Hi all,
I am a java newbie and I'm using NetBeans IDE 7.2.1. The complier reported that the file cannot find.
I have attached the file (match.wav) in my project folder.
This is my code.
package GemCrush;
import java.awt.Component;
import java.io.*;
import java.net.MalformedURLException...
?Initialize the rtc only once on power up I do not understand this. Do I comment the initialization of rtc after the rtc has been initialized once ?
Also, please refer to the following code,,,
void System_init(void)
{
lcd_init();
s_connectionreset();
DS1307_settime(0x10,0x40,0x30)...
Is you mean that it is no longer setting the information after I have set the information for one time? (The information has been stored in rtc when I set it one time??)

My rtc(DS1307) cannot remain the information(either date or time). I have connected the 3V Li-battery to pin3(vbat) and 5v to pin8(Vcc) together.
When I disconnect the 5v supply and then re-connect it, the rtc only starts to which I set to. Why happens this issue??
Hi all,
I have encountered a problem that I cannot send the correct data to the hyperterminal. I'm using KeilC51 complier and C++. Also, I set
the SMOD to 1 and using 11.0592 crystal(baud rate set to 4800). Sometimes send correct data, sometimes wrong.(like below figure)
I do not know what...
um,,you're right,,but I never success to connect the GPS module with the satellite within 1min
Anyway, I know that my module is work under my continuous testing.
As I read the AT89s52 datasheet again, I find the minimum input high voltage is 0.2Vcc+0.9 not 0.75Vcc which is maximum output high voltage.
In addition, the low logic from the Tx also pull high when I add the pull-up resistor. For ATxx, the maximum input low voltage is 0.2Vcc-0.1.
If the...
It still lighting that means the GPS cannot locate my position but the voltage in Tx pin have a change between 1.x~2.8v while the Rx maintain to 3.8v.
Ah...what's happen??
I have tested before around 5 months with max232 receiving in PC and stored the data in txt. Besides, I remember that it...
Oh, I have added the pull-up resistor(20k) on both sides(Tx and Rx) and tested it today but it's not work.
It's LED is lighting (searching location)
EM411 - twinkle means it located.
Have any ideas?
