hello, i working on project need store bitmaps on arduino's flash memory. have been looking progmem libraries finding ways save strings , primitive data types. have been thinking of using byte arrays display image need images display in full colour on tft display. is possible save images on flash memory? thanks i'm pretty sure impossible nature of atmega. sd card shield or module. besides, code take decent portion of 32k or memory, leaving little image assuming it's possible.

hi there, i'm building system used remotely , 1 of requirements our pi 3 able turn on our nvidia jetson tx2 dev kit in event shuts down. we're shorting power pins on jetson , works fine on jetson's end, having hard time getting of pins on our rpi 3 switch transistor ( http://pdf1.alldatasheet.com/datasheet- ... 123ap.html ) we're using off, can short power pins on jetson needed gpio on pi when doesn't receive ping jetson. suggestions or roadmap appreciated. thanks i don't understand. when " shorting power pins" mean connecting positive supply directly ground? sounds bad idea. datasheet linked not transistor. it's integrated circuit "charge control, monitoring 2, 3, 4 or 5 series supercapacitors" suspect simplest solution might relay module. http://www.instructables.com/id/control ... pi-and-a-/ raspberrypi

bonjour, jusqu'ici, j'ai effectué tous mes montages sur plaque d'essai, mais je souhaites maintenant les faire de façon plus solide. exemple: je veux mettre un montage dans une boite, cette boite va bouger, tomber, voler .. etc. les connectiques vont très facilement se débrancher sur une plaque d'essais, comment y remédier ? avec ce type de câble , on ne peut pas résoudre le problème ? cordialement quote avec ce type de câble on ne peut pas résoudre le problème ? sûrement pas. mon point de vue : pas de carte uno mais une nano (c'est la même que la uno en format plus petit et à connectique à souder) une carte pastillée un fer à souder aucun câble enfiché, acceptable bornier à vis.

i have gsm arduino sensor hook sleeps 15 minutes before uploading data database. want turn off overnight , considering using external clock or light sensor, figured gsm module has it's own ability check time. do of have easy way keep track of time using atmega internal cycles? problem being millis doesn't work while sleeping. i'm guessing i'll have keep track of number of sleep cycles (x 8s per cycle) + millis while arduino awake , use estimate time of day. that'll close enough, maybe every few days check , reset clock. or there i'm missing?

hola todos.... tengo un proyecto de refrigerador ( nevera para vinos ) con celdas peltier , sin embargo me veo un poco atrancado la hora de planificarlo con arduino : por un lado tengo el obvio sensor del interior de la nevera, un dht11 para medir temperatura y humedad de la habitación en que se encuentra la nevera, y otro (dallas ds18b20) para medir la temperatura de la zona caliente de la peltier (con idea de no tener todo el rato funcionando el ventilador de enfriado). un pulsador, un display 16x2 y un par de relés (peltier y ventiladores) terminan de configurar el hardware del proyecto. toda la comunicación está probada y todo funciona ok en un arduino nano . dicho lo cual, aquí el dilema que se me presenta. por un lado me parece un desproposito tener al arduino dando vueltas en su loop() como un loco para la simple tarea de termostato y visualizador de datos por pantalla que se le pide (solucion delay(10000) por ejemplo); por otro lado, puede recibir una pulsación para c...

i have solar charger (batteryminder brand) adopted use arduino project. despite claims, thing not weather resistant & board lasted short time.  well; of components lasted short time.  rust not our friend. 10 resistors & 2 diodes rusted thru @ 1 end.  resistors easy identify (except 1 2x thick rest); 2 diodes standard 14n148 type diodes (one bit bigger).  not provide me support or schematics; on own fix it. there couple other diodes on board looked healthy , similar sizes; unsoldered them test them transistor/component tester.  1 tested out  diode uf=789 , ir=4na; other tested uf=704, ir=10ua -- note able test 1st 1 repeatidly , got similar results; 2nd 1 fails diode , sub 1.5 ohm in 1 direction , .6ohm other... (so have 3 diodes need identify). is there way know / guess diode work w/o schematic? markings can't see w/o proper magnification?  iow: there way can replace these diodes ? my camera has dead batteries, i'll go buy if ...

