Big number converter This service allows you to convert big positive integer numbers into binary, decimal, hexadecimal or base64 encoding schemes. The big number bitsize is also calculated. For example: The following hexadecimal big number converted into a decimal encoding scheme: b5 6c 4f ee ef 1b 04 5d be 70 4a d8 55 1d 8a 77 0d c1 45 00 f5 3b 1a 10 dd d7 f7 bb 7a 65 54 7f 60 d2 16 bb bd 12 a5 78 78 d6 b3 50 4e ba 17 48 27 7a 22 6f 2a 7c 1d a2 36 22 d8 59 a2 ae 3a 0b d4 d2 1b 8a 0e 5a 89 a9 e4 9a ff db 3f 04 e2 9b 75 c1 8d c5 8c 05 a1 f3 b5 92 5e a1 44 49 19 e4 90 b4 e9 ef e4 5d b2 20 6d f9 23 76 b8 b2 d4 af a3 06 f5 9e 03 8f b8 82 05 21 11 25 44 3a 80 05. Looks like: 432776809221. And its bit size is: 1024 Input big number converter: Enter a big number.: Number is a.: Convert number to a.:. = required.
After taking a quick look at some of the topics the Original Poster started it seems that the OP may be using MPLABX installed on a Linux OS and using the XC8 compiler for the PIC18F family of controllers. The question the OP asked is about the conversion of numeric values to be displayed in some human readable form.
In most cases this involves range limits, scaling and offsets. When using an Analog to Digital Converter there are range limitations imposed by the ADC having a finite number of bits of resolution. For most PIC18F parts this will be 8-bits, 10-bits or 12-bits. There are a few PIC18F parts with 16-bit ADCs. The OP states: 'I have Binary data on the port. I have used ADC to convert the temperature data and displayed it on the port.'

Complex Number Calculations.. Where they are actually used to change the calculator setup. You cannot use scientific functions in binary, octal, decimal,. The type of battery you should use depends on the model number.
This suggests that the sensor provides an analog output voltage that represent the temperature. It is usual for temperature sensors to provide a low voltage for colder temperatures and a higher voltage for warmer temperatures.
This means that an ADC reading of ZERO will be the coldest temperature the system can sense and an ADC reading of all ONES will represent the warmest temperature the system can sense. What the OP will need to do is to calibrate the system by using a reference thermometer to measure the actual temperature when the ADC readings are close to ZERO, call this T0, and close to all ONES call this T1. To convert the ADC readings to the same scale as the reference thermometer multiply the ADC reading by (T1-T0)/(ADC maximum count) then add T0 to the result. Note that the maximum count for an 8-bit ADC is 255, for a 10-bit ADC it is 1023, for a 12-bit it is 4095, also this calculation should use floating point arithmetic.
It is possible to do this with 32-bit signed arithmetic but is can get a bit tricky. Use C standard math and string library functions to convert the result to an ASCII string. The function sprintf can be used to do these kinds of formatting but it will bind in a lot of code so you run the risk of running out of code space for your application. If your PIC has a large amount of flash, more that 16K bytes, you should be fine using sprintf.
With experience you can understand the methods used to make the code that does this smaller and more efficient. Hi, Binary data is the native representation of integer data in a digital computer.
Hexadecimal or octal are representation for print or display that is easy to arrange. Converting binary integer to decimal digits is surprisingly cumbersome on a small 8 bit computer. Both sprintf and itoa functions, as suggested above, may be used. They will both use a few thousand instruction cycles to pick out 5 decimal digits from a 16 bit integer value. Last year, there was a long thread about more efficient algorithms for this conversion: There are alternative implementations for PIC16 devices, and for PIC18 devices which have a 8-bit hardware multiplier that is useful for this.
In this thread, inside the 'ThreePhaseVoltage' program: is: uBinDec.c with In there, assembly code for PIC16 and PIC18 devices, is inlined in C functions. It is used in connection with display on a alphanumeric LCD display. Regards, Mysil. Now it working there was a mistake in OpenADC, Both C18 and XC8 has a different prototype.
OpenADC(ADCFOSCRC & ADCRIGHTJUST & ADC12TAD, ADCCH1 & ADCINTOFF,ADCTRIGCTMU & ADCREFVDDVDD & ADCREFVDDVSS); Also, I have further question regarding converting. In my program I get output of ADC in 'out' variable. If I want to map it according to the temperature formula of a sensor than is it right? VOUT = TC. TA + V0°C here TC is 10 and V0°C is 500mV. TA = (VOUT-500mV)/10 In short, I should take one more variable TA (FLOAT) to store the temperature values?
Both floating point calculations, and integer division are slow and cumbersome operations on a 8 bit computer. With the sensivity of the temprature sensor 10mV per °C, calculating in integer millivolt may be convinient, and may avoid both floating point calculations and long division. Scaling from ADC measurement to millivolt may be done like this. You need to know the reference voltage of the ADC in the microcontroller.
If VREF is 3300 millivolt and resolution of ADC is 10 bits, scaling from ADC measurement to millivolt may be done like this: unsigned int millivolt, ADCresult; signed int temprature01; millivolt = ADCresult. 3300ul 10; temprature01 = millivolt - 500; /. This is temprature in units of 0.1 °C./ Calibration adjustments may be done by modifying the integer constants.
