 04 Oct 2008 20:57 Digital Clock (RTC) with Temp Help!!! |
|
|
|
Hey,
Please help me on this...
I need to make a Digital RTC with Thermometer. I wanna use a RTC with the DS18B20 Thermometer. I want to use the 12Bit accuracy. For RTC, if the function is with date, that's great. Need switch for +/- in time/date setting. Time can be 12h. All the data will be displayed in an lcd with 2 or 4 line display. back end can be an mega8 or pic16f86 or 87. best is mega8. please let me know...
also in case of firmwire, C is best... if any one has any idea, let me know please...
Mishu~

| Sounds doable, C is a good choice. What else do you need?

Hi, I send to you my code for digital time and temp, shown on 2x16 lcd.
I use MIKROBASIC from www.mikroe.com, DS1307 is connected to pic16f877 at 20MHz with SOFT_I2C (SDA = RB1, SCL = RB2), DS18B20 is connected on RA5. LCD is config to PORTD.
On first screen you will see in first row date and on second row day on week, after 5 sec you will see on first row time and on second row temp,
day of week is on Macedonian language, you may corect them (PONEDELNIK = Monday...),
work very fine, I do not use external key for adjust date and time, becouse RTC use external battery I put that info in RTC on my code directly,
If you have a question please mail me,
regards

The code is in MIKROBASIC from MIKROE.COM,
that is pic basic language,
If you prefer C, you may use MIKROC from MIKROE.COM,
