Hi,
How many bytes are you trying to write and read and what mode are you using
AT24C04 has page read/write mode and random register read/write mode
if you are using page read/write mode, then at the end of each page, it will roll over to page start and you will experience some corrupted data...
Hi,
I am a beginner level developer and until now I have been working on PIC18 & PIC16 using MikroC compiler. But now I am working on a project with LPC2138, an ARM7 based MCU from NXP, using Keil uVision.
The project includes GSM module interfacing, EEPROM, SD card, different digital (with I2C...
Hi Stefano
I guess you are almost right ... I found this chip on another tracker from the same company :)
and alas ... no ... I was never able to find any document about xt3442.
P.S. very sorry for delayed response.
please post a simplified schematic diagram of your setup. you can simplify it showing only one led. It would be much easier for us to understand the problem that way.
Did you connect RW pin to GND?

Try this code
char *text = "Hello World"; //Constant holding text to be displayed
// Lcd pinout settings
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
sbit LCD_D7 at RB3_bit;
sbit LCD_D6 at RB2_bit;
sbit LCD_D5 at RB1_bit;
sbit LCD_D4 at RB0_bit;
// Pin...
Thanx guys
A little more info :
The circuit needs to be installed in car so voltage source is car battery.
The regulator is switch mode voltage regulator :: xaccto , I have no idea if it can produce any negative voltages ... plz guide.
As cars have very noisy electrical environment specially...
Hi guys,
I have a circuit I am trying to understand. In the power input section, it has two protection diodes D1 and D2 (see attached diagram).
Now what i understand is : D1 is for reverse polarity protection. I am not sure what D2 is doing in the circuit. Diodes in this config (D2) are used to...
hi guys,
I have this board and it has IC (xt 3442) on it. It is connected to I2C bus of ARM7 and considering the board design, I am pretty sure this is an EEPROM.
It's marking is : [first line = xt3442D] [second line = 98k60]
it's an 8 pin IC and connections are [pin 1 = VCC], [pin 8 = GND]...
