microcontroller - Arduino Leonardo OR Uno for a pototype solenoid project ?? -

-

i software developer no prior experience in embedded programming. have develop prototype project:(example) generate morse code pulses output through solenoid in form of vibrations. found either arduino nano or micro job. though have choosen uno project keeping in view later requiremenst evolve.

i found leonardo & uno 2 close varianst. selected uno based on research did. learned leonardo not choice beginners due of problems and/or features. uno has more available being seasoned variant.

it nice if can have opinion it.

as , keshav saharia said, assuming capabilities of uno , leonardo both meet needs, reason choose uno because older, more mature, , better supported. example, of arduino posts here , on ee.se either based on uno or compatible uno. likewise, of arduino guides work out-of-the-box uno, not leonardo; leonardo 1 of footnotes: if have leonardo, need this other thing instead.

also, if, @ point, decide ditch arduino , use bare atmega chip, atmega328, mpu in uno 1 use, , 1 more people familiar with. leonardo uses different avr chip, atmega32u4, which, leonardo, not quite popular (widespread?). these reasons choose uno, far concerned.

on other hand, if hoping keep prototype board yourself, might want think leonardo, since more powerful: more io, second hardware serial port, etc.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

Image
i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
