Hi guys, its anybody out there who has working Ultrasonic ranging module ( HC-SR04 ) ? Im using bi-directional lvl shifter (3,3V< - >5V), between Udoo and sensor. After upload .ino sketch, its all time returned "Out of range" on my serial. I tried it with two or more examples, but result was same. I thing its could be problem of pulseIN() function on Arduino Due -> https://github.com/arduino/Arduino/issues/1309 But i cant confirm it, because i have a lack of knowledge with this. Can someone help me? I like Udoo, but this little things make me crazy .. Thank you and have a nice day
We used them to realize a couple of projects. You can take a look at the Smart Theremin we did: http://www.hackster.io/mikelangeloz/udoo-theremin http://www.hackster.io/mikelangeloz/udoo-smart-theremin
when i verify the code i get this error Arduino: 0158 (Linux), Board: "Arduino Due (Programming Port)" /home/ubuntu/Arduino/libraries/NewPing/NewPing.cpp: In constructor 'NewPing::NewPing(uint8_t, uint8_t, unsigned int)': /home/ubuntu/Arduino/libraries/NewPing/NewPing.cpp:21:17: error: cannot convert 'RwReg* {aka volatile long unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment _triggerOutput = portOutputRegister(digitalPinToPort(trigger_pin)); // Get the output port register for the trigger pin. ^ /home/ubuntu/Arduino/libraries/NewPing/NewPing.cpp:22:13: error: cannot convert 'RoReg* {aka volatile long unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment _echoInput = portInputRegister(digitalPinToPort(echo_pin)); // Get the input port register for the echo pin. ^ /home/ubuntu/Arduino/libraries/NewPing/NewPing.cpp:24:75: error: 'portModeRegister' was not declared in this scope _triggerMode = (uint8_t *) portModeRegister(digitalPinToPort(trigger_pin)); // Get the port mode register for the trigger pin. ^ Error compiling.
