hexadecimal values to gray scale image

[muks]

I am getting hexadeciaml values in my comport.i am building the array and using reshape array function to convert it into a 2d array.I want to convert this into an gray scale image.I am using array to image conversion function.But i since i need a gray scale image i am giving the reference image as a gray scale image for the "array to image" function.I am getting an image but couldnt make out anything.I am sure that i am transmitting the bits correctly.i am not very sure if my mapping technique is correct.So my scale should be 0 to 255 but i am getting values from 00 to ff.Should i use some conversion function inbetween?

Hi muks,

if you have a numeric array, then it don´t cares, because it is only a view. Can you upload your vi with your picture data?

Hi muks,

it seems like the order is not correct. Can you give more information? Where does the image come from? Can you show the part of code from serial read to array?

Please check the VI.

Hi muks,

i don´t  know which format your data has, so it´s difficult to say what´s wrong. Maybe you mixed up rows and columns at the reshape function. I recommend to use an U8 array do store your received data.
