Speed ​​of serial communication

Hi all 1-I am looking for a function or method faster than the function (Serial.readStringUntil ('\ r') or Serial.parseInt ()). I think two functions took a long time(+6ms) for receiver (4 int) same time. The program I used int m_1,m_2,m_3,m_4; //// m=[1000 2000] String inString = ""; void setup() {...

Re: How to synchronize the serial port of ESP32 Dual Core

thank you for the answer.
I use Xbee for transmission
the function that I used (in reception Serial.readStringUntil('\r')

the problem:

prog loop time (5ms) insufficient for transmission (6 Int variables) and reception (4 Int variables) on a core, it can not process this data in a loop <5 ms.

Re: How to synchronize the serial port of ESP32 Dual Core

Tx and Rx same speed( baud rate).
insufficient loop time (4 ms)for transmitted (6 Int variable) and receive (4 Int variable) in a Core.
can we share the communication between two core, core==>reception, core==>transmission with synchronization.

How to synchronize the serial port of ESP32 Dual Core

I have a serial communication problem, because a core does not support transmitting (TX) and receiving (RX) 5 variable in bouck time at 4ms / 5ms.
Is it possible to do two port synchronization serial1> (RX) in core1 and port serial2> (TX) in core 2.
thanck.

how To use the LEDC/PWM functions

can we use the function "" ledc_timer_config() "" on arduino ;because the function" ledcSetup " does not give access for the timer choice (timer1, .... or speed_mode).
I want to generate 4 pwm per timer.
can you help me .
