How to send float through serial port in c#? -


this question has answer here:

i have 2 float now,say f1 , f2. want send them micro controller through computer serial port, how should it? understanding need convert f1 , f2 binary first,then send micro, after cnvert float again. confused how convert float binary before send them out? code 

    b1 = system.bitconverter.getbytes(f1);     b2 = system.bitconverter.getbytes(f2);

it depends on endianness of microcontroller's architecture. speaking need this:

  1. convert float 4-byte array. you're on right track, although c# rusty.
  2. send them 1 one microcontroller

  3. if microcontroller supports floating point representation cast four-byte array float:

    byte array[4]; // pre-allocate array getbytesfromserial(array); // fill array values serial port float converted = 0; memcpy(&converted, array, 4); /** "converted" holds float value */

now work if endianness of uc consistent order in sending data. if doesn't work try sending byte array in inverted order. , please mind error checking!

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
