c# - Connecting to Weight Scale through RS232 -


i have been cracking head trying figure how read weight scale, i'm kind of new c# , have never dealt com ports before, put code examples found online , other articles have been researching. i'm kind of stock, appreciate if there give me light of why code not displaying anything. scale i'm using nv-1.5r cci companies. i'm connecting trough rs232 port using db9 female female null modem cable. code have far:

using system;  using system.io.ports; using system.collections.generic;  namespace serialcombuffering { class program {     serialport com = new serialport(serialport.getportnames()[0],       9600, parity.none, 8, stopbits.one);     list<byte> bbuffer = new list<byte>();     string sbuffer = string.empty;      static void main(string[] args)     { new program(); }      program()     {         com.datareceived +=           new serialdatareceivedeventhandler(com_datareceived);         com.open();          console.writeline("waiting incoming data…");         console.readkey();     }      void com_datareceived(object sender,       serialdatareceivedeventargs e)     {         // use either binary or string technique (but not both)          // buffer , process binary data         while (com.bytestoread > 0)             bbuffer.add((byte)com.readbyte());         processbuffer(bbuffer);          // buffer string data         sbuffer += com.readexisting();         processbuffer(sbuffer);     }      private void processbuffer(string sbuffer)     {         console.writeline(bbuffer);         console.writeline(sbuffer);         console.readkey();     }      private void processbuffer(list<byte> bbuffer)     {         // in byte array useful information         // remove useful data buffer     } } }

i'm not sure else after this, hoping display , figure out there, whenever run literally nothing. nice if kind of guide me trough next. , appreciate collaboration before hand!

here's have related scale documentation enter image description here

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
