问题 Here is my while main loop void loop () { s4state = digitalRead(11); //Lit pin 11 switch if (s4state == 1) { // wargning/detrese detresse(1); } if (s4state == 0) { // wargning/detrese detresse(0); } } And here is the function I want to call. void detresse(int valeurPin) { while(1==valeurPin) { digitalWrite (2, HIGH) ; digitalWrite (3, HIGH) ; digitalWrite (4, HIGH) ; digitalWrite (5, HIGH) ; digitalWrite (6, HIGH) ; digitalWrite (7, HIGH) ; delay (500) ; digitalWrite (2, LOW) ; digitalWrite

Struct received over COM port from Arduino has incorrect values in some but not all of its fields

问题 I want to send some serial values to my PC. Arduino with sensors (master) >> via Bluetooth >> Arduino (slave) >> via serial com port >> PC with C# app Serial transmission works well from master to slave, but how can I receive and convert the values received to floats on the PC side using C#? Slave code is: Struct definition typedef struct { char bt1; float bt2; float bt3; float bt4; float bt5; float bt6; float bt7; char bt8; } PayloadBT; PayloadBT payloadBT; Struct sent to pc BT_writeAnything

safe and fast method for communicating a mix list of integers and booleans between pyserial and Arduino

问题 I want to send and receive a mix list of integers and booleans between pyserial and an Arduino. I have figured the Arduino to pyserial out, well partly: Arduino code: ... bool var1 = ...; int var2 = ...; ... void setup() { ... Serial.begin(9600); ... } void loop() { ... // here I send the data in CSV format Serial.print(var1); Serial.print(", "); Serial.print(var2); Serial.print(", "); ... Serial.println(var_n); ... } and the pyserial side: import serial serPort = serial.Serial("COM7")

Serial communication between pc and Arduino through USB

问题 I have some C++ code that I need to use for serial communication between PC and Arduino. The file "Serial.cpp" is including a file called "stdafx.h" that doesn't exist in the project or anywhere on my computer, which obviously causes an error. Other than that, I also get other errors, such as C2065 'CSerial': undeclared identifier . Here are the three files that are in the project: Serial.h #ifndef __SERIAL_H__ #define __SERIAL_H__ #pragma once #include <Windows.h> #include <memory.h> #define

Problems with connecting HC-05 Bluetooth module to PC

问题 So i've been trying to connect my HC-05 BT module to PC. I'm sure i connected everything correct, i'm not new with arduino stuff. What i try to do now is i want to communicate with arduino using uart connection via BT. I have arduino leonardo, and here is my code: void setup() { Serial1.begin(9600); pinMode(LED_BUILTIN, OUTPUT); } void loop() { if (Serial1.available()>0) { String ainfo; ainfo = Serial1.readStringUntil('\n'); if (ainfo.equals("ON")) { digitalWrite(LED_BUILTIN, HIGH); Serial1

Java rxtx code to connect to rfcomm0 is not working

由 纵饮孤独 提交于 2020-01-16 01:54:25
问题 I have successfully connected my arduino uno R3 with bluetooth mate module and am able to send data to my laptop running Ubuntu 12.04 via bluetooth. (using serial port protocol). The data is received on rfcomm0. The following code displays the received data : sudo screen /dev/rfcomm0 Now I am facing problems in reading this data in a java program. I have referred the code from http://playground.arduino.cc/Interfacing/Java. This uses the rxtx library to access the serial port. Here is the code

Arduino - Optimising existing method for iterating through an array

问题 Is there a more efficient and cleaner way of doing what the following method is already doing? void sendCode(prog_uint16_t inArray[], int nLimit) { unsigned int arr[nLimit]; unsigned int c; int index = 0; while ((c = pgm_read_word(inArray++))) { arr[index] = c; index++; } for (int i = 0; i < nLimit; i=i+2) { delayMicroseconds(arr[i]); pulseIR(arr[i+1]); } } This is in reference to an existing question I had answered. Arduino - Iterate through C array efficiently 回答1: There should be no need
