I am trying to control the 485 relay using the 485 to ttl converter. I implemented it on arduino using the following code:
#include<SoftwareSerial.h>
#define SoftSerial_RX 10
#define SoftSerial_TX 11
SoftwareSerial RS485Serial (SoftSerial_RX, SoftSerial_TX);
byte DeviceID = 0x01;
// ON/OFF Relay
/* {1:deviceId,
2:"Write Single Coil" function,
3,4: coil address,
5,6: output value,
7,8: Cyclic Redundancy Check for error detection}*/
byte ON_RELAY1[8] = {DeviceID, 0x05, 0x00, 0x00, 0xFF, 0x00, 0x8C, 0x3A};
byte OFF_RELAY1[8] = {DeviceID, 0x05, 0x00, 0x00, 0x00, 0x00, 0xCD, 0xCA};
byte ON_RELAY2[8] = {DeviceID, 0x05, 0x00, 0x01, 0xFF, 0x00, 0xDD, 0xFA};
byte OFF_RELAY2[8] = {DeviceID, 0x05, 0x00, 0x01, 0x00, 0x00, 0x9C, 0x0A};
void setup() {
Serial.begin(9600);
RS485Serial.begin(9600);
pinMode(4, OUTPUT);
}
void loop() {
RS485Serial.write(ON_RELAY1, 8);
digitalWrite(4, HIGH);
delay(500);
RS485Serial.write(ON_RELAY2, 8);
delay(500);
RS485Serial.write(OFF_RELAY1, 8);
delay(500);
RS485Serial.write(OFF_RELAY2, 8);
delay(500);
}
Now, I want to implement the same using nRF52dk 52832. But I am not able to write the parallel code. Have any of you done anything similar?
Thanks in advance.
