Integrated Circuits - Raspberry Pi Forums

hi everyone:
sorry question because not question raspberry... well, not , @ same time..
using rpi arduino , got integrated circuit between them (74lvc2g53) (i don't want give details, simple mux/demux)
question why ic has 2 gnd?? :?: not know if has special function. not first time see ic more 1 gnd. can connect them same gnd? why didn't manufacturer himself?...
thank you!

if chip package has more pins logic needs, manufacturer assign them innocuous, , ground innocuous can get. since sockets (and packages fit them) come relatively few standard sizes, manufacturer has pick 1 has @ least enough pins circuit, having pins isn't surprising.

hello everyone, name kedi.. make system connecting raspberry pi 2 , arduino uno arduino adc of 1 dust sensor sharp gp2y1010au0f , 4 gas sensor. want show decision of air quality system in running text @ p10 16x32 led dot matrix display. in raspberry pi 2, connect p10 pins in gpio25, gpio12, gpio16, gpio13 & gpio26. now, i'm finish circuit , don't know must connect p10's vcc & ground (red & black wire). can me? , code in python controlling p10(1r)-v706 dot matrix?.. regards, kedi i can't python code (did mine in basic on risc os) regarding power, panels each require 2.5a, you'll need separate supply them. if attempted power them pi, pi's polyfuse blow immediately. alternatively, use supply capable of giving 10a supply both panels , pi. raspberrypi

hi, thank help. question simple: how convert raspistill data opencv processing. code: select all def capture(settings, width, height): command = "raspistill %s -w %s -h %s -t 200 -e bmp -n -o -" % (settings, width, height) imagedata = stringio.stringio() imagedata.write(subprocess.check_output(command, shell=true)) imagedata.seek(0) im = image.open(imagedata) buffer = im.load() imagedata.close() return im,buffer code: select all image1, buffer1 = capture(camerasettings, testwidth, testheight) cv2.imshow('image',image1) want use different opencv processing techniques, before need know doing wrong. bests svato raspberrypi
