Displaying FLOAT variables in Arduino. It seems that the Arduino software doesn't have much support for displaying float variables, certainly the sprintf() function doesn't work. However there is a useful c function called dtostrf() which will convert a float to a char array so it can then be printed easily.

RS485, RS422 and RS232 Differences and Typical Applications. Why use RS232 vs RS485 and what is the real difference between RS422 Vs RS485? First, lets define each one. Keep in mind that all three are considered SERIAL, as opposed to IEEE-488 which is PARALLEL.

Data Acquisition RS485. Understanding RS485 and RS422. Those familiar with RS232 will know that the standard defines how RS232 lines should be driven electrically: what they are called, what information they carry and even the connectors and pin numbers to use. RS422 and RS485, by contrast, define only the electrical characteristics of the driver.

Nel precedente articolo abbiamo visto le basi per creare una rete RS485 che permetta di connettere multiple schede Arduino fra loro. In quell’occasione abbiamo collegato due schede Arduino insieme che si inviavano in modo autonomo dei semplicissimi caratteri ed una delle schede quando riconosceva il carattere inviato dall’altra accendeva il led sulla porta 13.
