i am using pic 18f4620 with ccs complier. i am constantly writing a count value in ds1307 ram (i2c 400khz), then i am running a timer interrupt for erery 500ms it will call a isr in the isr function i am togging a led. my doubt is will there be any issue in ds1307 ram count writing if interrupt comes, i am using software i2c only.
Hello everyone . I tried to use dspic30f3012 with i2c on ccs program and all's right. Now I'm trying to use the dspic with i2c on Mplabx. I used the mplabx with xc16 and this is the code : #include<i2c.h> void main(void ) { unsigned int config2, config1; unsigned char *wrptr; unsigned char tx_data (...)

in my pic microcontoller 18f4620 i am connecting ds3231 rtc if i use the hard ware i2c it is working fine . if i change to soft i2c and and intrupt the main power 4 - 5 times one of the instance time in ds3231 changes how to solve this issue. can i add low pass rc filter on scl and sda lines? my pull up resistor is 2.2k i2c speed is (...)
i connected a ds3231 rtc to pic 18f4620 if i use soft i2c ( ccs complier) the rtc is working good if i switch off and on the main power for 3 are 4 times one time the day or time changes how to solve this problem. the soft i2c settings are : #include <18F4620.h> #device ADC=16 #FUSES NOWDT //No Watch Dog (...)
Here I am posting mikroC PRO PIC code for multiple i2c LCDs. With this you can have a device like DS1307 of i2c bus and also 8 i2c PCF8574T based LCDs. I didn't post this in my previous thread in DIY section because its title had ccs C Project but this is mikroC PRO PIC project. I have used these i2c (...)
This is Multiple i2c LCD code. It is written using ccs C Compiler version 5.044. This si tested in Proteus and also EasyPIC v7 development board with 2 x 20x4 LCDs. LCDs should be HD44780 or compatible. I have used i2c LCDs and i2c LCD modules from Banggood. I will soon post mikroC PRO PIC and AVR versions of the code (...)

Hello everybody,can you please help me to think on the implementation of a digital clock with PIC16F877A and PCF8583? I am new in i2c programming in ccs c ;please help.
In the past I have used ccs C Compiler that has built in functions for just about anything that we might want to do. These include: RS232 I/O, SPI two wire I/O, Discrete I/O, Parallel port, i2c I/O, Processor controls, Bit/Byte Manipulation, Standard C Math, Voltage Ref, A/D Conversion, Standard C char / String, Timers, Standard C memory, Capture
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
Did you notice the 25640 driver code shipped with ccs C?
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 (...)
i want to use tmp100 temperature sensor with 24F16KA102 in ccs picc by using software i2c. i am confused about acknowledgment in i2c. Second how can i convert data in to decimal. i need only decimal . here is sample code #use i2c(Master,scl=PIN_b4,sda=PIN_B6,SLOW) i2c_start(); (...)
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
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
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
Is anyone how know how to receive data from sht25 sensor to a dspic33 microcontroller using i2c protocol.(i used ccs compiler.) and then sent this data over rs232 ??????? Thanks in advance.

Hi I am trying to interface external memory 24c02 in proteus 7.7. But can't figure out what is the problem. Objective is to Write some data on memory, then retrieve it and display on LCD. Do i need to add this line in file #use i2c(Master,sda=PIN_C4,scl=PIN_C3) schematic h
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? Master code: #include <16f887.h> #device ADC=10 #use delay(clock=16000000) #fuses HS, NOWDT, NOPROT
Please use ccs C PIC and enjoy the programming world
The SRF02 documentation tells clearly about a 16 bit result. You simply have to assemble both bytes. With ccs you have the built-in make16() function for this purpose: result = make16(rangehigh, rangelow);
dear slurp ccs have a lot of helpfull examples ready-to-use concerning i2c memories ( 24Cxx ) once you had installed it to your PC. Make a search on Help and examples folder. +++
I have a project and I can't figure it out why it isn't working the i2c. I need to transfer some data from a PIC16F877A to another using i2c. Here is the code: Master.h #include <16F877A.h> #device adc=10 #FUSES NOWDT //No Watch Dog Timer #FUSES HS //High speed Osc (> 4mhz for PCM/PCH) (>10mhz
Hopefully you are talking about the following link ccs :: View topic - Driver For SHT75 Temperature & Humidity Sensor The output is based on i2c then why you are using portb pins #define sht_data_pin PIN_b1//(Data pin veya input) #define sht_clk_pin PIN_b0 use as defi

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
Use ccs C then implement i2c.
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, 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...
If you used ccs PIC C. you can find from
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

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.
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.
Better use ccs C compiler, it has ready function to execute an i2c command.
i need example code ccs interface PCF8583 it make send interrupt every 10 sec to microcontroller. plese help me.
example code use i2c interface DS1307 whith pic c ccs.
You can find i2c application in C at or at ccs compiler. You can use also 9bit serial communications.
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 :)
