Alternative SoftwareSerial in Arduino. CustomSoftwareSerial library allow to configure and custom Parity Bit and Stop Bit.

customsoftwareserial's Issues

serial.begin suporte speed of 110

missing .Listen

Missing .Listen function. SoftwareSerial use this to handle 2 ports. With customSoftwareSerial i cant use with 2 ports. can you help? what is to do?

modbus and customSoftwareSerial

Hi
wanted to use this with Modbus

but got an error

Did I miss anything:

Does not work for 100000 baud rate

Hi, would you be able to help me set the delay array data for a baud rate of 100000?

Thanks!

CustomSoftwareSerial for ESP8266 / ESP32

How can I use this bibliotheque for ESP8266 & ESP32 ?

Garbage @ 115200

First of all, I wanted to thank you for the library, very helpful. It is unbelievable that Arduino has so many constraints in terms of communication.

Right now, I'm using your library, but I'm having troubles with the baudrate. I can only have good data a 9600 bps. Changing to 115200 everything is just garbage. Unfortunately, my application does not allow something less that 115200 bps. In order to test the library, I did the following program. The following code uses the default pins (0,1) to transmit the word "Hello world". But I only get reliable data at 9600. Any answer will be much appreciated it.

#include <CustomSoftwareSerial.h>
CustomSoftwareSerial* customSerial;               // Declare serial
CustomSoftwareSerial* customSerial1;


//#include <SoftwareSerial.h>
#include <stdint.h>

//SoftwareSerial portOne(10, 11); // RX, TX

unsigned int read_val=0;
void setup() 
{
  //Serial.begin(115200);
  while (!Serial) 
  {
    ; // wait for serial port to connect. Needed for native USB port only
  }
  delay(10);

  customSerial = new CustomSoftwareSerial(10, 11); // rx, tx
  customSerial1 = new CustomSoftwareSerial(0, 1); // rx, tx
  customSerial1->begin(14400, CSERIAL_8N1);
  customSerial->begin(115200, CSERIAL_8N1);         // Baud rate: 9600, configuration: CSERIAL_8N1

  //portOne.begin(115200);
  delay(1000);
  //portOne.print(50,HEX);
  customSerial->print(50,HEX);
  customSerial1->print("Hello world");
}

void loop()
{
  while(true)
  {

    if (customSerial->available()) 
    {  
        read_val=customSerial->read();
        Serial.println(read_val);
        //Serial.println("Hello");  
     }  
   }  
 }

what values should I add to the table for operation at 10000 baud? (F_CPU=16 000 000)

problem with myserial->readBytes

Greetings, the problem I have is that in the connection to 9600 bit 7 even parity, it does not capture the data correctly, if you could help me with that, I would be grateful.

Porting for ESP8266?

Unknown code...

Hi
this variable is never used: uint8_t maxValueOfData
look at: CustomSoftwareSerial.cpp, Row:477:11
uint8_t maxValueOfData = round(pow(2, this->_numberOfDataBit - 1));
Thanks & Regards

To delay even parity bit without

507 writeParityBits(numberOfBits1);
508 tunedDelay(_tx_delay);
↓↓↓↓↓↓↓↓↓↓
507 writeParityBits(numberOfBits1);
508 if(this->_parityBit != NONE) {
509 tunedDelay(_tx_delay);
510 }
