[PIC] i2c converted to rs232 using pic microcontroller

[brilliant minds]

hi
i want to convert i2c protocol come from master pic micro controller to rs232 to help me to read it via hyper terminal.
rely i am not the protocol i want microc code and protues design
any one help me

your question looks confusing to me.If i am getting right you want to see the I2C code logic at hyper terminal ,then why you want to do that for see I2C code logic use logic analyzer would be easy.correct me if I miss understand your question.

interface large number of pic microcontroller

hi
i am trying to connect all this microcontroller to gather using i2c or RS485 I want the above 2 microcontroller send the data(any button for example send character or text) to the medium MCU (it has LCD)
and send the same data to the plew MCU and the last one send the data to pc via rs232
i want code to do that
this is picture link

Re: interface large number of pic microcontroller

What is your application exactly?why you want to use I2C? you can just simply use serial communication protocol.


Why you are using the Four controllers? You can just do it with the two controllers, if your controllers wont gone a place at far distances.

As per your image your above two controllers having inputs like buttons.
you can use the one controller with as many buttons you want to use.

Connect this controller to the other slave controller who has display lcd and who just transmit the received data to the PC.
