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 :)
example code use i2c interface DS1307 whith pic c ccs.
i need example code ccs interface PCF8583 it make send interrupt every 10 sec to microcontroller. plese help me.
Hi. Here is part of revision history on ccs compiler versions: "3.223 A problem with i2c_START() on some parts is fixed" Best Regards.
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
This code is for ccs... Rafael
If you used ccs PIC C. you can find from
Hello Everyone . Well After Building a Audio Transmitter Now i want to transmit Video Signals as well I have found This great IC . it is a VHF Audio/Video Modulator with RF Output level of 82dbuV . and i think if i connect a input of a camera and then connect an antenna at this IC's RF Out Pin and Tune into my TV i would have a Video Transmitter.

Hi, I'm using ccs compiler.
Hi, Does any one is using ccs-IDE for PIC programming..... I have written a code for i2c, but it is not giving the required result... i was thining to see the code generated from ccs-IDE wizard.... if any one can generate the code for PIC16F818, then it would be helpfull for me for refrence...
Hello every body, I´m starting in the programing of PICs using the ccs,.. So I need Help to make a Master Slave using the RS232 Interface. This is the Idea: Use the RS232 as a interface to work as the Bus i2c do it. Thank you ClK
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 noticed the same behaviour at PIC16F87x with ccs compiler, at real-world circuit, not simulator. Coincidentally, I had to change the mode from Hardware to Firmware, but I had not time to investigate the reason at that moment. +++
Hi, I am using PIC 16F887 and ccs-C compiler(version 4.093) plugin in MPLAB IDE I have dumped the code in hardware and i2c is working. now , i do not know at what speed the i2c communication is taking place ? can u help?

Hello team, I'm trying to communicate two devices using i2c protocol in assembly: PIC16f877A and AD5301. I have simulated my assembly code in proteus 7.9 sp1 and it works fine but physically does not. I thought it was my pcb but it isn't: I proved another program in ccs C language in the same pcb and componentes and it works very well, th
hi I have got minIMU 9v2 sensor whicg=h is combination of accelerometer, magnetometer, gyroscope, i dont no how to interface with pic controller. any one help me to write coding for pic using ccs compiler to interface this sensor with pic using i2c.. regards
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 see some differences to ccs example code respectively compiler manual suggestion given with i2c_isr_state(): - address isn't read for state == 0x80 (read address received) - there are extra i2c_read() calls for state > 0x80 I must confess however that I didn't yet implement i2c slave functionality with (...)
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
Somebody can send me an example using multiplas 24LC256 with 16F877 ? if possivel using the compiler of the ccs. Very Thanks Orcino
Library for what compiler ? many library in Asambly or on the web site of microchip. Or if you what in C you can use many compiler, but I like ccs because it's come with a lots of library. i2c, SPI, serial, ADC, timer, Real time clock, etc... I thing is the most complete.
You can find i2c application in C at or at ccs compiler. You can use also 9bit serial communications.
I would recommend the ICD1 instead. The circuit is just as simple, although component cost is higher with an additional MAX232 and a 16F876. But in time to come, you will appreciate the ICSP capabilities during PIC development. When flashed with ccs's firmware, you can even run/stop programs using software, not having to touch your setup at all dur
see information here : and information about BoostCTM the next generation C compiler :
Better use ccs C compiler, it has ready function to execute an i2c command.
Here are samples in the ccs c-compiler. Hope it helps.
Hi. You can go to ccs website, download their "Embedded C Language Exercise Book" It is an exercise book to work through i2c, RS233 , ADC interrupt etc with PIC MCU. Circuit is provided in the book You can download a lite version of their compiler for testing also
Which are you development tools? C, ASM ? In ccs C compiler you have many built in functions to access EEdata and many divers to inteface external memories even though the PIC used doesn't have any i2c nor SPI.
Hello, If you are using ccs C compiler you will get sample code for DS1307. Bye
HI all Is there a software who can simulate the TMS320C6713 CPU and peripheral desvices (McBSP, i2c,...) ? I've tried ccs 3.1, but it has only peripheral registers. Thank in advance muoinho
I have just started working with DSPs and my main query concerns the hardware topic. OK, with MATLAB and ccs it is very easy to download and run a program in DSP but how can you connect a DSP with hardware, resulting in a complete system? For example how does a DSP interracts with the other circuits in a cell phone? With a microcont
How can i read the time and date from this chip. Day month and year?? I have ccs-C Did anyone have sample code to do this. I have this code so far #include <18F4620.h> #use delay(clock=20000000) #fuses HS,NOWDT,NOBROWNOUT,NOPUT,NOLVP,DEBUG,NOSTVREN,NOPROTECT #include #include void main() { lcd
I think its not just C but ccs. And its used to set a Soft- or Hardware i2c master #use i2c(master, sda=PIN_B0, scl=PIN_B1) will set and i2c master in RB0 & RB1 and will be used with the subs i2c_start(); ack=i2c_write(DATA); val=i2c_read(ACK); (...)
Use ccs C then implement i2c.
hello can anyone give some link or example of implemeting a software SPI in a PIC16f84 using C language thank you Use ccs C, problem gone in using SPI.
Sir, I am new to Micro chip microcontroller environment.I am about to select a compiler(for 12/14/16/17/18 series PIC mcu) for our project.We have to select between Hitech Pic C and ccs Pic C compiler.But price difference is huge. Can anybody help me to choose one of them and why? And what should be the compiler evaluation factors based on
please tell whether this RTC used SPI or I?C Did you lost the datasheet? i2c is written on the title page. You should try to locate it, cause it has other valuable information for your project, too. DS1307 can obviously be accessed through MSSP, but unfortunatley I can't help with HI-TECH related code. I prefer the possibly less p
Dear all, I am intending to begin program with PIC microcontrollers (8 to 12 bits, like in e.g. PIC16F84) to be used to control PLL applications (i2c, SPI interfaces) among other small application involving collect signals. As I will begin from the scratch, I would appreciate to know which is the recommended kit for very beginners and what wo
