Update on diozero - Java Device I/O library - Raspberry Pi Forums

-

almost ready 1.0 release, see https://github.com/mattjlewis/diozero details.
getting odd behaviour wiringpi, pi4j , jdk device i/o knocked pigpio jni wrapper library (there 1 partially implemented). preferred provider raspberry pi.
again understand overlap in functionality between , pi4j, in particular new device capabilities in v1.1-snapshot. stated wanted ensure maximum portability across devices present clean object-orientated api similar offered python gpio zero.

usage example:
1. controlling led button

code: select all

try (button b = new button(buttonpin, gpiopullupdown.pull_up); led led = new led(ledpin)) { 	b.whenpressed(led::on); 	b.whenreleased(led::off); 	logger.info("waiting 10s - *** press button connected pin {} ***", integer.valueof(buttonpin)); 	sleeputil.sleepseconds(10); }
2. doing same via mcp23017 gpio expansion board:

code: select all

try (mcp23017 mcp23017 = new mcp23017(intapin, intbpin)) { 	try (button button = new button(mcp23017, inputpin, gpiopullupdown.pull_up); 			led led = new led(mcp23017, outputpin, false, true)) { 		button.whenpressed(led::on); 		button.whenreleased(led::off); 		logger.debug("waiting 10s - *** press button connected mcp23017 pin {} ***", integer.valueof(inputpin)); 		sleeputil.sleepseconds(10); }
feedback welcome.

uploaded snapshot build maven repository - newest addition support mcp30/32/34 adcs ws281x / neopixel leds (via jni wrapper around rpi_ws281x library).
working on documentation @ http://rtd.diozero.com.

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem

LED Strip Code

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
