I have dumped the code in hardware and I2C is working. I am using PIC 16F887 and CCS-C compiler(version 4.093) plugin in MPLAB IDE. Try it again on hardware, you will success. while(i2c_write(0xC0)) // Device address 0x81-0xFF - Transmission completed and acknowledged respond with i2c_write()Įlse if(state > 0 & state 0x80 & state 0x80 - Address match received with R/W bit set respond with i2c_write() 1-0x7F - Master has written data i2c_read() will immediately return the data State = i2c_isr_state() //0 - Address match received with R/W bit clear

#use i2c(SLAVE, SDA=PIN_C4, SCL=PIN_C3, address=0xC0) There is little bit error in slave code, you can replace slave code with EX_slave.c example I'm posting master and slave code of I2c, it really work on real-time hardware. check if the value is not rolling over when you Try changing the place holder and see the result in hex. Look at something between 2.2KR, and 4.7KR, depending on the length of the bus.

'-1' reflects receiving the byte 0xFF, and the commonest reason for receiving this is that the bus is not properly pulled up. The 0x80 state, is 'unique', in that here a byte must both be read, and a new one written.Ĥ) You have got pull-up resistors on the two bus wires?. You are not doing this, and this could hang the I2C peripheral. On this, you _must_ read the incoming address byte before loading the reply. Study carefully what _must_ happen on state 0x80. Proteus will not complain about this, but it is likely to cause problems with some crystals.ģ) Problem with the slave code. For 4MHz, you should be using 'XT', not 'HS'. It can sometimes emulate some chips, but unfortunately does not reflect problems with real hardware, and will often just not work, for no reason, or work with setups that will fail miserably in real life.Ģ) Change your oscillator. If(state = 0x80) // Master is requesting data from slave #fuses HS, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP

The simulation results with 16f877 using Proteus is as follows(temperature measurement):

My objective is to communicate between two PIC16f887 controllers, where the slave controller collects sensor data and sends it to master controller which displays it on LCD and PC using RS232 connection. What should I change to make it work in 16f887 ? The code is as follows, I've made few changes in it. The code works for pic16f877 but it is not working for pic16f887. I used i2c code posted by PCM programmer to simulate i2c operation in proteus. I am using PIC 16F887 and CCS-C compiler (version 4.093) plugin in MPLAB IDE.
