RS485：
* It uses an SP485CN chip to handle comms.
* The screw terminals (assuming that the three jumpers are set to '485') marked 'A' and 'B' go directly to the IC 'A' and 'B' pins (6 & 7 respectively).
* The screw terminal marked VCC goes to the IC VCC pin (8), and also to the board's +5V line (i.e. the Arduino's +5V rail).
* The screw terminal marked GND goes to the IC GND pin (5), and also to the board's GND line (i.e. the Arduino's 0V rail).
* The chip's DI (Data Input?) pin (4) is connected to the Arduino's Digital Pin 1 (TX).
* The chip's RO (Data Output?) pin (1) is connected to the Arduino's Digital Pin 0 (RX), with a resistor pull-up to the +5V rail.
* The chip's DE (output enable) pin (3) is connected (via a resistor) to the Arduino's Digital Pin 2 - this is active high.
* This DE pin is also connected to the chip's RE bar (receiver enable) pin (2) and therefore controlled by the Arduino's Digital pin 2 too - this is active low.
* Arduino Digital Pin 2 = Rx/Tx 'Enable'; High to Transmit, Low to Receive
* So, to transmit data from Arduino Digital Pin 1 you need to take Digital pin 2 high, and to receive data to Arduino Digital Pin 0 you need to take Arduino Digital pin 2 low.
Sample Code：
RS485 Transmit Data
int EN = 2; //RS485 has a enable/disable pin to transmit or receive data. Arduino Digital Pin 2 = Rx/Tx 'Enable'; High to Transmit, Low to Receive
void setup()
{
pinMode(EN, OUTPUT);
Serial.begin(19200);
}
void loop()
{
// send data
digitalWrite(EN, HIGH);//Enable data transmit
Serial.print('A');
delay(1000);
}
RS485 Receiving Data
int ledPin = 13;
int EN = 2;
int val;
void setup()
{
pinMode(ledPin, OUTPUT);
pinMode(EN, OUTPUT);
Serial.begin(19200);
}
void loop()
{
// receive data
digitalWrite(EN, LOW);//Enable Receiving Data
val = Serial.read();
if (-1 != val) {
if ('A' == val) {
digitalWrite(ledPin, HIGH);
delay(500);
digitalWrite(ledPin, LOW);
delay(500);
}
}
}
