swift - TI SensorTag 2 CC2650 Servis Calculations (IR temperature - MPU9250) -


how can calculate ir temperature in cc2650.

ti temperature : f000aa00-0451-4000-b000-000000000000

temperature data: f000aa01-0451-4000-b000-000000000000

i try calculate object , ambient based on data in temperature data characteristic. object data higher ir temperature showed in ti application.

swift code:

 static func calculateobjectandambient(objectraw:int16, ambientraw:int16) -> (double, double)     {         let ambient = double(ambientraw)/128.0;         let vobj2 = double(objectraw)*0.00000015625;         let tdie2 = ambient + 273.15;         let s0 = 6.4*pow(10,-14);         let a1 = 1.75*pow(10,-3);         let a2 = -1.678*pow(10,-5);         let b0 = -2.94*pow(10,-5);         let b1 = -5.7*pow(10,-7);         let b2 = 4.63*pow(10,-9);         let c2 = 13.4;         let tref = 298.15;         let s = s0*(1+a1*(tdie2 - tref)+a2*pow((tdie2 - tref),2));         let vos = b0 + b1*(tdie2 - tref) + b2*pow((tdie2 - tref),2);         let fobj = (vobj2 - vos) + c2*pow((vobj2 - vos),2);         let object = pow(pow(tdie2,4) + (fobj/s),0.25) - 273.15;         return (object, ambient)     }

i want calculate mpu9250service data.

service = "f000aa80-0451-4000-b000-000000000000"

characteristic data = "f000aa81-0451-4000-b000-000000000000"

characteristic config = "f000aa82-0451-4000-b000-000000000000"

is there manual ? access gyro., accel., magn., data.

sorry english.

thank in advance.

calculation of object , ambient changed in cc2650.

so new swift calculations in here if needed;

   static func calculateobjectandambient(objectraw:int16, ambientraw:int16) -> (double, double)     {         let scale_lsb = 0.03125;         let = objectraw >> 2;         let obj = double(a) * scale_lsb          let b = ambientraw >> 2;         let amb = double(b) * scale_lsb         return (obj, amb)    }

resizing Telegram inline keyboard -

telegram's inline keyboard great feature lots of different use cases. inline buttons added list of items this: inline_keyboard = [[inlinekeyboardbutton(text="button", callback_data="button"), inlinekeyboardbutton(text="reset",callback_data="reset")]] inline_keyboard_markup = inlinekeyboardmarkup(inline_keyboard) update.message.reply_text("hi", reply_markup=inline_keyboard_markup) the above code adds 2 buttons each half width of chat screen. i know the normal keyboard button there resize_keyboard parameter somehow can used. my question is there way resize inline buttons ? example make full width or quarter width. unfortunately, can't now. :( you can suggest @botsupport , might add feature next version.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
