Thank you for clearing that up, the program now works as it was intended. I now am trying to use an RF transmitter over the serial connection between the PIC's and the program is interrupting on the g ...

OK, so I programmed the interrupt as you sugested and moved the variable declarations. I now have the following programs written trying to talk serially. I am only trying for one way at the moment, an ...

Thank you guys for the help, I got the serial to work using the carriage return and declaring the variables in the right spot (dumb mistake, thank you) and I will try using the interrupt on it shortly ...

I have a bit of really simple code I wrote up here trying to just make 2 PIC's talk back and forth to each other. I never really got to making any indicators (LED's) on the master 1st PIC because I ca ...

I tried the separate write sequence idea, but the program just seems to freeze up every time after the write process. Does anyone know of an existing I2C Slave program capable of writing and reading t ...

Sorry, I missed your last post. It appears that this has become even more complicated... I'll re-examine this to see if it is worth the re-writing of the EX_SLAVE.c program. If you have any easy modif ...

OK, here is the story. I skimmed this down to next to nothing, and it still doesnt work when trying to send multiple bits. When I comment out the sections making the program send more than one byte, i ...

Is the method I'm using to write the data correct?

OK, so here is the story. I tried to take the numbers out and put only a zero in the last i2c_read, but now the program just freezes and does not output anything. I did research this a bit, and tried ...

OK, so I attempted to apply that to what I am doing with the I2C communications between the PICs. I am just trying to see if it works by sending a 1 and seeing what it sends back. I recieve a -.000000 ...

how do you go about splitting it and re-assembling it?

I understand that a floating point variable uses a 4 byte size, I just don't know how to send 4 bytes over the I2C as one number. I am assuming the error in the code is in the writing and reading of t ...

I actually managed to figure out the I2C communications between 2 pics. I then expanded that to 3 PICs and got one to send characters. I am trying to transmit a float variable over the I2C, but have n ...

I have tried both the programs I have posted here and the programs you suggested, and I cannot seem to get the PIC's to communicate. I tried using different pins just in case it was a pin problem, but ...

I am currently trying to get two Pic 18F452's to send data back and forth between each other through an I2C connection. I have wired then together, pulling the SDA and SCL wires up to +5V through 1K r ...
