HX711 - Power & Logic lines question

-

hello,

i using 3.3 voltage chip interface hx711 chip, power hx711 chip 5 volts. have looked @ data lines coming out using multimeter , doesn't seem go above 3.3 volts it's hard tell digital multimeter.

on datasheet see 100 resistors on data lines.

my question guys think device safe communicate 3.3 volt system?

here datasheet: http://www.dfrobot.com/image/data/sen0160/hx711_english.pdf

thanks help,

cameron.

according datasheet, dvdd connected same power supply mcu.

thus, if applying 5v dvdd, using 3.3v mcu, using in manner contrary manufacturers specifications, , shouldn't that.

under power supply options, states avdd, analog supply voltage, can higher dvdd, , vise versa.

so...
you should able use it, you've got have 5v on avdd , 3.3v mcu power supply on dvdd. sure you've wired else right, of course - read "power supply options" section in data sheet.

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
