I am a beginner on PIC Programming and using PStart Programmer for programming (asm). Can anyone help to provide on a Static LCD display (1 line 16 digit) sample program source code, for displaying Temperature eg 12.5°C with range from 0°C to 30°C when the control input voltage varies from 0V - 10Vdc or 0V - 5Vdc using a PIC16F84A Chip?

I did it before using Microcontroller, so I'll explain the idea and you can translat it into HDL.
Suppose you have number equal 32 (in binary form and you want to covert to decimal
1- Divide 32 by 10 --> it will produce 3 and the renaider is 2
2- the remaider 2 is the least significat digit in decimal number you can use a table like to generat t

If u r using a 'C' compiler, you can directly use the following algorithm:
1) Value = ((High order byte) * 256 ) + (Low Order byte)
2) Create a 16 bytes buffer array in the uC RAM area
3) Use the sprintf() function to format the result and send it to your RAM buffer.
4) Send the buffer contents to your LCD service routine. This buffer will be

Here is a solution assuming you have 32 bit integers.
The result you want is called BCD (Binary coded Decimal) meaning each decimal digit is represented by a binary number, in this case a binary integer.
int val = b2 * 65536 + b1 * 256 + b0;
const int NUM_BCD = 8; // ffffff = 16,777,215 : 8 bcd digits max
int aBCD = new int

Ideally this is how I would break down the problem,
First make a assembly routine that correctly displays a digit given the appropriate number - such as 5 produces a '5' on the LCD
Convert the integer number to a hexadecimal value using assembly - search the net, there are several examples.
By using integer division extract the digits in t

To move to the next instruction with the 16F series you can use $+1, but for the 18F which uses 2 byte addressing you must use $+2.
That bcd example uses a lot of $ instructions you must correct - I usually replace them with goto / labels then the code is compatible with either series.

There's a lot of confusion in your code. hex2dec doesn't work because you apply atoi() on numeric values, but it only works
for null terminated ASCII strings. Furthermore, I don't see the purpose of applying atoi(). The digit array contains already
the numeric values, that can be output to your display.

I've not checked your code deeply, but don't you forgot the instructions "out PORTC,Rxx", and "out PORTB,Rxx"? Without these instructions, you're not changing the values on the ports, so you are not generating the signals to turn on the leds.

the time and date are in BCD format - check that you are decoding them correctly

unsigned char BCDtoDec(unsigned char hex)
return (hex >> 4) *10 + (hex & 0x0f);
