Hi Jayanth
Lets say i just want to put the temperature at 25.3, so i will multiply by 10 to get 253.
unsigned float t=0;
val = ADRESH & 0xff;
t = ((val/255.0) * 500);
t = t *10; // 253
t = ?? // So how do i subtract 250 here since it wont be 250 everytime ...
Hi paulfjujo
I have got my LCD working now. I forgot the most impt TRISD out statement.
Thanks for the guidance.
Now im trying to make it look proper by trying to show the temperature as 25.x instead of just a whole number 25.
How am i able to do that ?
Hi paulfjujo
Yes, i am able to see "Hello World" when it is stored as a const rom char MESS[12] = "Hello World"
I am rather new to programming so my explanations may not be as clear and concise.
I seek your understanding but pls do guide me along. Thanks.
I will try out your short test when...
Hi paulfjujo
Pardon me for my ignorance on the ADC.
i have the following code for writing to the LCD as below:
/* Write text data in term of 4-bit at a time to LCD */
void W_data_4bit (char x)
{
LCD_RW = 0; // Logic ‘0’
LCD_RS = 1; // Logic ‘1’
LCD_TEMP = x; // Store text data...
Hi paulfjujo
i am using the 4-bit setup for the LCD so i cant use the full 10bits of ADC.
My setup is such that after i have the input from sensor, i will have a LCD function to process 4 bits by 4 bits and display it.
From my Watch window, i can see the correct display but it just cannot...
Thanks InNeedOfHelp.
I suppose you are using High Tech C compiler ?
I have still some difficulties. From my Watch viewer, i am able to get the temperature and its ascii code using itoa().
Now my problem is how do i write correctly the coding to display out these ascii code to the LCD.
I seems...
Are you able to help me with the coding ?
I have no idea where have the coding gone wrong as im not well versed in C++ and unfortunately the deadline for me is nearing and i have got to design a web page for this as well..
So your help is very much appreciated !!
Yes i did declare actually..
I put it in this >>>
ADCON0 = 0b00000001; // Select AN0 (channel 0) for Temp sensor, turn on ADC
is there anything that i have missed out ?
Thanks.
Attached is my schematic
Its an outdated one with a few pins reassigned as follows:
LCD module
RD0 >> DB4
RD1 >> DB5
RD2 >> DB6
RD3 >> DB7
Thanks, appreciated all help as im rushing before the deadline which is near and i have got to learn make a Web page out too..
Hi all,
Im new to C++ prog and i have a project which requires me using a 18f4520 with MPLAB IDE 8.80 and C18 compiler.
I have a LM35 which i will need to output the temperature value onto a 2x16 LCD.
Im using 18f4520 and making use of its ADC to do the conversion.
The problem now is that the...
