Hi there, I need more than 100 Kb memory for my application.I'm using ccs c compiler, 16F877, 24LC256 and proteus for desing.Can i use more than one i2c memory with same pins? I want to use 4 24LC256 on the same line (same pins of 877) Is it possible? If so, How can i use it? Any proteus dsn files for this? Or some brief will be fine for me :)

HI, Anyone can help me looking for routines driving a LCD with a embebed i2c controller PCF2119 ? ccs or asm is fine. I'll really appre3ciate your help. Rafa
SMBUS is an extension of i2c (or TWI, as it is also called, to avoid patent disputes with Philips). It has some special limitations and special reserved addresses SMBus added special broadcast messages within the i2c protocol. But everything is still addressed the same way, so unless a device is actually listening for the broadcast me

Hi new here, was wondering if anyone could help me out: I am using an example file by ccs for the driver. This is it: #ifndef EEPROM_SDA #define EEPROM_SDA PIN_C4 #define EEPROM_SCL PIN_C3 #endif #use i2c(master, sda=EEPROM_SDA, scl=EEPROM_SCL) #define EEPROM_ADDRESS long int #define EEPROM_SIZE 2048 //This is line
Dear all, I just changed from PIC16f690 to PIC16F876A. The PIC is used for motor driver application and it sends signals to the H-bridge VNH2SP30. The code written for PIC16f690 worked well with no errors. But now, I am getting some errors, mainly unknown keyword, unknown identifier when I try to compile the same code but this time for PIC16
hi, everyone... my project is doing the communication between 2 MCU with i2c connection. furthermore, in order to test the communcation between this two MCU, i using the LED and push button to test it. while i push the push button, the other MCU will be lite up the LED. i m using ccs C compiler to write the code. so, first all of i initialize the

I'm reading the 16 bit ADC value and displaying in LCD using MCP3421. When i use inbuilt i2c functions in ccs, everything works good. But I'm trying to use the registers and displaying the value. Below program shows how i configured. But in the display, it shows different value what i expect. Please help #include "18F2520.h" #include "f252
I have written a program in ccs C. It is for i2c communication between One Master PIC16F887 and two Slave PICs PIC16F887. When I use any one of the slaves the master reads the data from slave and displays it on masters uart but if I use both the slaves then it reads data from slaves and prints it on uart the first time and after that it reads 0 fro
Did you notice the 25640 driver code shipped with ccs C?
Hi for all, can somebody share some working C code (mikroC or ccs C or any...) for i2c communication between one PIC16F887 like master PIC and one PIC16F887 like slave pic? thanks in advance and best regards
you should check the EEPROM's datasheet for time delay but i2c message carries its own acknowledge bit, so you can check that bit and if OK, go on to send. For more information read your compiler's manuel. i'm using this example from ccs c compiler's manuel: int1 ext_eeprom_ready() { int1 ack; i2c_start(); // If the write co

Somebody can send me an example using multiplas 24LC256 with 16F877 ? if possivel using the compiler of the ccs. Very Thanks Orcino
I am developing a system that needs to be expandable. The system uses PIC micro (16F876), and simply counts input pulses and stores values to external i2c memory. The system can contain several of these counter devices. One main PIC then collects info from the Counter PICs and/or i2c memory and passes this data to a PC via a RS232 Link. The mai
