITA if I can't use the Serial Monitor function while developing the software!
Who is intimate with Arduino serial behaviour?
