Incorrect connection of the wires on ATmega164

[robi10101298]

Hello guys,I'm trying to build a graphic display thermometer in Proteus, with an LM35 sensor using the ATmega 164 microcontroller.

My problem is that I don't know how to connect the temperature sensor to the microcontroller. When I'm trying to program this using the CodeVisionAVR I'm receving only errors, what can I do?

• What am I doing wrong?
• Are the wires connected OK? If not, why?

What am I doing wrong?

You don´t tell us which errors you get.

******
I don´t like simulations like this. Because they are far from reality.
* no AVR power supplies
* no AVR Ref voltage
* no AVR clock frequency
* no power supply capacitors
* no LPF/bypass signal capacitors
* no LCD power supply
* no LCD contrast voltage
* no code
* no timing information

Everything may cause a fail on real circuit. Some may even cause a fail on simulation.

* and maybe it´s a programmer/programming problem. Here we don´t have any infromation.

I´d say with the given informations it´s about impossible to help. ... just guess

Right now I'm not interested in doing ,,the real thing", it's just for learning purposes.. I have made a code but I can't display the temperature on the display, I can only power it...Can you please help me?

Hi,

did you read my post?
* about error description --> If you don´t post an error description, helping will be difficult
* about power supply --> If you don´t connect a power supply, the microcontroller won´t work
* it´s not sufficient that there is a code line "// Voltage Reference: 1.1V, cap. on AREF#" ... while there is no cap on AREF in real circuit.
* ...

Maybe the posted schematic does not match the real circuit --> then post a valid schematic (how else can we know how your circuit looks like)

I don't have any error displayed since the program that I have here compiles successfully, but as I've said I can only power the display and that's it..The power supply it's connected from the pin nr 4(Reset)

This is what I have now: My problem is that I can't translate mikroC code to CodeVisionAVR language How can I translate this to CodeVision Code:

char arr[11]="0123456789";

int res = 0;

res=ADC_Read(0);

          LCD_Chr(2,1,arr[res/100%10]);

          LCD_Chr(2,2,arr[res/10%10]);       

          LCD_Chr(2,3,arr[res%10]);

This is the final code:

Sorry, I've edited the code meanwhile but it's not working as expected..

 

[KlausST]

but it's not working as expected

Another useless information, because nobody knows what you expect and what you see instead.

You randomly jump from a wiring issue to a programming issue to a compiling issue to a language issue..... I can´t follow this.

I´m out. You need someone else who has more patience.
Good luck.

Another useless information, because nobody knows what you expect and what you see instead.

You randomly jump from a wiring issue to a programming issue to a compiling issue to a language issue..... I can´t follow this.

I´m out. You need someone else who has more patience.
Good luck.

Sorry Klaus, I'm a beginner in this area, I just want to pass my subject and I don't know what to do, I have a teacher that doesn't want to help us so I need to figure out myself how can I solve this problem... What I need to do is to build a graphic display thermometer in Proteus, with an LM35 sensor using the ATmega 164 microcontroller. My problem is that I've successfully turned on the LCD Display, but it's not taking the temperature from the sensor because I don't know how to do this using the CodeVisionAVR compiler...

Hi,

O.K. one last try:

You need to:
* focus on one item. One!
* provide complete information for this item.
* answer questions.
* give useful feedback on the given recommendations.
* give feedback when an item is soved.
* give feedback when you move to another item.

My recommendation: Start with the real circuit. Photos, complete schematic, additional informations, clear detailed question.

Unfortunately I don't have the access to some real components...I couldn't find on the internet a complete schematic for ATmega164 and LM35 sensor, so that's why it's a little bit complicated for me to do it...

To rewrite my question:

So, what I want to achieve in this is project is to build a circuit that can measure the temperature using an LM35 sensor from the ATmega164 board. I'll draw this circuit using the Proteus and I'll write the code using the CodeVisionAVR. What I've achieved until now it's that I can successfully display a text on the LCD. I've attached to you how my schematic it's looking:

And this is the code:

Assuming that the simulated dispaly is showing the text you show in the diagram
i.e
Temp is:
? 13 A3
then the program is doing alost exactly what you are telling it to do. I would have expected the second line to be
? 13 13, so there is somethiing to be fixed there as to why is the first 13 OK and not the second, when your code is printing
? 13 13 to the LCD.
The reason you are not getting anything else is that it doesn't look like you are not telling it to do anything after lcd_putsf("? 13 13 ");
The program is just sitting in a while loop.
The comment // Place your code here in the template is there for a good reason.
If there is no code, unless you have set up timer interrupts to do the work nothing will happen.
I'm not familliar with the ATMEGA and don't have the inclination to work through the set up code to see what interrupts you have set up.
I can't see any code outside the two statements in the main function that writes to the LCD. At first look it seems you need to write some code in the while (1) loop to read the ADC convert the binary value to degrees C then dispaly the result.
