WITH 4 DIGIT 7 SEGMENT TIME DS18B20 THERMOMETERS PIC16F628

Pic16f628 microcontroller-DS18B20 sensor clock thermometer based on the project has been very useful and detailed narration.

Pic16f628-DS18B20

On the streets, the streets often started to see their side – instantly claiming your dependability or your willingness to serve the public, Turkish people maybe advertisers pay attention çekmekdeki with the application of the new method of gauge, thermometer and clock.

In this study, 4 x 7 segment display, 4-digit, with a precision thermometer and 0.0625 C 00-23 time range, highly accurate digital clock. Hardware micro-controller Pic16F628A. The reason for this is, maybe it’s time to start my classic cümlelerimle, but have internal oscillator, and in this way reduce the need for hardware, I add a few low cost and feature, Timer 1 timer with external oscillator to run, and the callee can (sleep mode). Thanks to this feature, you need an external clock not only connected to 32,768 KHz (DS1302) Crystal saydırılarak hours were calculated

slightly larger than the 7 segments in hardware. 44 mm with a common anode 7segment displays, 74HC595 Shift registerlarıyla. The reason for this is that the hardware installation of the recorder’s preferred speed (1 of 1ns) and latch, and put çıkışlarıdır. In this way, the recorders installed in order, not necessary for the garbage characters and character erkanda 8 bit values after having been transferred to the outputs of the latch outputs recorders.

T1CO sucked inside the register, is shown above. In this study, T1CO 0b00001110 for the register value is stored in the startup configuration. So clock source (Bit.1) external oscillator, clock synchronization (Bit.2) has been passive and active oscillator (Bit.3).

Sistem başlangıçta 00:00 saat değeriyle başlamaktadır. Saat değeri 5 saniye görüntülenmekte, termometre değeri 5 saniye görüntülenmekte ve Antrak yazısı 4 saniye görüntülenmektedir.

Saatin ayarlanması için devreye 2 adet düğme eklenmiştir. Bu düğmelerde Saat Seç düğmesi bu işlemler tamamlandıktan sonra kabul edilmektedir. Yani saati ayarlayabilmek için ANTRAK yazısı yazmaya başladığında düğmeye basın ve bekleyin.
