In this case you just want to access the data register itself. PORTB and PORTD registers contain the pin data you are looking for. I finally got access to an Arduino to figure it out. You want to use bitRead(PORTD, pin). Serial.println(bitRead(PORTD,3)); //Reads bit 3 of register PORTD which contains the current state (high/low) of … Read more
In the Arduino software: go to File -> Preferences and then select Show verbose output during -> compilation. Finally, when you are compiling, the program will show you lots of data. At the last lines, you will find the path1 to the .hex file. 1Every time the path changes!
Another possible reason for this error for the Mega 2560 is if your code has three exclamation marks in a row. Perhaps in a recently added string. 3 bang marks in a row causes the Mega 2560 bootloader to go into Monitor mode from which it can not finish programming. “!!!” <— breaks Mega 2560 … Read more
chdmod works for my under debian (proxmox): # chmod a+rw /dev/ttyACM0 For installing arduino IDE: # apt-get install arduino arduino-core arduino-mk Add the user to dialout group: # gpasswd -a user dialout Restart Linux. Try with the File > Examples > 01.Basic > Blink, change the 2 delays to delay(60) and click the upload button … Read more
This is how I solved the problem. In Device Manager you will find the Arduino COM port. Go to the Advanced properties of the port Set the COM port number to COM1. Then replug the USB.
Unlimited string readed: String content = “”; char character; while(Serial.available()) { character = Serial.read(); content.concat(character); } if (content != “”) { Serial.println(content); }
Go to your Arduino documents directory; inside you will find a directory named “Libraries”. The imported library directory will be there. Just delete it and restart the Arduino app. Your Arduino library folder should look like this (on Windows): My Documents\Arduino\libraries\ArduinoParty\ArduinoParty.cpp My Documents\Arduino\libraries\ArduinoParty\ArduinoParty.h My Documents\Arduino\libraries\ArduinoParty\examples …. or like this (on Mac and Linux): Documents/Arduino/libraries/ArduinoParty/ArduinoParty.cpp Documents/Arduino/libraries/ArduinoParty/ArduinoParty.h … Read more
Use like this: String myString = String(n); You can find more examples here.
I had this problem with a Crowduino, running the Arduino IDE on OS X. The solution for me was to switch on verbose output during upload (in the Arduino IDE preferences pane). Then, when uploading, you can see AVRDUDE sending three packets avrdude: Send: 0 [30] [20] (with corresponding RX flashes on the board) right before … Read more
