ASCII to decimal conversion function

[altenbach]

So what kind of problems are you encountering if you try to wire it as shown? it should work just fine.

You can either use "string to byte array" or typecast it to an array of U8. Same difference.

after conversion i will use that number for comparison of a range like

0 to 100 ===> sensor 1 data

101 to 200===> sensor 2 data

201 to 255 ==> sensor 3 data

and then it will be sent to a sensor gauge for display.

It seems you are now talking about a completely new problem instead of answering my last question. 😮

Can we assume that you solved the original issue? 😉

To select depending on the value range, you can wire the number to a case structure and define three cases according to the desired ranges.

Hi ehsa,

try the attachment. Type any char into ASCII string control...

[ehsanelahimirza]

i am attaching my VI.

you can see it and will syrely understand what i need.

 i want my converted number to connect to the node which is below waveform chart. ( where string to decimal number converter is attached). if i attach converted U8 array to it then there is an error because my comparison is based upon number whereas output of conversion is array

[ehsanelahimirza]

in my VI i dont require, " Make selection"  loop. if there is some lack in my explanation then plz do tell me. i will be really thankfull for help.

thanks

Hi ehsa,

"you surely understand" - no, we can't! You only ask (new) questions, but don't provide answers to our questions...

As you have been asked before: provide some sample data you're receiving from the serial port! When we see actual samples we can pin down how to convert those "ASCII bytes"!

Is the char that you get from the U8 conversion not ok?

ok, sorry for that

my actual data is only one byte. it gives 256 values.

here i am providing serial data scheme of my project

i am receiving data from 3 sensors in a controller.

that controller reads temperature sensor data and sends to serial using value of 1 byte (0 to100)

humidity sensor (101 to 200)

pressure sensor (201 to 255)

my all bytes will be (in bits) ( 00000000 to 11111111) == 0 to 255

Hi ehsa,

when all you get from serial port is just one byte then take that one single byte you get after the U8 conversion (& index array) operation. It's all you need!

[ehsanelahimirza]

after receiving data in single byte i will check it from which sensor it is and then i will send it to front panel display of that sensor.

there i am also checking limits of this data i.e. if i need temperature to 050 only then after receiving data >50 and <101 will send a constant to serial out.

if i am not clear still then plz plz ask me where i am not clear in explanation.

thanks very much
