i work adobe phtoshop cs3, combine 2 images of same watch , use mask combinethem, lately whenever open 2 images, drag 1 onto other one, adobe phtoshop freezes. tried adding more memory computer... nothing. know why ? think it's teh program? or computer? could ram or scratch disk space. try resetting preferences first ( http://www.adobeforums.com/webx/.ef4a07f/1?14@@ ). make sure have enough free hard drive space on whatever drive have designated scratch drive. make sure memory allocated photoshop in preferences set 55%. if none of above works, post system specs , more detail.

note: mean not 2 rpi, mean ask more 2 rc522... (3.. 4.. 5... vs..) first of using mfrc522-python library... can use library to, main question ss pins. found this; need configure multiple ss pins, , other devices (rc-522) share same (mosi,miso , sda) can configure gpio pin ss pin? or ss pins must 22 , 24? , mean cannot connect multiple devices raspberry? (>=3) there's 2 spi interfaces on header https://pinout.xyz/pinout/spi gives 4 devices without having muck about. can "bit-bang" spi on set of 3 pins yourself. can use existing spi interface , gpio third chip select pin. doing needs updated device tree file. wire rc522s arduino, running spi sketch , use usb serial data arduino. use arduino , esp8266 or stand-alone esp8266 (not cheapo, crappo esp01) read spi data , send raspberry wifi. https://nodemcu.readthedocs.io/en/maste ... dules/spi/ depends how may readers need connect. raspberrypi

hi, i trying split serial data different character arrays , print, no success. following serial data: code: [select] @$25.99*$9.99*omega t-shirt (xxl)*omega101*# character '@' starting character. character '#' ending character. character '*' separator. trying split above in 4 character arrays. following program. code: [select] int seperatorcount = 1; char receiveddata; char r_price[10]; char o_price[10]; char product_name[40]; char sku[15]; void setup() {   serial.begin(9600);   delay(500); } void letsdisplay() {   serial.println(r_price);   serial.println(o_price);   serial.println(product_name);   serial.print('(');   serial.print(sku);   serial.println(')'); } void loop() {   int i,j,k,l = 0;   while (serial.available() > 0)   {     receiveddata = serial.read();     if (receiveddata == '@')       serial.println("\n________________...

ok guys, i'm sure knows how me. i'm trying build led ring cornhole set , i'm having bit of trouble. i'm using atmel 32u4 clone running @ measured 4.6v off usb port on pc. have 4 2812b leds in string. have data pin pin 6, 5v right off usb connector. using neopixel library. when program micro leds work perfectly. bow were. after board programmed , unplug , plug in first led white , other 3 off. have verified program still running via printscreen. trouble shooting: - tried 220ohm , 470ohm resistor on data pin - used diode on input power. - lowered brightness setting. - added 1sec delay startup. i same results every time. for fun of pulled out due had laying around , runs string perfectly. though noticed due seems have boost converter in gets 5v above 5v not under it. can power cycle want , no problem. i've read leds should work @ 4.6v volts. have tried running off different pin ? so, after first white led, run expected ? example pin flash...

greetings, i have created soil moisture monitor prototype using standard arduino, powered 5v usb charger, rgb led indicating moisture content!  might simple, first arduino project, , i'm excited it.  i take project next level, , make battery powered.  use advice guide me on creating works well, , has decent battery life. here things i've been thinking about: i want use pro mini project because of small footprint , because have 1 on hand i want use type of led provide alert plant needs watered.  realize solid led not ideal, , drain battery quickly.  thinking maybe using rgb led blink different colors.  have blink 5 times once minute provide feedback plant keeper. i want battery powered.  know 9v batteries not recommended, thinking using 4xaa batteries, on/off switch in order prolong sensor life, , increase battery life, use 1 of digital pins turn soil moisture sensor on/off before/after reading sensor every 30 minutes. i've been re...

hi, i check tv lift using infrared signals dc motors. when control signal bottom , moving or down depending on state of overlying limit switches. sending signal open while moving tv. tv's remote control when press power button repeatedly produce 2 different codes both code "or" have written form. when press program power working correctly, when comes different signals remote control (volume , down, changing channels, etc.) hangs. think i'm doing loop error. furthermore, when motor in motion again when send switch control signal stopped moving again in opposite direction. please me. my code follows: #include <irremote.h> int recv_pin = 11; int move_up = 8; int move_down = 9; int top_sw = 6; int bottom_sw = 7; irrecv irrecv(recv_pin); irsend irsend; decode_results results; void setup() { irrecv.enableirin(); pinmode(move_down,output); pinmode(move_up,output); pinmode(top_sw,input); pinmode(bottom_sw,input);   serial.begin(9600); } void loop() { ...

i (and 200 others) have been using openvg graphics on headless rpi running jessie lite touchscreen control digital amateur television transmitter year or so. realise sooner or later going have migrate stretch , have started testing. can't seem find components need openvg in either desktop or lite versions of stretch (we end using lite version). 1 cause of problem appears libopenvg.so , number of other files not included in /opt/vc/lib/. means when come compile errors such : code: select all libshapes.o: in function `loadfont': libshapes.c:(.text+0x1c0): undefined reference `vgcreatepath' libshapes.c:(.text+0x1e4): undefined reference `vgappendpathdata' have changed makefile use -lbrcmegl -lbrcmglesv2 rather -legl , -lglesv2 there package can load install openvg library files? or missing else obvious? suggestions dave project lead portsdown datv transmitter: https://github.com/britishamateurtelevisionclub/rpidatv small tips on how solve similar problems...
