(SofwaareSerial comunication)invalid conversion from 'int' to 'SoftwareSerialConfig' [-fpermissive]

[ridhoazhar313]

hi there,all...in this project i use ESP32 as receiver data from uno.here,i am using RX,TX in ESP32 at pin 16 and 17 and make it global .but i want calling it in another finction but by its inilitation name.i try to use SofwareSerial and declare at pin 16(Rx),and (17(Tx). and sudenly this problem happen.how to solve this?.........i think there is no mistake when i declare UART pin with SofwareSerial.

this is my code:

//#define RXp2 16
//#define TXp2 17
#include <WiFi.h>
#include <SoftwareSerial.h>
// membaca pinout RX,Tx
SoftwareSerial Seriala2(16, 17);

in this line

begin (9600, SERIAL_8N1, 16, 17);

may be you want SWSERIAL_8N1 instead

[UKHeliBob]

The ESP32 has more than one Serial interface so do you really need to use SoftwareSerial ?

[ruilviana]

@ridhoazhar313

Seriala2.begin (9600, SERIAL_8N1, 16, 17);

The serial config is limited to 8N1.
ref:

SoftwareSerial limitations - no bit-size, parity, or stop bits

The document for SofwareSerial should mention in the "Limitations" section that serial config is limited to 8N1. I'd like to see the SoftwareSerial library extended to support an overloaded begin() method with a second "config" parameter so that I could pass it something like mySerial.begin(1200, SERIAL_7E1), but until such time as that is implemented, the limitation should be noted in the documentation.

@ruilviana

The serial config is limited to 8N1

that's not applicable for EspSoftwareSerial which @ridhoazhar313 is using

SoftwareSerialConfig and parity

The configuration of the data stream is done via a SoftwareSerialConfig argument to begin(). Word lengths can be set to between 5 and 8 bits, parity can be N(one), O(dd) or E(ven) and 1 or 2 stop bits can be used. The default isSWSERIAL_8N1 using 8 bits, no parity and 1 stop bit but any combination can be used, e.g. SWSERIAL_7E2. If using EVEN or ODD parity, any parity errors can be detected with the readParity() and parityEven() or parityOdd() functions respectively. Note that the result of readParity() always applies to the preceding read() or peek() call, and is undefined if they report no data or an error.

To allow flexible 9-bit and data/addressing protocols, the additional parity modes MARK and SPACE are also available. Furthermore, the parity mode can be individually set in each call to write().

This allows a simple implementation of protocols where the parity bit is used to distinguish between data and addresses/commands ("9-bit" protocols). First set up SoftwareSerial with parity mode SPACE, e.g. SWSERIAL_8S1. This will add a parity bit to every byte sent, setting it to logical zero (SPACE parity).

To detect incoming bytes with the parity bit set (MARK parity), use the readParity() function. To send a byte with the parity bit set, just add MARK as the second argument when writing, e.g. write(ch, SWSERIAL_PARITY_MARK).

that being said, yes, 100% in favour of going to hardware serial if it's available

@J-M-L
tks

[david_2018]

Just to point out the actual problem, in case someone did not notice from post #5, with the esp8266 version of SoftwareSerial, the correct term for the call to begin() is SWSERIAL_8N1, not SERIAL_8N1.

[J-M-L]

@david_2018

in case someone did not notice from post #5

I proposed this in the first answer...

@J-M-L

may be you want SWSERIAL_8N1 instead

[david_2018]

Oops, sorry I missed that since there was so much discussion afterwards.

[J-M-L]

it's OK, it seems @ridhoazhar313 missed it too
