Digital hours to make this not too difficult. This series is not my original project, I trace the series of files and program from the internet, there is no chance the program listing. After I download the file to its hex-hour direct way. This clock only displays hours and minutes, to seconds However you can install the led associated with a series of I Hz oscillator formed from IC 555 (which I do, because I do not know the program listing), 2 led in parallel and installed as a bookmark seconds. Led to two installed in the middle of the hours and minutes. Although with the way that seconds and minutes if observed (calculated) decline slightly but I'm not the problem, Moreover people will not know about it. Digital hours following scheme:

To me its PCB design itself, of course are still using my favorite software, PCB designer. Next the PCB layout (look up) :

Rangkaian Thermometer Berbasis Mikrokontroler AT89S52

This is a circuit of a microcontroller AT89S52 Thermometer and 12-bit ADC LTC1298, programs written in the language c program with digital filtering and interface the LED display. The reading provides 0.1C sensitivity.

The hardware block and circuit diagram is shown in Fig below. The sensor is epoxy molded thermistor. The circuit for signal conditioning is a simple voltage divider. The ADC is 12-bit SPI interface LTC1298 analog-to-digital converter. The microcontroller is Atmel 89S52. The display has four digits 0.5 inches 7-segment LED. The segment driver provides 32-bit CMOS output.

Thermometer Block Diagram

The ADC is 12-bit (LTC1298 or MC3202) are two channels, CH0 and CH1. The input signal from thermistor for ADC channel 0 is simple voltage divider. Channel1 is available for other sensor. The sample shown in schematic is HIH-3160 Honeywell Relative Humidity Sensor. The ADC chip is interfaced with MCU, 89S52 with P1.1, P1.2 and P1.3. The display has 4-digit LED. The 4094 CMOS shift register drives the LED directly.

Software

The main function is time triggered by 10ms timer0 running. The ADC is updated on LED every 10 ticks.

while(1)
{
while(!cputick)
continue;
cputick=0;
print_ADC();
}
The function that reads 12-bit data from ADC is read_ADC(char n). The function has two loops. First loop is to send 4-bit command. And the second loop is 12-bit to shift the data from ADC.
sbit Data = P1^1;
sbit CLK = P1^2;
sbit CS = P1^3;


int read_ADC(char n)
{ int k;
char i,channel;
k=0;
CS=0;
if(n==0) channel=0x0d;
else channel=0x0f;

for(i=0;i<4 data-blogger-escaped-clk="0;" data-blogger-escaped-cs=" 1;" data-blogger-escaped-data=" 1;" data-blogger-escaped-i="0;i<12;i++)">

To provide smooth reading, I added the 5-point moving average to the raw data. The function low_pass_filte1( ) is used to filter the high frequency noise. The reading is calibrated to degree Celsius with Platinum 100 standard thermometer. We found the equation y=0.0323x-15.122.

int low_pass_filter1(void)
{
x5=x4;
x4=x3;
x3=x2;
x2=x1;
x1=read_ADC(0);
return(x1+x2+x3+x4+x5)/5;
}

float read_temp1_filter(void)
{
return(0.0323*low_pass_filter1()-15.122);
}
