DS2413 'clone' has family ID of 0x85 - Raspberry Pi Forums

-

hi, i'm new here, forgive me if wrong place put forward suggestion. there plethora of stockists in china selling purports ds2413.(1-wire 2-way switch) package marked 3a 2100h. however, on using pi, not function, not have ds2413 family code of 0x3a, family code of 0x85. buyers have tried money back, vendors adamant ic performs correctly - , large part correct. running test on arduino , substituting 0x85 family code, devices work perfectly. change easy implement on arduino, of nightmare beginners on raspberry pi. - suggestion either: supply updated family group slave designation 3a 2100h device in next kernel distro; or provide sufficient information quick , easy change relevant module(s) pi users can make use of competitively-priced product. patience appreciated.

an update. yes 'clone' works pi. quick , (very) dirty hack allowed me access chip's registers via arcane file i/o supplied w1 subsystem. viewed w1_ds2413.ko object file using hex editor. there 3 entries of 0x3a in file, 2 of belong embedded text. (0x3a of course ':') re-wrote other 0x85 , saved file. having re-booted system, device directory (begins 85-) contained both 'state' , 'output' files, former readable, latter writable. wiring led device able control it.
2 things here: make backup of object file before edit it, in case of finger trouble. prepared use quirky file i/o interface access device. [i tested cp using source , destination files in home/pi directory.
forward 'correct' solution problem.

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