hello, attempting turn pi, model yet chosen, simple plc using can bus protocol. wondering if pi supports can communication? also, planing on using c++ programing language execution speed. wondering if knows of libraries interpret can? ~ben the usual way use can controller (eg. mcp2515) connected spi interface pi. example : http://www.industrialberry.com/canberrydual-v2-1/ can bus supported in linux kernel socketcan , appears network interface. https://en.wikipedia.org/wiki/socketcan https://www.kernel.org/doc/documentatio ... ng/can.txt there test / debugging programs socketcan here : https://github.com/linux-can/can-utils there usb can interfaces available when last looked more expensive , intended used windows pc's. hope helps started. darren. raspberrypi

hi, i feel quite stupid. when log in newly installed joomla! installation on internet found following warning: following php server settings not optimal security , recommended change them: php register_globals setting `on` instead of `off` so, spring action, , @ globals.php change offending variable. find? define( 'rg_emulation', 0 ); i must severely mistaken. suggested http://help.joomla.org/component/option ... temid,268/ what doing wrong? michel these 2 different things: php register_globals and register_globals emulation it may require host shut off - may able .htaccess statements, perhaps not.

first, can't display settings save whenever restart computer. i'm using nvidia's x server. once got desired settings gui, did terminal save: sudo nvidia-xconfig , said did. although, when restart computer, i'm 1 monitor low resolution. missing something? i'm using 190.42 driver. flash movies stopped working in firefox. i'm running 64-bit ubuntu, , got adobe's new 64-bit flash plugin linux. , worked! randomly stopped working. did install copy libflashplayer.so firefox plugins directory. since worked awhile figured that's needed do. also, about lugins looks fine. shows flash enabled both swf , spl, , it's showing correct plugin version (10.0 r42). ideas? , appreciated! nvidia-xconfig reset xorg , nvidia-settings default. should have use when wrong. try running, code: gksu nvidia-settings and once have everythign configured, click "write configuratio...

hello everyone, i working on project need relatively accurate , consistent positioning dc motor. motor sent command of position go to, , power cut motor @ target position, motor has overshoot , goes past target. i found arduino pid library , attempted use fix overshoot, , seems helping some, i'm not sure if i'm using properly. below sample of code of how i'm using it: code: [select] void leftfifteen() {       //checks see if window way or stopped in middle   midupcheck();   targetl = 167; //this desired position   if (!stopcheck(serialdata1)) {         if(enccountl > targetl) { //if current position > target position       leftwindow.setcontrollerdirection(reverse);       leftwindow.compute();       serial.println(f("decreasing angle of left window 15"));       downleft(speedl); //tell motor move @ specifc speed , direction     ...

hi, below 2 set of codes. 1 using rtczero millis() while other using millis() only. seems former exhibits strange behaviour while latter behaves expected. doing wrong, or if rtc.getepoch() being called , disrupt millis() well? thanks. 1. rtczero , millis() #include <rtczero.h> #include <scheduler.h> rtczero rtc; unsigned long t0, t1;   void setup() {   serial.begin(115200);   while (!serial);     rtc.begin();   rtc.setepoch(1468456152); //some random epoch time   t0 = rtc.getepoch();   t1 = millis();   scheduler.startloop(loop2); } void loop() {    if ((millis() - t1) >= 500) {     serial.print(t0);     serial.print(f("."));     serial.println(t1);     t1 = millis();   }   yield();  } void loop2() {    if (rtc.getepoch() > t0) {     t0 = rtc.getepoch();   }   yield(); } result: 1468456155.1434 1468456157.1944 14...

hallo, ich bin neu in der arduino welt und kenne mich nur semipro mit der technik aus. mein vorhaben ist es ein drumset bestehend aus 5 piezo´s zu bauen. diese sollen via usb ein macbook geschlossen werden. die 5  piezos möchte ich in ableton frei belegen können um damit beispielsweise drums spielen zu können. nun ist die frage ob ein arduino uno alleine ausreicht? ich habe gelsesen das es shields gibt die irgendwie usb zu midi konvertieren? wie gesagt ich bin noch neu in dieser welt und habe weder von der programierung noch dem aufbau recht einen plan. ich habe bereits viel im internet geschaut und alles ich finde weißt immer darauf hin das ich ausser dem arduino uno noch weitere sachen brauche. kann mir jemand helfen? gruß aus hamburg marco hallo, ich bin kein großer musiker, aber ich denke es gibt das originale midi (mit dem runden stecker) und midi über usb. verstehe ich dich richtig, dein gerät soll als usb-midi gerät mac erscheinen ? dafür gibt ...
