So much thanks to you Martin you're comments are really useful really appreciate it.
I hope that you want to continue helping me with problems I maybe have in the future.

Thanks again.

Hi, Martin I have made some changes to your flow code so I can Use it with my own program. And it works :) Thanks again. http://i56.tinypic.com/2v1ww9s.jpg But I have A little question for you, How can I use an interupt to update the temperature every minute. Now I have made a simple counter that co...

He Martin, I don't now how you have done this, but it works man wonderful. But I really like to know How the program works, If its not to much trouble, can you explain my step-by-step whats going on. Also I'm beginning to understand how the lookup table works but when I want to look where you get th...

Thanks For understanding,

Maybe I will understand you're method of making the LUT a bit better when its completed.
Looking forward to see the result.

Thanks Again for helping me out here, really appreciate it.

I really don't now what to do next. What are LUT value 10Bit H and L. I dont now what you are maining, because you said you only need two 8 bit LUTS because of the values you are retrieving! I really don't now what to finish because I have now Idea what to do. Why do I have to make 2 lookup tables. ...

I think this will do it.
I'm not sure maybe you can look it over for some errors.

Thanks Medelec

Hi, Medelec

Soo much thanks for your reply,
I'm working on a 10bit lookup table right now and I'm hoping to finish this tomorrow.
I really appreciate your support.

Hope we can make this work

Spanish_dude, I don't understand you're calculation When I read in 25*C because my lookup table says so (25 corresponds to a particulaire value) When I multiply this by 10 >> 25*10 = 250 what I need to do next is divide this by 2 >>>> 250/2 = 125 I don't think thats correct. Ore do I use the formula...

Hi spanish_dude,

Thanks for your reply.

About that,

Using floating point is not an option, because it uses to much memory.
but the seconde option sounds better but I don't fully understaint.
Maybe you explain in more detail.

Thanks,

Hi guys, I have A question related to my previous post http://www.matrixmultimedia.com/mmforums/viewtopic.php?f=7&t=8176 My temperature probe KTY-26 PTC. Is working correctly for sometime now. but only shows whole degrees like 25,26,27 but what I want is this 25.1, 25.2, 25.3 ect. But I'm not sure h...

Hi, Guys I have some trouble with my DS1307. I can write the time succesfully but when i'm trying to set the date (dd/mm/yy) I get strange values. I have copy't the calculation from the example file (RTC_4b.fcf) to convert decimal numbers into binary coded decimal numbers. I use DEC to BCD conversio...

To answer your questions first: 1. Yes I have tried to remove the jumper but no succes. 2. I'm controlling the contrast via an Pot. meter. What I have done, I thought about it because you said: The only other thing I can think of is if the wires plus the breadboard plus the more wires are causing th...

Thanks for your reply, and to answer your question; Yes I have my R/W pin grounded. I have also tried the 4 data lines connected on Pin 7-10 but that doesn't work either. So I reconnected the data lines to Pin 11-14 of my LCD but still doesn't work. and the strange thing is that the LCD on mthe EB00...

Hi, I'm really busy with my project and made some good progress. Monday I have bought A new LCD screen for my project from Conrad.nl. The LCD is an AV2040 with an KS0066 LCD controller ship on it. Thats the main reason I have bought it because the EB005 LCD board uses also an KS0066 controller. I ha...

Seems to be a clock error ? I have search the whole internet to find something/someone with a relation to my problem but i can find anything. Thats the only thing going wrong. I can set the time with an menu that I have made. and it loads correctly but the random values are showing up only when I h...

thats a pitty

What Can I do to so you can examine the file.

Hi all, I have a problem with my DS1307 chip. I use this example file (init_time_v3.fcf) to study the I2C protocol. My problem is as follow: First thing that I have done was remove the backup battery and disconnect the chip from the 5V supply. Then replaced the chip and connect it to +5V and reinser...

Hello, I have made a little program to write a certain time value into the DS1307 In my program I try to program the time 11:30:00 into the DS1307. But there are some things going on that I dont understand: first off all: This program is based on that from a example file called (init_time_v3.fcf) fi...

O,

one more thing do I need to hookup the SQW/OUT to my microcontroller.

Oke,

Thanks you very much for your explanation
really appreciate it.

regards Jordy

Oke, I think I begin to understand how it all works. I have grabbed my calculator end set the thing to HEX calculation mode. So b11010000 is 0xD0 and for b11010001 is 0xD1 so to start the DS1307 to listen to the I2C bus I need to: 1. output an start command 2. Transmit the external device address wi...

Hi, Spanish_dude Thanks for youre reply. I have checked the data sheet and it says to me that the device address of the DS1307 is 1101000. So I have made a little program what I think is right. http://img145.imageshack.us/i/naamloosxe.jpg/ But I don't understand how I clear the LSB. I've used an onl...

Hi, Benj The routine that I need to do, to read and write is now clear to my but what I dont understand are the following things: Transmit the External Device address with the LSB cleared. Can you explaine this to me in detail. because I dont now where I can find the External Device address and how ...

Hi everybody, I have made some real good progress since my last topic I posted here. I have made a menu where I can set the opperation into different modes and set the temperature levels for HIGH,LOW and NORMAL. Its all working nice, in the simulation. But now I whant to add an DS1307 into my projec...
